What happened between 1920 to 1930?

Between 1920 and 1930, the world experienced significant social, economic, and political changes. In the United States, the Roaring Twenties saw economic prosperity, cultural flourishing, and the rise of Jazz Music, but it also led to excess and speculation that contributed to the Great Depression. Meanwhile, in Europe, many countries were recovering from the impacts of World War I, and political movements, including fascism, began to gain traction. This decade laid the groundwork for major developments leading into the 1930s, including economic turmoil and the rise of totalitarian regimes.
