Britain and France Declare War on Russia
Tensions over influence in the Ottoman Empire and the Eastern Question escalated after Russia's victory at the Battle of Sinop in late 1853. Britain and France, seeking to curb Russian expansion and protect their strategic interests in the Black Sea region, issued an ultimatum that Russia ignored. On March 28, 1854, Britain formally declared war, with France following suit shortly thereafter. This alliance with the Ottoman Empire and later Sardinia transformed a regional conflict into a broader European war. The declarations committed major powers to a prolonged campaign focused on the Crimean Peninsula. Naval and land operations soon followed.
