russo-japanese war
日露戦争 にちろせんそう ルースカ・イポーンスカヤ・ヴァイナー
The Russo–Japanese War (1904–05) was fought between the Russian Empire and the Empire of Japan over territorial ambitions in Manchuria and Korea. Russia suffered a series of defeats, and lost a large portion of their navy at the Battle of Tsushima. The war ended in a peace treaty brokered by Theodore Roosevelt, which many in Japan felt did not contain favorable enough terms considering their military superiority. The war marked the emergence of Japan as a major world power, and one of the catalyst of the Russian revolution and subsequent civil war in 1917.
