A crisis in what country in 1905 nearly led to a war?

The crisis in Russia in 1905, known as the Russian Revolution of 1905, was marked by widespread unrest, strikes, and demands for political reform. The situation was exacerbated by Russia's defeat in the Russo-Japanese War, leading to significant internal turmoil. The crisis nearly escalated into a war with Japan as tensions remained high over territorial disputes in East Asia. This period highlighted Russia's declining influence and contributed to the eventual upheaval in the following years.
