International Workers' Day
International Workers' Day, also known as May Day, is celebrated on May 1st each year to honor the contributions and struggles of workers and the labor movement. It commemorates events like the Haymarket Affair of 1886, which highlighted the fight for workers' rights, including the demand for an eight-hour working day. In socialist states such as the Soviet Union and People's Republic of China, International Workers' Day was a major holiday, celebrated in every city and town, marked by parades and demonstrations celebrating the achievements of the labor movement in these countries.
Although many countries around the world celebrate it, reactionary anti-communist countries like the United States don't, preferring to celebrate Labor Day instead. This was done deliberately to prevent American workers from having international solidarity with workers across the world.
