Concluded on 30 October 1918 and taking effect at noon the next day, the Armistice of Mudros (Turkish: Mondros Mtarekesi) ended hostilities in the Middle Eastern theatre between the Ottoman Empire and the Allies of World War I. It was signed by the Ottoman Minister of Marine Affairs Rauf Bey and British Admiral Somerset Arthur Gough-Calthorpe, on board HMS Agamemnon in Moudros harbor on the Greek island of Lemnos.Among its conditions, the Ottomans surrendered their remaining garrisons outside Anatolia, granted the Allies the right to occupy forts controlling the Straits of the Dardanelles and the Bosporus, and to occupy any Ottoman territory "in case of disorder" threatening their security. The Ottoman Army (including the Ottoman Air Force) was demobilized; and all ports, railways and other strategic points were made available for use by the Allies. In the Caucasus, the Ottomans had to retreat to within the pre-war borders between the Ottoman and the Russian Empires.

The armistice was followed by the occupation of Constantinople (Istanbul) and the subsequent partitioning of the Ottoman Empire. The Treaty of Svres (10 August 1920), which was signed in the aftermath of World War I, imposed harsh terms on the Ottoman Empire, but it was never ratified by the Ottoman Parliament in Istanbul. The Ottoman Parliament was officially disbanded by the Allies on 11 April 1920 due to the overwhelming opposition of the Turkish MPs to the provisions discussed in Svres. Afterward, the Turkish War of Independence was fought from 1919 to 1923. The Grand National Assembly of Turkey, established in Ankara on 23 April 1920 by Mustafa Kemal Pasha and his followers (including former MPs of the closed Ottoman Parliament), became the new de facto government of Turkey. The Armistice of Mudros was superseded by the Treaty of Lausanne, signed on 24 July 1923, following the Turkish victory in the War of Independence.



The Ottoman Empire (; Ottoman Turkish: دولت عليه عثمانيه Devlet-i ʿAlīye-i ʿOsmānīye, lit. 'The Sublime Ottoman State'; Turkish: Osmanlı İmparatorluğu or Osmanlı Devleti; French: Empire ottoman) was an empire that controlled much of Southeastern Europe, Western Asia, and Northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed the Conqueror.Under the reign of Suleiman the Magnificent, the Ottoman Empire marked the peak of its power and prosperity, as well as the highest development of its governmental, social, and economic systems. At the beginning of the 17th century, the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the Ottoman Empire, while others were granted various types of autonomy over the course of centuries. With Constantinople (modern-day Istanbul) as its capital and control of lands around the Mediterranean Basin, the Ottoman Empire was at the centre of interactions between the Middle East and Europe for six centuries.

While the empire was once thought to have entered a period of decline following the death of Suleiman the Magnificent, this view is no longer supported by the majority of academic historians. The newer academic consensus posits that the empire continued to maintain a flexible and strong economy, society and military throughout the 17th and for much of the 18th century. However, during a long period of peace from 1740 to 1768, the Ottoman military system fell behind that of their European rivals, the Habsburg and Russian empires. The Ottomans consequently suffered severe military defeats in the late 18th and early 19th centuries. The successful Greek War of Independence concluded with decolonization of Greece following the London Protocol (1830) and Treaty of Constantinople (1832). This & other defeats prompted the Ottoman state to initiate a comprehensive process of reform and modernization known as the Tanzimat. Thus, over the course of the 19th century, the Ottoman state became vastly more powerful and organized internally, despite suffering further territorial losses, especially in the Balkans, where a number of new states emerged.The Committee of Union and Progress (CUP) established the Second Constitutional Era in the Young Turk Revolution in 1908, turning the Empire into a constitutional monarchy, which conducted competitive multi-party elections. However, after the disastrous Balkan Wars, the now radicalized and nationalistic CUP took over the government in the 1913 coup d'état, creating a one party regime. The CUP allied the Empire with Germany hoping to escape from the diplomatic isolation which had contributed to its recent territorial losses, and thus joined World War I on the side of the Central Powers. While the Empire was able to largely hold its own during the conflict, it was struggling with internal dissent, especially with the Arab Revolt in its Arabian holdings. During this time, genocide was committed by the Ottoman government against the Armenians, Assyrians, and Greeks. The Empire's defeat and the occupation of part of its territory by the Allied Powers in the aftermath of World War I resulted in its partitioning and the loss of its Middle Eastern territories, which were divided between the United Kingdom and France. The successful Turkish War of Independence, led by Mustafa Kemal Atatürk against the occupying Allies, led to the emergence of the Republic of Turkey in the Anatolian heartland and the abolition of the Ottoman monarchy.
