Cleisthenes

Cleisthenes was born around 565 BCE into the Alcmaeonid family, one of the oldest and wealthiest aristocratic houses in Athens ^[1]. His father was Megacles, a leading figure in Athenian factional politics, and his mother was Agariste, daughter of Cleisthenes of Sicyon, the tyrant after whom the boy was named ^[2]. Herodotus records the famous story of Agariste's betrothal: the Sicyonian tyrant hosted suitors from across the Greek world for a year before choosing Megacles, a match that tied the Alcmaeonids to one of the most powerful courts in the Peloponnese ^[2].

The family carried a burden alongside its wealth. Two generations earlier, an Alcmaeonid archon named Megacles had ordered the killing of the followers of Cylon, a failed coup leader, after they had taken sanctuary at an altar. The sacrilege produced a hereditary curse, and the Alcmaeonids were periodically expelled from Athens because of it ^[1]. Cleisthenes grew up under this cloud, and his rivals would invoke the curse against him throughout his career ^[3].

His childhood coincided with the rise of Peisistratus, who seized power as tyrant of Athens in the middle of the sixth century. The relationship between the tyrant and the Alcmaeonids shifted between alliance and open hostility. Megacles at one point helped restore Peisistratus and married his daughter to him, then broke with him again, and the family spent long stretches in exile as a result ^[1]. These reversals shaped the political world in which Cleisthenes came of age: a city where a handful of noble clans competed for dominance and the mass of citizens counted for little.

Despite his family's uneasy standing, Cleisthenes held high office under the tyranny. An inscribed fragment of the Athenian archon list shows that he served as eponymous archon in 525 to 524 BCE, during the rule of Hippias, son of Peisistratus ^[4]. The discovery of this fragment surprised scholars, since Herodotus had implied the Alcmaeonids spent the whole tyranny in exile. It suggests instead that the family cooperated with the regime for a time before the final break ^[4].

That break came after 514 BCE, when the murder of Hipparchus, brother of Hippias, made the tyranny harsher and more suspicious. The Alcmaeonids, now in exile again, worked to bring the regime down from outside. According to Herodotus they rebuilt the burned temple of Apollo at Delphi more splendidly than their contract required, and in return the oracle repeatedly told Spartan envoys to free Athens ^[2]. The pressure worked. In 510 BCE the Spartan king Cleomenes marched into Attica, besieged the tyrant's family, and forced Hippias into exile ^[1].

The fall of the tyranny reopened the old contest between noble factions. Cleisthenes faced a rival named Isagoras, who won election as archon for 508 to 507 BCE with support from other aristocrats ^[3]. Losing that round, Cleisthenes made a move that Herodotus describes in a single striking phrase: he took the people into his faction ^[2]. By promising the ordinary citizens of Athens a real share in political power, he built a base of support no other aristocrat could match, and the proposals he put before them became the blueprint for a new kind of state.

Isagoras answered by calling in foreign help. He appealed to Cleomenes of Sparta, who sent a herald demanding the expulsion of the accursed, a pointed reference to the old Alcmaeonid sacrilege ^[2]. Cleisthenes withdrew from the city, and Cleomenes arrived with a small force, expelled seven hundred Athenian households named by Isagoras, and attempted to dissolve the council and hand power to three hundred of Isagoras's partisans ^[3].

The attempt collapsed in spectacular fashion. The council resisted, the Athenian people rose up, and Cleomenes, Isagoras, and their supporters were trapped on the Acropolis. After a siege of two days the Spartans surrendered under truce and left Attica, while many of Isagoras's followers were executed ^[2]. The Athenians then recalled Cleisthenes and the exiled families, and his reform program went forward with the full backing of a citizen body that had just defended it in the streets ^[3].

Historians have long debated the exact sequence of these events, since Herodotus and the later Aristotelian Constitution of the Athenians differ on whether the reforms were enacted before or after the Spartan intervention ^[5]. What is not in doubt is the outcome. By 507 BCE Cleisthenes was the dominant figure in Athens and his new institutions were law.

Any account of Cleisthenes achievements begins with the reorganization of the citizen body. He abolished the political role of the four old Ionian tribes, which had been dominated by clan and cult loyalties, and created ten new tribes, each named after an Attic hero ^[5]. Every tribe was assembled from three regional sections called trittyes, one drawn from the city, one from the coast, and one from the inland plain. The effect was deliberate: no tribe corresponded to a regional power base, so no aristocrat could mobilize a bloc of neighbors and dependents as the old factions had done ^[1].

The foundation of the system was the deme, the local village or city ward. Cleisthenes made membership in a deme, recorded on its register, the basis of citizenship itself. Athenians were now formally identified by their demotic, their deme name, rather than solely by their father's name, a change ancient writers connected to weakening the prestige of noble descent ^[5]. There were roughly 139 demes, and deme membership was hereditary, so the structure endured for centuries.

