2.2 Where the Hierarchy Appears: Burial Practice

Where within the settlements hierarchy is barely visible, burial practice paints a quite different picture. Elite kurgans differ sharply from ordinary graves on every parameter — size, construction, grave goods, ritual complexity. The richest include timber-framed chambers, bronze weapons, mass horse sacrifices — up to eight horses in a single burial — the imprints of spoked wheels, and sets of bits, with ornaments of gold and silver.

The principal source of palaeogenetic data is the cemetery of Kamennyi Ambar 5. And it is precisely this that makes the Sintashta picture unexpected. Beneath a single mound, and sometimes in a single grave, lie people from different male lineages — representatives of different genetic clusters in a shared sacred space. Close relatives among the buried are on the whole few, but within individual kurgans stable family cells are recorded: the most telling is three full brothers in one kurgan, sharing a common male and a common maternal line (see the Appendix to Chapter 2).

This is a double principle of cemetery organization. On the large, political scale different male lines are buried together — as participants in a single alliance. On the small, familial scale lineage cells are preserved within the common structure. Before us is a direct archaeological reflection of a multi-lineage alliance: of many parallel male lineages held within a single polity not by blood kinship but by common ritual and social institutions.

2.3 The First Pillar: The Horse

Sintashta is known above all as the point of birth of the war chariot. The light two-wheeled spoked vehicle, three times lighter than wagons with solid disc wheels and able to manoeuvre at speed, with bronze bits and bone cheekpieces, is the oldest known — though the question of priority remains open. The chariot complex occurs exclusively in elite contexts: it is not transport for all but a marker of status, of military function and of sacral competence. Mass horse sacrifices in the same kurgans add a ritual dimension — the horse becomes a mediator between the world of the living and the world of the dead.

Figure 5. The Sintashta chariot complex: an infrastructure of speed — light spoked wheels, bronze bit and bone cheekpieces (psalia) — attested only in elite burials (§2.2).

In recent years the palaeogenetics of the horse has become one of the liveliest subjects of debate on the Bronze Age. L. Orlando’s team (Librado et al. 2021; 2024) proposed a chronology in which ‘effective domestication’ — the appearance of the DOM2 clade — falls about 2200—2100 BCE, synchronous with the Sintashta chariot. This position was contested by the review of D. Anthony, M. Trautmann and F. Heyd (Anthony, Trautmann & Heyd 2026, Science Advances eady7336): domestication, on their argument, was a protracted and regionally variable process, beginning as early as the fifth — fourth millennia BCE, with several parallel clades and the systematic use of the horse already in the Yamnaya horizon (c. 3200—2600 BCE), long before Sintashta.

In this picture Sintashta is not the ‘cradle of horse culture’ but an integration node: a place where the DOM2 phenotype met the chariot complex and the metallurgical infrastructure. The debate over the precise chronology of each stage continues; for our chapter the structural fact suffices.

In the Sintashta horizon three components — horse, metal and inherited power — converge for the first time into a single configuration, one not found in the preceding horizons.

And one further distinction, fundamental to the whole chronology of the volume: ‘horse’ at Sintashta means chariot power, not mass cavalry. Mounted warfare will come only at the close of the second millennium, the cavalry army in the first millennium BCE. But even in its chariot form, control over the selection, breeding and training of horses meant differential access to speed — and speed on the steppe is a resource of a special kind: it sets military force, the range of communication, the capacity to coordinate space. Whoever controls the horse controls the steppe.

2.4 The Second Pillar: Metal

Sintashta metallurgy is not a local craft but an element of the infrastructure of power. At Ustye alone the finds of metal production run into the thousands — slag, ore, crucibles, tuyères, ingots — beside furnaces of the most varied construction and copper from nine sources scattered over hundreds of kilometres (precise parameters in the Appendix to Chapter 2). This alone implies stable exchange networks drawing raw material from different districts of the southern Urals, and perhaps Kazakhstan; control over these networks may have been one of the key resources of elite power.

