Otto von Habsburg
Following the occupation and annexation of Austria by Nazi Germany, the country's monarchists (i.e. supporters of Otto von Habsburg as the rightful Emperor-Archduke and the rule of the House of Habsburg), conservatives as well as supporters of Engelbert Dollfuss' Austrofascist regime, were severely persecuted by the Nazis, as they were seen as opponents of the Nazi regime. Thousands of monarchists were executed or sent to concentration camps, and the pretender to the throne, Otto von Habsburg, fled to the United States, being sentenced to death "in absentia" by the Nazis.
