Today marks 155 years since the uprising that established the Paris Commune.

Before May Day became the international day to celebrate labor struggles, workers and other rebels observed March 18, the anniversary of the beginning of the Paris Commune in 1871.

For example, on March 18, 1877, the young Peter Kropotkin joined anarchists from all around Switzerland for a march in Bern. Kropotkin is largely remembered as a peaceable advocate of science and mutual aid, but he and his friends brought flagpoles, brass knuckles, and other weapons to defend themselves. After a lengthy street confrontation, they managed to rescue their red flag from police who tried to seize it, and proceeded to a 2000-strong meeting at which they recited speeches, sang revolutionary songs, and read out telegrams of encouragement from France and Spain.
