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

Isagoras (Ancient Greek: Ἰσαγόρας), son of Tisander, was an Athenian aristocrat in the late 6th century BC.

He had remained in Athens during the tyranny of Hippias, but after Hippias was overthrown, he became involved in a struggle for power with Cleisthenes, a fellow aristocrat. In 508 BC he was elected archon eponymous, but Cleisthenes opposed him, with support from the majority of the population. Isagoras requested support from the Spartan king Cleomenes I, an old friend who had earlier been given hospitality by Isagoras. According to Herodotus, Cleomenes had had an affair with Isagoras's wife.

The Greco-Persian Wars (also often called the Persian Wars) were a series of conflicts between the Achaemenid Empire and Greek city-states that started in 499 BC and lasted until 449 BC. The collision between the fractious political world of the Greeks and the enormous empire of the Persians began when Cyrus the Great conquered the Greek-inhabited region of Ionia in 547 BC. Struggling to control the independent-minded cities of Ionia, the Persians appointed tyrants to rule each of them. This would prove to be the source of much trouble for the Greeks and Persians alike.

In 499 BC, the tyrant of Miletus, Aristagoras, embarked on an expedition to conquer the island of Naxos, with Persian support; however, the expedition was a debacle and, preempting his dismissal, Aristagoras incited all of Hellenic Asia Minor into rebellion against the Persians. This was the beginning of the Ionian Revolt, which would last until 493 BC, progressively drawing more regions of Asia Minor into the conflict. Aristagoras secured military support from Athens and Eretria, and in 498 BC these forces helped to capture and burn the Persian regional capital of Sardis. The Persian king Darius the Great vowed to have revenge on Athens and Eretria for this act. The revolt continued, with the two sides effectively stalemated throughout 497–495 BC. In 494 BC, the Persians regrouped and attacked the epicenter of the revolt in Miletus. At the Battle of Lade, the Ionians suffered a decisive defeat, and the rebellion collapsed, with the final embers being stamped out the following year.

The Thirty Tyrants (Ancient Greek: οἱ τριάκοντα τύραννοι, hoi triákonta týrannoi) were an oligarchy that briefly ruled Athens from 404 BCE to 403 BCE. Installed into power by the Spartans after the Athenian surrender in the Peloponnesian War, the Thirty became known for their tyrannical rule, first being called "The Thirty Tyrants" by Polycrates. Although they maintained power for only eight months, their reign resulted in the killing of 5% of the Athenian population, the confiscation of citizens' property, and the exile of other democratic supporters.

The Alcmaeonidae (/ˌælkmiːˈɒnɪdiː/; Ancient Greek: Ἀλκμαιωνίδαι, Alkmaionidai; Attic: Ἀλκμεωνίδαι, Alkmeonidai) or Alcmaeonids (/ˌælkmiːˈoʊnɪdz/) were a wealthy and powerful noble family of ancient Athens, a branch of the Neleides who claimed descent from the mythological Alcmaeon, the great-grandson of Nestor.

In the 7th to late 5th centuries BC, the Alcmaeonidae played a significant role in the developments and events that occurred in Athens. Such developments included overthrowing an Athenian tyrant, helping to lay the foundations of Athenian democracy, and having generals for Athens during the Peloponnesian War. The Alcmaeonidae were mentioned frequently throughout Herodotus' The Histories, and many played a key role in shaping Athens. The first prominent Alcmaeonid was Megacles, who was exiled from the city and given a curse on him and his family. Furthermore, there was Cleisthenes, who became known as "the father of Athenian democracy" by numerous scholars and historians. Another famous Alcmaeonid was Pericles, whom Thucydides would later call "the first citizen of Athens," as well as Alcibiades, who switched sides numerous times during the Peloponnesian War, and would end up being the last of the notable Alcmaeonidae. The main aristocratic rival of the Alcmaeonidae in the 6th and 5th centuries BC were the Peisistratids.

Hippias (Ancient Greek: Ἱππίας, romanized: Hippías; c. 570 BC – 490 BC) was the last tyrant of Athens, ruling from 527 to 510 BC. He was one of the Peisistratids, a group of tyrants from the same family in ancient Greece. His father was Pisistratus, who preceded him as ruler of Athens, while his brother Hipparchus may have ruled jointly with him. Hippias also had an illegitimate son, Hegesistratus, whom he made tyrant of Sigeion. He was deposed when Cleomenes I of Sparta successfully invaded Athens and forced him to flee to the Achaemenid Empire.

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.

Ostracism (Greek: ὀστρακισμός, ostrakismos) was an Athenian democratic procedure in which any citizen could be expelled from the city-state of Athens for ten years. While some instances clearly expressed popular anger at the citizen, ostracism was often used preemptively as a way of neutralizing someone thought to be a threat to the state or a potential tyrant. The word ostracism continues to be used for various forms of shunning.