The standardization of weapons — socketed axes, daggers and spearheads of stable types — betrays a professional tradition with a firm canon, working in three principal alloys: pure copper, arsenical bronze and the rarer tin bronze. This tradition was not isolated: as Hanks (2010) stresses, Sintashta metallurgy is embedded in the Circumpontic-steppe metallurgical province (after Chernykh). And the casting moulds, crucibles and slag in the elite burials themselves point to a sacralization of knowledge: power over the transformation of ore into weaponry and prestige combined technology, ritual and military function at once. The smith at Sintashta is no craftsman. He is almost a priest.

2.5 The Genetic Picture: Alliance from the First Day

When the first detailed Sintashta palaeogenomes appeared in the second half of the 2010s, the picture proved the direct opposite of the earlier model of a ‘homogeneous R1a society’.

If you imagine Sintashta as one great family with common ancestors — abandon the thought. In the Kamennyi Ambar sample some fifteen male lines stand side by side, falling into three large groups. The majority of the men carry the Fatyanovo heritage of R1a, with several parallel branches already within it. A minority carry the relict Yamnaya line R1b — and in three different clans with three different fates: one a widely distributed Yamnaya marker; the second a Samara — Volga clan that vanishes from the palaeogenomic record for good; the third a rarest line that will surface only some two thousand years later, in a single Türkic warrior of the central steppe. And, finally, two men carry the Okunev Q — the line of the autochthonous population of southern Siberia. Three groups, different trajectories — and all of them lie in the same kurgans, as one elite community (exact proportions in the Appendix to Chapter 2).

The first discovery was hidden in the dates. The central male line of Sintashta, R-Z93, proved to be older than Sintashta itself: the same line was already present in the Corded Ware cultures and in the Fatyanovo culture of the Upper Volga five to eight centuries earlier — the earliest reliably dated bearer lived near Yaroslavl around 2700 BCE. The Sintashta elite did not engender the R-Z93 line; it inherited it from the preceding East European horizon.

What this means. Sintashta did not create ‘special genes’. It inherited a ready-made line — and by the time the culture crystallized, that line had already diverged into eight parallel branches, each facing its own millennial fate. To this fan we return in §2.6.

The second discovery came from the east. The Okunev Q at Kamennyi Ambar consists of male lines of a population whose homeland, the Minusinsk Basin, lies two thousand kilometres away. And they are already here — and an identical Okunev subclade is attested in Khakassia two to five centuries before Sintashta, which makes the hypothesis of early contact strong. But the movement was one-directional: among dozens of maternal determinations there is not a single classic Okunev marker. Only the men came. This is the first, protocol form of that dual R+Q configuration which, half a millennium later, will unfold in the Orak-Ulus Synthesis (Chapter 3) and will go on working as the structural partner of the R-line in all the volume’s subsequent horizons.

And the third. If the male lines are gathered into a few large families, the maternal lines are the complete opposite: almost exclusively western Eurasian, but scattered across the most varied haplogroups, with origins from the Balkans to the Baltic. One signature is especially eloquent — the line U2e1h, carried by several Sintashta women, attested earlier in the Balkans and Central Europe by a century or a century and a half. Women bearing this line came from the west, probably from the Fatyanovo — Abashevo milieu; and after Sintashta the same U2e1h travels on — into the Andronovo horizon, to the early Scythians of Swat, to the Sarmatians of Uyuk. This is a matrimonial relay: western wives marry the sons of the Sintashta elite, their daughters marry the next wave of chiefs, and so on from generation to generation.

Behind this picture stands a familiar logic. ‘A narrow set of male lines alongside a broad spectrum of maternal ones’ is the classic signature of a patrilocal-exogamous society, in which the men remain in the lineage and inherit status while the women come from different populations along allied networks. Sintashta works in exactly this way — and works literally: the proportion of ‘foreign’, western Siberian autosomal admixture among the buried is appreciable, and people from biologically different populations lie beneath one mound, sometimes in one grave. Biologically, different populations. Socially, one elite group.

