The NFL was formulated on 17th September 1920 in Ohio, United States, with its original name being the American Professional Football Association. The first president was former athlete and football Player Jim Thorpe, who was instrumental in laying the foundations for the NFL.
12 teams participated in the inaugural NFL campaign in 1920 and comprised of five teams from Ohio, four from Illinois, two from Indiana, and one from Michigan. Two of the original franchises have survived to the present day, the first being the Arizona Cardinals, the other being Chicago Bears.
Despite many years of instability and stiff competition from rival organisations, such as the American Football League (AFL). In 1970, the AFL and NFL merged together with a 26-team league, with NFL name being kept. The league has expanded four times since this merger and continues to be a huge part in US culture.
