Polish community seeks to learn more about its Jewish heritage

Poland is marking 70 years since the start of the Warsaw ghetto uprising. It was the first major act of resistance against the occupying Nazis during World War II and went down in history as a heroic act to restore the dignity of a condemned people. Indeed, of the 6 million Jews killed by the Nazis, half of them were Polish. Poland had the largest Jewish population of any country before World War II; it now has only around 20,000.
