Support for the Nazi Party was high in Masuria, especially in elections in 1932 and 1933. Nazis used the Masurian dialect for their political rallies during the campaigning. The government of Nazi Germany changed the names of several Masurian towns and villages from their original Slavic or Baltic Prussian names to new German names in 1938. During World War II the Nazis persecuted and killed Polish speakers in Masuria and imprisoned Polish teachers as well as children who learned Polish. The Nazis believed that in future the Masurians as separate non-German entity, would disappear, while those who would cling to their "foreignness" as one Nazi report mentioned, would be deported. Poles and Jews were considered by Nazis to be "untermenschen", subject to slavery and extermination, and Nazi authorities murdered Polish activists in Masuria, those who weren't killed were arrested and sent to concentration camps.
