History

Wars, epidemics (such as AIDS), pandemics, and poverty have led to many children becoming orphans. The Second World War (1939-1945), with its massive numbers of deaths and vast population movements, left large numbers of orphans in many countries—with estimates for Europe ranging from 1,000,000 to 13,000,000. Judt (2006) estimates there were 9,000 orphaned children in Czechoslovakia, 60,000 in the Netherlands 300,000 in Poland and 200,000 in Yugoslavia, plus many more in the Soviet Union, Germany, Italy, China and elsewhere.