2.6 The Third Pillar: Inherited Power and the Eight Roads out of Sintashta

Now the most remarkable thing. By the time the culture crystallized, the central line R-Z93 had already branched into eight parallel branches, and each was to become the root of a separate phylogenetic trajectory for the historical horizons to come.

An important caveat at once: these are phylogenetic labels, not historical attributions. The conventional label of a branch does not mean the presence at Kamennyi Ambar of ‘proto-bearers’ of any later ethnic group — it means only that a subclade which centuries later will become diagnostically linked to particular descendant horizons is already differentiated in the Sintashta cemeteries. The people of Sintashta did not, and could not, know where their descendants would be carried thirty generations on. But genetics has preserved it.

The framework of the fan rests on the convergence of two kinds of data: palaeogenomic samples record eight terminal subclades descending from R-Z93 in the Sintashta cemeteries, while an independent Big-Y phylogenetic survey (FTDNA Discover) documents the full descendant structure of R-Z93. Some branches are confirmed directly, the rest reconstructed from a combined base — the archaeogenetics of descendant samples, the geography of present-day Y-projects, the historical-archaeological context. The full phylogenetic passport of all eight branches, with basal nodes and canonical dates, is set out in the Appendix to Chapter 2; here what matters is not the nomenclature but its meaning.

And the meaning is twofold. First, for our volume the central of the branches is the one running through the node R-S23592 (around 2200 BCE), the principal Central Eurasian node, which two centuries later will become the core of the Orak-Ulus Synthesis. Below it lies the node R-YP1456, splitting off around 2100 BCE — that is, exactly in the heyday of Sintashta; it is this line that will become the trunk of Volume I. (Its palaeogenomic appearance at Orak-Ulus around 1700 BCE, which we shall meet in Chapter 3, lags the node’s calculated age by some four centuries — a normal interval between the rise of a subclade and its archaeological attestation.) Parallel to the eight R-branches runs a ninth axis — the Okunev Q, represented at Kamennyi Ambar by two men: the proto-form, already familiar to us, of the dual R+Q configuration.

Second — and this is the main point for the model as a whole — the fan is not ‘invented’ later. It is already built into the Sintashta horizon: by the time the culture crystallized the root line is branched, the dispersal programmed in advance. This is the fundamental property of the Alliance component — multi-lineality from the first day, not a later superstructure.

The three pillars — horse, metal, dynasty — form here the technical and social infrastructure of power. Their ideological articulation — the synthesis of Steppe Verticality and Local Horizontality — we reconstruct in Chapter 4; their first mature synthesis with an autochthonous society, in Chapter 3. For now the moment of crystallization itself stands recorded.

2.7 Why Here, and Why So Fast

Complex non-state societies of the Bronze Age arose not only in the southern Urals — there was the Scandinavian Bronze Age, there was Mycenaean Greece, there was Shang China, with comparable levels of military organization and craft specialization. The Sintashta configuration differed in one thing: it joined control over mobility (the horse), over resources (metal), and over the reproduction of the elite (inherited power within a multi-lineage structure) into a single system able to work on the steppe — without cities, writing or bureaucracy.

Why the southern Urals? Because three conditions coincided there at once: pastures, accessible outcrops of copper ore, and a crossroads of steppe corridors. It was this resource node that allowed the three pillars to grow at the same time — stockbreeding gave the base for horse-rearing, ore for metallurgy, the crossroads position for exchange networks and marital ties.

And why so fast? Eighty years for a whole culture is not evolution but a phase transition: in the terms of complex systems, the moment when the coincidence of environment, structure of interaction and energetic base gives birth to a qualitatively new configuration within a few generations. When the conditions changed — the exhaustion of ores, demographic pressure, an external threat — the configuration did not disappear. It was transmitted east through the broad Andronovo horizon. And it scattered fanwise.

