Answer:
The Dawes Plan, the Young Plan, the Locarno Pact and the Kellogg-Briand pact prevented Adolph Hitler and the Nazi Party's rise to power.
Step-by-step explanation:
Much of the success of "Golden Years" in Germany can be attributed to establishment of the American aid plans and measures such as The Dawes Plan, the Young Plan, the Locarno Pact and the Kellogg-Briand pact.
It helped Germany recover and improve its economy, as well as helped in improving its foreign relations. However, with the onset of the Great Depression, it led to the end of the "Golden Years" in 1929.
Loans were withdrawn back and stalled by the American banks and Germany as well as many other countries had to face a very hard time because of this. Unemployment and poverty started to rise and there was economic crises once again in Germany.
It was during these times of crisis, Hitler took the advantage and paved a way for his Nazi party and ideologies in the country. It provided Hitler a platform to advocate his ideologies and condemn the policies of the Weimar republic in Germany.
Thus, it can be said that the plans and measures such as The Dawes Plan, the Young Plan, the Locarno Pact and the Kellogg-Briand pact prevented Hitler and the rise of Nazi party in Germany as those plans and measures helped Germany recover from its war reparations and economic downfall.
