Which major global event was a catalyst for the implementation of the New Deal?

The Great Depression was a significant global event that served as a catalyst for the implementation of the New Deal. This economic crisis, which began in 1929 and lasted through the 1930s, led to widespread unemployment, severe financial instability, and a dramatic decline in economic activity. In response to this dire situation, President Franklin D. Roosevelt proposed the New Deal, a series of programs and reforms aimed at economic recovery, job creation, and social welfare.

The New Deal included initiatives to stabilize the economy, support agricultural and industrial recovery, and provide assistance to those in need. It fundamentally reshaped the relationship between the government and the economy and introduced a new social safety net for Americans. The scale and urgency of the Great Depression necessitated bold action, making it a pivotal factor in the creation of the New Deal and its various components, including Social Security and labor regulations.

Other options provided, such as World War I, the Cold War, and the Korean War, are historical events that did not directly influence the establishment of the New Deal. While they shaped various geopolitical landscapes, they were not factors that compelled the specific economic and social reforms initiated by Roosevelt in response to the economic collapse of the Great Depression.