2.8 The Andronovo Fan: The Empirical Skeleton of the First Process

After the close of the Sintashta phase proper, around 1800 BCE, the macro-branches of the R-Z93 fan dispersed across an enormous range. This post-Sintashta horizon is documented by a palaeogenomic corpus of several dozen samples from some fifteen sites across Central, Eastern and Western Kazakhstan, Zhetysu, the Upper Irtysh and the Minusinsk Basin (the full corpus in the Appendix to Chapter 2). This is the empirical skeleton of the first process — the fanwise dispersal — and if its stops are set out in a line, a road to the east can be read.

At Maitan and Ak-Mustafa (Central Kazakhstan, the start of the second millennium) the line R-S23592 first shows through — the very one that two centuries later will become the core of Orak-Ulus. At Ak-Togay (Eastern Kazakhstan) it is already represented by two synchronous male burials. At Koken-3 on the Upper Irtysh it reaches its greatest density in the corpus — three bearers of R-S23592 in one multi-lineage cemetery, beside other R-lines and a parallel Q. The Zevakino cemetery in Eastern Kazakhstan reproduces the very principle of the multi-lineage alliance — a late analogue of Kamennyi Ambar, repeated in another region five to seven centuries on. And Ust-Bir IV (around 1607 BCE) closes the eastern arc of the fan already in the Minusinsk Basin, throwing a biological bridge to the material of Chapter 3.

Structurally the whole horizon says one thing: several parallel subclades diversify at the same time within a single geographical arc — Central Kazakhstan → Zhetysu → Upper Irtysh → Minusinsk.

The Alliance model is not invented later. It is inherited and reproduced at every node of the fan.

2.9 Summary

Sintashta matters twice over.

First, it crystallized the three pillars of power — horse, metal, dynasty — in an already multi-lineage milieu: some fifteen male lines in one cemetery, three large groups with different historical trajectories, a western Eurasian maternal pool. The model of the multi-lineage alliance is not invented later — it is inherited and institutionalized here.

Second, from it the fanwise dispersal began: eight parallel branches of R-Z93, differentiated already at the moment of crystallization, scatter across the post-Sintashta horizon, attested at some fifteen sites from Central Kazakhstan to Minusinsk, and each begins its own trajectory.

The configuration of horse, metal and inherited power proved a functional matrix to which steppe formations would return for centuries. And each time it met a new autochthonous society, one of the branches gave a local synthesis — inheriting the common matrix but rewritten for local conditions. The first and key such synthesis is the Orak-Ulus.

The fan has scattered. One of its branches — the one that will become the central trunk of this volume — moved east through the Kazakh steppes toward the Yenisei. There, in the mountain-enclosed Minusinsk Basin, a society awaited it that was itself a multi-component union, with a millennium’s experience of mutual integration. The Andronovans brought the horse, metal and the model of inherited power. The Okunev brought a millennium’s experience of exogamy and multi-lineage coexistence. What was born of their meeting is the subject of Chapter 3.

Conclusions

1. Sintashta (2100—1800 BCE) is one of the earliest nodes of the institutionalization of power in steppe Eurasia. The brevity of the active phase (about eighty years, three generations) points to crystallization — a phase transition at the coincidence of environment, structure and resources.

2. Kamennyi Ambar 5 is a multi-lineage alliance from the first day. Some fifteen male lines in three large groups (R1a in the majority, R1b in three clans with different fates, Okunev Q in two bearers). The Alliance component works from the very beginning; it is not formed later.

3. The central line R-Z93 is five to eight centuries older than Sintashta — inherited from the Corded Ware and Fatyanovo horizons of Eastern Europe. Sintashta did not engender it, but institutionalized it and at the same time spread it into eight parallel branches.

