Significance of the Russo-Japanese War:


The Russo-Japanese War held great international significance, as it was the first all-out war of the modern era in which a non-European power defeated one of Europe's great powers. As a result, the Russian Empire and Tsar Nicholas II lost considerable prestige, along with two of their three naval fleets. Popular outrage in Russia at the outcome helped lead to the Russian Revolution of 1905, a wave of unrest that lasted more than two years but did not manage to topple the tsar's government.

For the Japanese Empire, of course, victory in the Russo-Japanese War cemented its place as an up-and-coming great power, particularly since it came on the heels of Japan's victory in the First Sino-Japanese War of 1894-95. Nonetheless, public opinion in Japan was none too favorable. The Treaty of Portsmouth did not grant Japan either the territory or the monetary reparations that the Japanese people expected after their significant investment of energy and blood in the war.
