Russo-Japanese War

The Russo-Japanese War (1904-1905) was a conflict between Russia and Japan primarily over rival imperial ambitions in East Asia, particularly Korea and Manchuria. Japan sought to expand its influence, while Russia aimed to secure its territory and interests. The war marked a significant shift in global power dynamics, as Japan emerged as a modern military force, defeating the much larger Russian Empire. The conflict concluded with the Treaty of Portsmouth, mediated by the United States, establishing Japan as a respected world power and signaling the decline of Russian influence in the region.
