Ephialtes (Greek: Ἐφιάλτης , "Ephialtēs") was an ancient Athenian politician and an early leader of the democratic movement there.
 In the late 460s BC, he oversaw reforms that diminished the power of the Areopagus, a traditional bastion of conservatism, and which are considered by many modern historians to mark the beginning of the "radical democracy" for which Athens would become famous.
 These powers included the scrutiny and control of office holders, and the judicial functions in state trials.
 He introduced pay for public officeholders, reduced the property qualifications for holding a public office, and created a new definition of citizenship.
 Ephialtes, however, would not live to participate in this new form of government for long.
 In 461 BC, he was assassinated, probably at the instigation of resentful oligarchs, and the political leadership of Athens passed to his deputy, Pericles.

Pericles ( ; Greek: Περικλῆς "Periklēs", ] in Classical Attic; c. 495 – 429 BC) was a prominent and influential Greek statesman, orator and general of Athens during the Golden Age—specifically the time between the Persian and Peloponnesian wars.
 He was descended, through his mother, from the powerful and historically influential Alcmaeonid family.
Aeschines of Sphettus (Greek: Αἰσχίνης Σφήττιος ) or Aeschines Socraticus (sometimes but now rarely written as "Aischines" or "Æschines"; c. 425 BC – c. 350 BC), son of Lysanias, of the deme Sphettus of Athens, was in his youth a follower of Socrates.
 Historians call him Aeschines Socraticus—"the Socratic Aeschines"—to distinguish him from the more historically influential Athenian orator also named Aeschines.

The House of Ögedei, sometimes called the Ögedeids, were an influential family of Mongol Borjigin (Imperial, or Golden Family) from the 12th to 14th centuries.
 They were descended from Ögedei Khan (1186-1241), a son of Genghis Khan who had become his father's successor, second Khagan of the Mongol Empire.
 Ögedei continued the expansion of the Mongol Empire.
 When, after the Toluid Möngke Khan's death, the Mongol Empire disintegrated into civil war, the members of the House of Ogedei were influential players in the politics of the region.
 Of Genghis Khan's sons — Ogedei, Jochi, Chagatai, and Tolui — the House of Ögedei tended to ally with the Chagataids (descendants of Chagatai) against the House of Jochi, while seeking control for themselves within the Chagatai Khanate at first.
 The Ogedeids also allied with the Golden Horde against the Yuan emperor Kublai Khan (son of Tolui), who was allied with his brother Hulagu, leader of the Ilkhanate in Persia.
 The Ogedeids attempted to unite the Mongol Empire under their own rule, and Ogedeid princes continued to march against the Yuan dynasty well into the 14th century such as during the Kaidu–Kublai war.
The Barmakids (Persian: برمکیان‎ ‎ "Barmakīyān"; Arabic: البرامكة‎ ‎ "al-Barāmikah", from the Sanskrit प्रमुख "pramukha", "leader, chief administrator, registrar"); also spelled Barmecides, were an Iranian influential family from Balkh in Bactria where they were originally hereditary Buddhist leaders (in the Nawbahar monastery), and subsequently came to great political power under the Abbasid caliphs of Baghdad.
 Khalid, the son of Barmak became the prime minister ("wazir") of Al Saffah, the first Caliph of the Abbasid dynasty.
 His son Yahya aided Harun Al-Rashid in capturing the throne and rose to power as the most powerful man in the Caliphate.
 The Barmakids were remarkable for their majesty, splendor and hospitality.
 They are mentioned in some stories of the "Arabian Nights".
