Hitler's Rise to Power: Consolidation of Nazi Power

On May 2, 1933, Adolf Hitler banned trade unions. First, the KPD (German Communist Party) was banned on March 6 (soon after the first concentration camp at Dachau was built to hold communist political prisoners on March 22). Trade unions were banned on May 2. The SPD and any new political parties were banned on July 14. In other words, Germany became a one party state under the policy of Gleichschaltung, coordinated Nazi fixation.
