What was the name of the armistice that ended Ottoman participation in WWI?

The armistice that ended Ottoman participation in World War I was the Armistice of Mudros. It was signed on 30 October 1918 aboard the British battleship HMS Agamemnon in Mudros harbor on the Greek island of Lemnos.

The Ottoman representative was Rauf Bey, the minister of marine affairs; the Allies were represented by British Admiral Somerset Arthur Gough-Calthorpe. The agreement took effect at noon on 31 October and ended hostilities between the Ottoman Empire and the Allied powers in the Middle Eastern theater.

Its terms severely weakened the Ottoman state. Ottoman forces outside Anatolia had to surrender or withdraw, the army and navy were demobilized, and the Allies gained access to ports, railways, and strategic positions. They also received the right to occupy forts controlling the Dardanelles and Bosporus, and potentially other territories in cases of disorder.

Mudros was an armistice, not the final peace treaty. Allied occupation of Istanbul followed, and the punitive Treaty of Sèvres was signed in 1920 but never ratified by the Ottoman Parliament. After the Turkish War of Independence, the Treaty of Lausanne superseded the postwar settlement in 1923.
