How did the Nazi annexation of Austria in 1938 affect Anton Webern's career?

The Nazi annexation of Austria in 1938 had a devastating impact on Anton Webern’s career and livelihood. Because the Nazi regime branded the music of the "New Vienna school" as "cultural Bolshevism" and "degenerate art," performances of his works were banned.1

This political upheaval resulted in several severe consequences for the composer:

• Economic Hardship: His economic situation became desperate as he lost almost all of his private pupils. To survive, he was forced to accept menial tasks, such as creating piano arrangements of works by lesser composers.1
• Professional Stagnation: The annexation brought a complete halt to the publication of his music.1
• Isolation: Already suffering from the loss of his friend and colleague Alban Berg in 1935, Webern’s artistic isolation became complete following the 1938 political changes. By the outbreak of World War II, he had fallen into total obscurity.1
