When Sunjong, the last emperor of the Korean Empire, died in April 1926, the Korean Communist Party and Cheondogyo planned a mass demonstration for his funeral, but the plan leaked. On 10 June students, including the Korean Students’ Science Study Society, scattered leaflets and cried "Manse" along the funeral route in Seoul.
It did not spread like the March First Movement, but students emerged as a force in the movement, and the drive for a single national party that followed laid the ground for the Singanhoe.
