The year 1920 marked a significant period in history, particularly in the aftermath of World War I. It was a time of social change and economic growth in many countries, especially in the United States. The League of Nations was established in an effort to promote peace and prevent future conflicts, although the U.S. did not join. In the cultural realm, the 1920s began to emerge as the "Roaring Twenties," characterized by a shift in social norms. The 19th Amendment was ratified in the U.S., granting women the right to vote, which was a major milestone in the women's suffrage movement.
