The Russo-Japanese War was a military conflict fought between the Russian Empire and the Empire of Japan from 1904 to 1905. Much of the fighting took place in what is now northeastern China. The Russo-Japanese War was also a naval conflict, with ships exchanging fire in the waters surrounding the Korean peninsula. The brutal conflict in the western Pacific changed the balance of power in Asia and set the stage for World War I.
Although tensions in the region were far from over, the Russo-Japanese War did shift the balance of global power, marking the first time in modern history that an Asian nation had defeated a European one in military combat. It would also mark the beginning of warfare involving world powers in the Pacific region.
Hope this helps:)
