What was the gallipoli campaign and why was it so important

Hmph..The Gallipoli Campaign of 1915-16, also known as the Battle of Gallipoli or the Dardanelles Campaign, was an unsuccessful attempt by the Allied Powers to control the sea route from Europe to Russia during World War I...It was the battle that changed the course of the First World War. Fought over 36 hours on May 31 1916, the Battle of Jutland was the only major battle of the war fought at sea, but became known as perhaps the largest surface battle in naval history due to the numbers of battleships and battlecruisers engaged..

Love, grace..-
