Engelbert Dollfuss
In January 1934, Kaltenbrunner was briefly jailed at the Kaisersteinbruch detention camp with other Nazis for conspiracy by the Engelbert Dollfuss government. While there he led a hunger strike which forced the government to release 490 of the party members. In 1935, he was jailed again on suspicion of high treason. This charge was dropped, but he was sentenced to six months imprisonment for conspiracy and he lost his license to practice law.
