Bey is originally a Turkish[1][2] word for "chieftain," traditionally applied to the leaders of small tribal groups. In historical accounts, many Turkish, other Turkic and Persian leaders are titled Bey, Beg or Beigh. They are all the same word with the simple meaning of "lord." The regions or provinces where Beys (the equivalent of Duke in Europe) ruled or which they administered were called Beylik, roughly meaning "Emirate" or "Principality" in the first case, "Province" or "Governorate" in the second (the equivalent of Duchy in Europe). Today, the word is used as a social title for men (like the English word "mister").
Turkish beys
The first three rulers of the Ottoman realm were titled Bey. The chief sovereign of the Ottoman Empire only came to be called Sultan starting in 1383 when Murad I was granted this title by the shadow Caliph in Cairo.
From 1776 until 1821, eight beys ruled Mani. These beys were Tzanetos Koutifaris (1776 - 1779), Mikhailbeis Troupakis or Mourtzinos (1779 - 1782), Tzanetbeis Kapetanakis Grigorakis (1782 - 1798), Panagiotis Koumoundouros (1798 - 1803), Antonbeis Grigorakis (1803 - 1808), Constantinos Zervakos or Zervobeis (1808 - 1810), Theodorobeis Grigorakis (1811 - 1815), and Petrobeis Mavromichalis (1815 - 1821). In 1792, after the Russians made a treaty with the Turks, Lampros Katsonis said, "Aikaterini [Catherine] did her treaty but Katsonis didn't do his treaty with the enemy. Katsonis, Androutsos, and Zacharias fought Ottomans in Porto Kagio."
