In 1917 China declared war on Germany in the hope of recovering its lost province, then under Japanese control. On 4 May 1919, there were massive student demonstrations against the Beijing government and Japan. The political fervor, student activism and iconoclastic and reformist intellectual currents set in motion by the patriotic student protest developed into a national awakening known as the May Fourth Movement. The intellectual milieu in which the May Fourth Movement developed was known as the New Culture Movement and occupied the period 1917-1923. The student demonstrations of 4 May 1919, were the high point of the New Culture Movement, and the terms are often used synonymously. Chinese representatives refused to sign the Treaty of Versailles due to intense pressure from both the student protesters and public opinion.
