With the expulsion of the majority of Germans and the partial resettlement of previously German-speaking parts of Czechoslovakia by Czechs, these territories became czechized after World War II.
"In June 1905, the German language paper Bohemia of Prague reported czechization in Saxony, Germany after a great influx of Czech workers had czechified the town of Ostritz.2 According to Saxon officials, the reports were greatly exaggerated.3 They conceded that while Czech speakers in Saxon communities were fewer than popularly supposed, they were nevertheless worth watching."4
