Hitler re-militarized Germany by reestablishing the German military, the Wehrmacht, in 1935, which was prohibited under the treaty. Additionally, he conducted a series of military campaigns, such as the annexation of Austria in 1938 and the invasion of Czechoslovakia in 1939, which violated the territorial provisions of the treaty. Furthermore, Hitler ignored the restrictions on Germany's arms production and stockpiled weapons and munitions, including developing and testing new weapons. All these actions directly contradicted the terms of the Treaty of Versailles, which aimed to disarm and weaken Germany after World War-1.
