include (wealthy, male) foreign citizens in Athenian society. He also established sortition – the random selection of citizens to fill government positions rather than kinship or heredity. It is also speculated that, in another move to lower the barriers of kinship and heredity when it comes to participation in Athenian society, Cleisthenes made it so foreign residents of Athens were eligible to become legally privileged. In addition, he reorganized the Boule, created with 400 members under Solon, so that it had 500 members, 50 from each tribe. He also introduced the bouletic oath, "To advise according to the laws what was best for the people". The court system (Dikasteria – law courts) was reorganized and had from 201–5001 jurors selected each day, up to 500 from each tribe. It was the role of the Boule to propose laws to the assembly of voters, who convened in Athens around forty times a year for this purpose. The bills proposed could be rejected, passed or returned for amendments by the assembly. Introduction of Ostracism Cleisthenes also may have introduced ostracism (first used in 487 BC), whereby a vote by at least 6,000 citizens would exile a citizen for ten years. The initial and intended purpose was to vote for a citizen deemed to be a threat to the democracy, most likely anyone who seemed to have ambitions to set himself up as tyrant. However, soon after, any citizen judged to have too much power in the city tended to be targeted for exile (e.g., Xanthippus in 485–84 BC). Under this system, the exiled man's property was maintained, but he was not physically in the city where he could possibly create a new tyranny. One later ancient author records that Cleisthenes himself was the first person to be ostracized. Cleisthenes called these reforms isonomia ("equality vis à vis law", iso- meaning equality; nomos meaning law), instead of demokratia. Cleisthenes' life after his reforms is unknown as no ancient texts mention him thereafter. Attempt to obtain Persian support In 507 BC, during the time Cleisthenes was leading Athenian politics, and probably at his instigation, democratic Athens sent an embassy to Artaphernes, brother of Darius I, and Achaemenid Satrap, of Asia Minor in the capital of Sardis, looking for Persian assistance in order to resist the threats from Sparta. Herodotus reports that Artaphernes had no previous knowledge of the Athenians, and his initial reaction was
