Answer:
A) He annexed a region called the Rhineland.
E) He set about rebuilding his military forces.
F) He invaded the nation of Czechoslovakia.
Step-by-step explanation:
The Treaty of Versailles had prohibited Germany from having any military forces in the Rhineland, a demilitarized zone along the border with France. However, in 1936, Hitler ordered German troops to reoccupy the Rhineland, in violation of the treaty. This move was a major risk, as it could have led to war with France and Britain, but it ultimately proved successful, as neither country took military action against Germany.
The Treaty of Versailles had placed strict limits on the size and capabilities of Germany's military. However, Hitler began secretly building up the German military in the 1930s, in violation of the treaty. This included increasing the size of the army, navy, and air force, developing new weapons and technologies, and training soldiers and officers for future wars.
In 1938, Hitler demanded that the Sudetenland region of Czechoslovakia be given to Germany. When Czechoslovakia refused, Hitler threatened war and managed to secure the Munich Agreement, which allowed Germany to annex the Sudetenland. However, just months later, in 1939, Hitler invaded the rest of Czechoslovakia, breaking the Munich Agreement and effectively violating the Treaty of Versailles once again. This move was a significant step towards World War II, as it demonstrated Hitler's willingness to use military force to expand Germany's territory.
