The May Fourth Movement was an anti-imperialist, cultural, and political movement growing out of student demonstrations in Beijing on May 4, 1919, protesting against the Chinese government's weak response to the Treaty of Versailles, especially allowing Japan to receive territories in Shandong which had been surrendered by Germany after the Siege of Tsingtao. These demonstrations sparked national protests and marked the upsurge of Chinese nationalism, a shift towards political mobilization and away from cultural activities, and a move towards a populist base rather than intellectual elites. Many political and social leaders of the next decades emerged at this time.
