The San Francisco Peace Treaty was signed on September 8, 1951, officially ending the state of war between Japan and the Allied Powers after World War II. It marked Japan's renunciation of militarism and established its sovereignty, while also outlining reparations and territorial adjustments. The treaty was signed by 48 nations, excluding the Soviet Union and several other countries. The treaty played a crucial role in shaping post-war relations in the Asia-Pacific region. It allowed Japan to rebuild its economy and re-enter the international community, while also laying the groundwork for future alliances, particularly with the United States, during the Cold War era.
