The first International Workers' Day

The 1st of May was first marked as International Workers’ Day in 1890, when the Second International called for demonstrations to commemorate the Haymarket massacre (in which violence at a rally in Chicago in support of an eight-hour working day resulted in the deaths of several workers and police). International Workers’ Day, or May Day, is celebrated around the world and is a public holiday in most countries.

Here are some of the documents from May Day in the archive:
