Step-by-step explanation:
In February 1904, the Russo-Japanese War began, which was a significant conflict between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and Korea. This war marked the rise of Japan as a major world power and highlighted the need for change within the Russian government due to military defeats.
The conflict was sparked by Russia's occupation of Manchuria in 1900 and their subsequent clash with Japanese interests. One of the most notable events was the Battle of Port Arthur, where the Japanese navy launched a surprise attack and severely damaged the Russian Pacific fleet. The battle was pivotal and set the stage for further Japanese victories.
This year was also characterized by the growing tension and dissatisfaction with the Tsarist regime, as demonstrated by a peaceful protest that was held outside the Tsar's Winter Palace in St. Petersburg in January 1905, an event that became a precursor to the Russian Revolution.
