Fascinating but also kind of creepy.

I’m on Day 189 of Spanish. RIP duo.

The origins of International Labor Day are found in Chicago, where on May 1, 1886, workers called for a strike for an eight-hour workday.

On May 4, violence broke out in Haymarket Square when a bomb was thrown at police officers. The resulting gunfire resulted in several deaths, including six officers and a number of civilians.

This turning point stimulated trade unions and socialist federations across Europe to declare May 1 an international day of workers" solidarity, formally approved in 1889 at the Paris meeting of the Second International.
