avant 1508, le plafond voûté de la chapelle Sixtine était peint en bleu et couvert d'étoiles dorées. Les murs étaient ornés de fresques réalisées par différents artistes, comme Pietro Perugino, qui y a peint le Christ livrant les clés de Saint-Pierre en 1482.
Michel-Ange a commencé à travailler sur les fresques du pape Jules II en 1508, remplaçant un plafond bleu parsemé d'étoiles. depuis sa création, le pape avait demandé à Michel-Ange de peindre le plafond avec un ornement géométrique et de placer les douze apôtres en écoinçons autour de la décoration.

Haymarket Square Riot is a rebellion and an outbreak of violence in Chicago on May 4, 1886. Due to the ever-expanding demands for eight-hour working hours, demonstrations were held on the Haymarket market, organized by a group of anarchists. In a controversial judgment, eight men were sentenced, seven were sentenced to death and one to 15 years in prison. This riot brought the greatest damage to the workers' movement in the United States, The Knight of Labor at that time was the biggest and most successful union organization blamed for the incident. Although the public immediately after the incident was on the side of the police and against the workers 'demands, the struggle of the workers' organizations and trade unions continued for the purpose of eight-hour working hours. Thus, the Socialist International decided to hold demonstrations all over the world on May 1, 1890, as a reminder of the dead and condemned anarchists on May 4, 1896, and to continue the struggle to meet the demands of workers.