4. The three pillars converge into a single system: the horse (the DOM2 phenotype, synchronous with the horizon, in the role of an integration node rather than a ‘cradle’), metal (a specialized production embedded in the Circumpontic province), and dynasty (a narrow set of male lines alongside a broad western Eurasian maternal pool).

5. A fan of eight branches. By the moment of crystallization R-Z93 is already branched; the line central to the volume runs through the node R-S23592 (~2200) to the node R-YP1456 (~2100), whose splitting-off coincides with the heyday of Sintashta. The full passport of the branches and the canonical dates are in the Appendix to Chapter 2.

6. The post-Sintashta fan is documented by a palaeogenomic corpus across some fifteen sites from Central Kazakhstan to Minusinsk; the Zevakino cemetery is a late institutional analogue of Kamennyi Ambar.

7. DAEX at Sintashta is in embryonic form. The bond of the three pillars is the first archaeologically documented manifestation of the structure that the full DAEX model (Chapter 1) unfolds into four components.

8. The link with Chapter 3. The fan has scattered; one of the branches went east to the Yenisei — into the Minusinsk Basin, to the point of the Orak-Ulus Synthesis.

9. Epistemic status. The thesis that ‘Sintashta crystallized a multi-lineage alliance and launched the great fan’ is a strongly supported hypothesis: the palaeogenomic corpus records the facts (the diversity of Kamennyi Ambar, the post-Sintashta dispersal of daughter lines, the Fatyanovo pre-existence of R-Z93), while the institutional interpretation remains a step of reconstruction, open to refinement as the samples expand.

The Eight Macro-branches of R-Z93

The Sintashta phenomenon is not the invasion of a ready-made people, but the crystallization of a new social form out of the interaction of steppe and forest-steppe populations.

Purpose of the Appendix

This appendix contains the palaeogenetic corpus for the source node R-Z93 — the root biological point of the whole mainline of Volume I. The eight macro-branches of R-Z93, diverging from the Sintashta horizon around 2100 BCE, form a phylogenetic fan whose central branch (R-Z93 → R-Z2125 → R-S23592 → R-FGC56408 → R-YP1456) is traced in Chapter 3 (the Orak-Ulus Synthesis, sample I3391), Chapter 5 (the Sagsai horizon: I7033, I6363, ULI001) and Chapter 7 (the written fixation of the polity-name in the geography of Sagsai — the name is revealed there). The present appendix records the initial point of this biological axis. All the data have been verified through two independent primary sources: the public FTDNA Discover Haplotree and the aggregated aDNA database 2.07.40. The appendix remains within the horizon of Volume I; the later historical associations of individual branches are the material of the subsequent volumes of the series.

Three methodological safeguards run throughout the appendix.

(1) Anti-ethnicization. The figurative branch-names used in Chapter 2 (‘Indo-Aryan’, ‘Bashkir’, ‘Árpád’ and others) are navigational labels of the later historical traditions associated with the corresponding subclades, not assertions of ethnic continuity. A Y-subclade is not equal to an ethnos, a language or a culture; the R-Z93 macro-branch does not ‘carry’ ethnicity.

(2) Anti-biologization. The use of Y-chromosomal markers here is operational in character and does not imply that worldview models are biologically determined. The subclade designations distinguish demographic flows by their historical-geographical origin, nothing more.

(3) Anti-temporal-compression. The tracing of a branch across millennia does not mean the continuity of a people. Between the Sintashta horizon and any later tradition lie millennia with migrations, language shifts, political collapses and population restructurings.

BLOCK 1 · ANCESTRAL LINES

AND THE CONTROL COMPARISON OF R-Z93

The control comparison records that the R-Z93-descending subclades are absent in the Yamnaya and Central European Corded Ware samples, appear in the Poltavka (a single outlier), and crystallize in the Fatyanovo culture — 500—800 years before Sintashta. This localizes the biological root of the mainline in the forest-steppe Fatyanovo milieu, not in the steppe proper.
