The Fourth Crusade of 1202-4 brought Venetian rule to Crete. The Venetians established the Kingdom of Candia on the island. In 1669 the Ottomans conquered Crete, leaving the Ionian Islands as the only Greek territory not to be ruled by Ottomans.
Greece's independence in 1829 inspired the Greek majority in Crete to wish for a unification of the island with the newly established nation state. By that time 80% of Crete's population was Christian Greek. The remainder consisted primarily of Greeks that had converted to Islam, and some immigrated Turks.
In 1897 a revolt broke out on the island which was violently crushed by the Ottoman authorities. The Great Powers, Britain, France, Italy and Russia, decided to occupy Crete to restore order. As unification with Greece was not desired by the Great Powers, the Cretan State was founded in 1898 which was nominally under Ottoman suzerainty but effectively under allied control.

Flag of the Cretan State
The son of King George of Greece, Prince George, became the first High Commissioner of the Cretan State. In 1907 a new revolt broke out over the question of unification. In 1908 Crete was unified with Greece, but it took until 1913 before it was made official. As a result most Cretan Muslims, many of them Greek, left the island for other parts of the Ottoman Empire. This history affected the way Greeks and Turks dealt with Cyprus in the decades to follow, with Turkey intervening in 1974 to protect the Turkish Cypriots from a likely unification with Greece compromising their safety and identity.
Currency and coins
The Cretan State had its owm Drachma, at par with the Greek Drachma and the Latin Monetary Union. Coins were only issued in 1900 and 1901 and were minted at the Monnaie de Paris.
The Cretan silver coins depict Prince George, High Commissioner of Crete. He is not to be confused with his father George who was King of Greece.
