1936年2月21日深夜,在乌兰察布草原重镇百灵庙打响了蒙政会保安队爱国官兵反对德王投日,参加抗日的枪声。这就是内蒙古近代史上震惊全国“的百灵庙军事暴动”。辛亥革命后建立的北洋政府和国民政府,对蒙古族人民实行大汉族主义的民族压迫政策,继续开垦蒙荒,设省置县,剥夺蒙旗权 Late at night on February 21, 1936, the patriotic officers and men of the Mongolian government security team were fired at the Bailingmiao, a grassland town in Wulanchabu, against German King Vil Day and joining in the gunshots of resistance against Japan. This is the “Beringling military riot” that shocked the whole country in recent history in Inner Mongolia. The Beiyang government and the national government established after the 1911 Revolution carried out the Han nationalist oppression policy toward the Mongolian people and continued to reclaim the wasteland.
