Why did turkey enter world war 1?

Answer 1

Turkey entered the WW I on the side of Central powers. Turkish forces repelled a joint naval and ground attack by British and French forces in what is known now as Battle of Gallipoli. During the war the Armenian population of Turkey was subjected to so-called relocation which resulted in deaths of around 300,000 to 1500,000 Armenians. Ottoman state was partitioned by allied powers after the war through the Treaty of Sevres. Mustafa Kemal Pasha led a Turkish National Movement against occupying allied forces in Constantinople and Smyrna. After the WW I the Republic of Turkey emerged as the successor of Ottoman empire.
