In 1938, significant global events shaped the course of history. One notable occurrence was the Munich Agreement, where leaders from Germany, Britain, France, and Italy allowed Adolf Hitler to annex the Sudetenland region of Czechoslovakia in an attempt to prevent war. This act of appeasement ultimately failed to maintain peace in Europe. Additionally, 1938 marked the first appearance of the iconic comic book character Superman, which debuted in Action Comics #1. This introduction laid the foundation for the superhero genre in popular culture, influencing countless characters and stories in comics, movies, and television for decades to come.
