What were the consequences of World War 1 to Europe and the us?

World War I had profound consequences for both Europe and the United States. In Europe, the war led to significant political upheaval, the collapse of empires (such as the Austro-Hungarian and Ottoman Empires), and the redrawing of national borders, which sowed the seeds for future conflicts. Economically, many countries faced devastation and debt, contributing to the Great Depression. In the U.S., the war bolstered its global power status, catalyzed economic growth, and led to a tumultuous social change, including the Great Migration and shifts in women's roles.
