On March 20, the International League of Peoples' Struggle (ILPS) will be launching its six-week long global campaign to commemorate the 150th anniversary of the Paris Commune of March 18 to May 28, 1871. The “Paris Commune at 150” campaign (PC150) will be a global mass commemoration to refresh, revitalize and sustain interest in the Paris Commune: its historical context and impact in the past 150 years, its lessons and continuing validity for the current era.
