As happened in many other Greek states, a tyrant arose in Athens in the 6th century B.C. His name was Peisistratos, and after several unsuccessful attempts he seized power in 546 B.C. and ruled until his death in 527, after which he was succeeded by his two sons, Hippias and Hipparchos.
Such tyrannies were a common feature of Greek political life as states made the transition from an aristocracy to either a democracy or an oligarchy. The Greek word τύραννος indicates that the individual seized or held power unconstitutionally but does not necessarily carry the negative force the word has today. Often the tyrant arose as the champion of the common people against the aristocracy.
Peisistratos, head of one of the large aristocratic families, seized power by force during a period of factional strife. Though many Athenians fled or were forced into exile (Herodotus 1.64), Aristotle's assessment of his tenure is positive:
Peisistratos' administration of the state was, as has been said, moderate, and more constitutional than tyrannic; he was kindly and mild in everything, and in particular he was merciful to offenders and moreover he advanced loans of money to the poor for their industries. (Athenian Constitution 16.1-2)
Aristotle has further praise for the tyrants, at least in their early days:
And in all other matters too he gave the multitude no trouble during his rule but always worked for peace and safeguarded tranquility; so that men were often to be heard saying that the tyranny of Peisistratos was the Golden Age of Kronos; for it came about later when his son succeeded him that the government became much harsher. And the greatest of all the things said of him was that he was popular and kindly in temper. For he was willing to administer everything according to the laws in all matters, never giving himself any advantage. ... Both the notables and the men of the people were most of them willing for him to govern, since he won over the former by his hospitality and the latter by his assistance in their private affairs and was good-natured to both. (Athenian Constitution 16.7-9)
That Peisistratid rule was surprisingly open is borne out by a fragment of a list of archons which shows that in 524 B.C. the future founder of democracy, Kleisthenes himself, held the chief magistracy while the tyrants were still in power, as did another rival aristocrat, Miltiades. For 599/1 B.C. we can read the name of the younger Peisistratos, grandson of the founder of the tyranny.
His reign, like that of so many tyrants, was characterized by large public works projects, the first in Athens for centuries. Large temples and altars were constructed for Zeus Olympios, Apollo Pythios, and the Twelve Gods. In addition, an extensive system of aqueducts and fountainhouses brought a reliable supply of good clean water into the city. The impact of this fine new water system is reflected in the fountainhouse scenes painted on dozens of black-figure hydrias (water jars) and other pots in the late 6th century.
Matters changed with the death of Peisistratos when his two sons Hippias and Hipparchos took over in 527 B.C. Aristotle describes the characters of the two brothers:
Affairs were now under the authority of Hipparchos and Hippias, owing to their station and their ages, but the government was controlled by Hippias, who was the elder and was statesmanlike and wise by nature; whereas Hipparchos was fond of amusement and lovemaking and had literary tastes; it was he who brought to Athens the poets such as Anakreon and Simonides, and the others.
