May Day (First of May), international labour day dedicated to manifestations and celebrations by the labour movement, which took its inspiration from the US movement calling for the eight-hour day and was designated as its international holiday by the Second International Socialist congress in Paris in 1889. From 1890 onwards May 1st was celebrated by the Social Democrats in Vienna and other Austrian cities. It was made a national holiday in 1919, when the Austrian Communist Party also joined the movement. The holiday continued to exist during the Corporate State and under National-Socialist rule. In the 1970s numerous other leftist and alternative groups also adopted May 1st as their holiday. The ideology and objectives of the celebration have but little in common with other May Customs.
