Winston Churchill had a varied career during the First World War. At the outbreak of war in 1914, Churchill was serving as First Lord of the Admiralty. In 1915 he helped orchestrate the disastrous Dardanelles naval campaign and was also involved in the planning of the military landings on Gallipoli, both of which saw large losses.

Following the failure of these campaigns, Churchill was demoted and resigned from government. He became an officer in the Army and served on the Western Front until early 1916.

In 1917, under Prime Minister David Lloyd George’s coalition government, Churchill was appointed Minister of Munitions, a position he held until January 1919.

In 1919, shortly after the end of the war, he was appointed Secretary of State for Air and War. In this role he attended peace talks in Paris in 1919. He was not involved in the peace process itself but took part in discussions about the shape of the post-war world. He held this position until 1921.
