Hipparchus (son of Peisistratos) in the context of "Peisistratos"

Pisistratus (also spelled Peisistratus or Peisistratos; Ancient Greek: Πεισίστρατος Peisistratos; c. 600 BC – 527 BC) was a politician in ancient Athens, ruling as tyrant in the late 560s, the early 550s and from 546 BC until his death. His unification of Attica, the triangular peninsula of Greece containing Athens, along with economic and cultural improvements laid the groundwork for the later pre-eminence of Athens in ancient Greece. His legacy lies primarily in his institution of the Panathenaic Games, historically assigned the date of 566 BC, and the consequent first attempt at producing a definitive version of the Homeric epics. Pisistratus's championing of the lower class of Athens is an early example of populism. While in power, he did not hesitate to confront the aristocracy and greatly reduce their privileges, confiscating their lands and giving them to the poor. Pisistratus funded many religious and artistic programs, in order to improve the economy and spread the wealth more equally among the Athenian people.

Pisistratids is the common family or clan name for the three tyrants, who ruled in Athens from 546 to 510 BC, referring to Pisistratus and his two sons, Hipparchus and Hippias.
