Today we start telling the story of the Independent State of Croatia, or NDH, lead by Ante Pavelić, and his Catholic fascist group, the Ustasha, after Hitler invaded and broke up the Kingdom of Yugoslavia in 1941. They built concentration camps to house and execute Jews, Roma – and, mostly, Orthodox Christians. Their stated policy towards the roughly two million Orthodox Christians in the NDH was to ‘convert a third, expel a third and kill a third’. They were so brutal, they even disgusted the Nazis.
