The Caucasus Campaign was a series of military operations during World War I, primarily fought between the Ottoman Empire and the Russian Empire. It took place from 1914 to 1917 in the mountainous region of the Caucasus, which includes present-day countries like Georgia, Armenia, and Azerbaijan. The campaign aimed to secure strategic territories and control vital supply routes. The conflict involved several key battles, including the Battle of Sarikamish and the Battle of Baku. The harsh terrain and weather conditions posed significant challenges for both sides. Ultimately, the campaign ended with the collapse of the Russian Empire in 1917, leading to a shift in control over the region.
