李大钊
A demonstration was organized in front of the Tiananmen Gate on March 18. Li Dazhao, the leader of the demonstrators, made an emotional address. He called for an end to all unequal treaties signed between China and the foreign powers, in addition to expelling foreign ambassadors who issued the ultimatum. The Nationalist army, which was based in Guangzhou at the time, was urged to confront possible imperialist incursions since the Beiyang Government was unwilling to.
