In 1939, magazine publisher Martin Goodman founded Timely Comics, the company that would later become Marvel Comics. Timely's first publication, Marvel Comics No. 1, was released in October 1939 and featured characters including the Human Torch and the Sub-Mariner.
The 1940s ushered in the so-called Golden Age of comic books. During this period, Timely Comics introduced various now-iconic superheroes. These included Captain America who, like many heroes of this era, encapsulated a sense of patriotism as World War II raged on.