On this base he built the Council of Five Hundred, or boule, with fifty members chosen by lot from each tribe every year. The council prepared business for the assembly, oversaw magistrates, and gave thousands of ordinary citizens direct experience of government over time ^[6]. The ten tribes also became the framework for the army, each supplying a regiment, and later for the board of ten generals. Ancient tradition additionally credited Cleisthenes with inventing ostracism, the procedure by which the assembly could vote to exile a citizen for ten years without confiscating his property, although the first recorded ostracism did not occur until 487 BCE and some scholars question the attribution ^[5]. Contemporaries did not yet call the new order demokratia. The watchword associated with it was isonomia, equality under the law, and Herodotus uses that term when he credits the reforms with making Athens strong ^[2].

Almost nothing survives about the private life of Cleisthenes, a silence typical for Greek public figures of the sixth century. No ancient source names a wife or children, and no anecdotes about his household, habits, or appearance were preserved ^[1]. What the record does show is the density of his family connections. Through his mother he was the grandson of a Sicyonian tyrant, and through the wider Alcmaeonid line he was related to figures who dominated Athenian politics for the next century ^[3].

Those connections mattered long after his death. His niece Agariste, named for his mother, married Xanthippus and became the mother of Pericles, the statesman who presided over the radical democracy of the mid fifth century ^[2]. The philosopher-adjacent aristocrat Alcibiades also descended from the Alcmaeonids on his mother's side. Ancient Athenians were fully aware of the irony that their democracy owed its structure to a man from one of the proudest noble houses in Greece ^[1].

The family curse never quite released its grip. As late as 432 BCE, on the eve of the Peloponnesian War, Sparta demanded that Athens drive out the accursed, a diplomatic jab aimed at Pericles through his Alcmaeonid ancestry ^[7]. That the taint could still be weaponized two generations later is a measure of how deeply hereditary reputation ran in Greek politics, and of how remarkable it was that Cleisthenes converted that liability into leadership of a popular movement.

Cleisthenes vanishes from the historical record soon after his reforms took effect, and the manner of his disappearance is one of the puzzles of Athenian history. Herodotus, our fullest source for the crisis of 508 to 507 BCE, simply stops mentioning him ^[2]. One episode from around 507 BCE may bear on his eclipse: Athenian envoys sent to the Persian satrap at Sardis to seek an alliance against Sparta agreed to give earth and water, the tokens of submission to the Persian king. The envoys were repudiated when they returned home, and some historians suspect the embarrassment damaged Cleisthenes, who was the leading figure when the embassy was dispatched ^[3].

No ancient author records his death, his burial, or any final office. The tradition placing his death around 492 BCE rests on inference rather than testimony, and estimates of his lifespan, from roughly 565 BCE to about 492 BCE, are modern reconstructions from the known dates of his career ^[1]. Unlike later democratic heroes he received no known cult, statue, or public tomb in the classical period, a quiet ending for the man whose system every Athenian citizen inhabited daily.

The institutions outlived their author without interruption. The tribes, demes, and council he created were still functioning when Athens faced the Persian invasions of 490 and 480 BCE, and the citizen army that fought at Marathon was organized by his ten tribal regiments ^[6]. Whatever happened to Cleisthenes personally, the machinery he built passed its first great tests within a generation.

Later Athenians looked back on Cleisthenes as a founder. The Aristotelian Constitution of the Athenians treats his reforms as a decisive stage in the growth of the democracy, more far-reaching than Solon's earlier laws because they rebuilt the citizen body itself ^[5]. Fourth century orators and the democracy's own official memory folded him into a lineage of lawgivers, even as popular tradition often gave more credit to the tyrannicides Harmodius and Aristogeiton, whose statues stood in the agora while Cleisthenes had none ^[3].

Modern historians generally regard the reforms of 508 to 507 BCE as the birth of Athenian democracy in an institutional sense, even though the word demokratia came into use later and further reforms under Ephialtes and Pericles deepened popular power ^[6]. In 1993 numerous institutions marked the 2,500th anniversary of the reforms, and scholarly conferences and publications on the origins of democracy took Cleisthenes as their starting point ^[6]. Debate continues over his motives: a genuine democrat, a calculating aristocrat who armed the people against his rivals, or something in between. Herodotus himself hints at the second reading, while noting that the result was a stronger Athens ^[2].

The basic Cleisthenes facts are secure regardless of how one judges his intentions. He redrew the map of citizenship, replaced loyalty to clan with loyalty to the polis, created a council open to ordinary men, and left a structure durable enough to carry Athens through invasion, war, and empire. Any Cleisthenes biography must end on that point: few politicians in any age have designed institutions that outlasted them by so long, or been so thoroughly overshadowed by their own creation.
