After the cries for Korean Independence on March 1, 1919, in what became known as the March 1st Movement, Japan shifted away from the predominantly military strategy that characterized the compulsory annexation of Korea in 1910 to a milder form of cultural control. It is likely that Japan recognized the need to change to a more detailed and rational rule within the Japanese Governor-General system in response to the resistance exhibited during the March 1st Movement. It was against this backdrop of a loosened cultural grasp on Korea that the most active and diverse periodicals of the colonization period, such as the Chosun Ilbo newspaper (March 5, 1920), the Dong-a-ilbo newspaper (April 1, 1920), and the magazine, The Dawn of Civilization, got their start.
