The document outlines various Bulgarian migration movements driven by factors such as war, poverty, political reasons, and religious intolerance throughout history, with significant emigrations occurring after World War I, World War II, and during democratic changes in 1990. It details the destinations and estimated numbers of migrants during these periods, including over a million people who emigrated due to poverty in 1990 and 150,000 due to the second world war.
