The Russo-Japanese War ended in 1905 with the Treaty of Portsmouth, marking a significant turning point in global geopolitics. Japan's victory over Russia made it the first non-Western power to defeat a European empire in modern history, challenging prevailing notions of racial superiority and imperial dominance. This outcome shifted the balance of power in East Asia and established Japan as a formidable military force. The war and its aftermath also set the stage for future conflicts and political dynamics in the region.

The end of the Russo-Japanese War and the Treaty of Portsmouth inspired anti-imperial poets across Asia and Africa. This event challenged Eurocentric narratives and validated non-Western modernity, influencing global literary consciousness and encouraging poets to engage with themes of resistance and identity.
