Workers' Solidarity Day was celebrated in Lviv from 1890. Annual demonstrations became an element of public policy in the city. The Ukrainians, Poles and Jews of Lviv held them together or separately, national issues ultimately prevailing over social ones.
The economic crisis, inflation, and unemployment caused strikes by builders, the largest group of workers in Lviv, for several years. In 1902, it came to bloody riots with barricades on the streets.
