The Gallipoli campaign, which commenced in April 1915, represented a major strategic effort by British Empire and French forces to seize control of the Dardanelles. The primary objective of this ambitious naval and land operation was to secure a maritime route to Russia, capture the Ottoman capital of Constantinople, and ultimately force the Ottoman Empire to withdraw from the First World War.

Despite the initial strategic intent, the campaign rapidly descended into a brutal stalemate. Allied troops faced formidable terrain and fierce resistance from Ottoman defenders, leading to months of static trench warfare that mirrored the conditions on the Western Front. The logistical challenges and the inability to break through the defensive lines resulted in mounting casualties and a growing realisation that the operation was unlikely to achieve its intended goals.

The campaign was eventually abandoned, with Allied forces completing a successful evacuation by early 1916. The operation is remembered as a costly failure that had profound consequences for the participating nations:

• The significant loss of life among British, French, and colonial troops.
• The emergence of a powerful national identity in Australia and New Zealand, often referred to as the Anzac spirit.
• The reinforcement of Turkish national pride and military prestige under the leadership of figures such as Mustafa Kemal.
• The strategic shift in the Mediterranean theatre of the war.

In the decades that followed, the legacy of Gallipoli became deeply embedded in the collective memory of the nations involved. For the United Kingdom, France, and their allies, it remains a sombre reminder of the immense human cost of the conflict. Conversely, for Turkey, the defence of the peninsula is celebrated as a pivotal moment in the nation's history, marking a successful stand against foreign intervention.
