The Pact of Halepa (Greek: Σύμβαση της Χαλέπας) or Halepa Charter (Χάρτης της Χαλέπας) was an agreement made in 1878[1] between the Ottoman Empire (then ruled by the Sultan Abdul Hamid II) and the representatives of the Cretan Revolutionary Committee, which secured wide-ranging autonomy for the island of Crete.
Following the Russo-Turkish War of 1877–78 and the Treaty of Berlin (1878), the Ottoman government pledged to carry out reforms in the Empire's administration to remove discrimination against the Christian population.
More recently, since 1875, the island had been again in a state of revolt, and a revolutionary committee of leading Christian Cretans had been formed.
This he did, working closely with the British Ambassador who was able to exercise considerable influence over the Ottoman government.
