The 1970 NFL–AFL merger was a landmark agreement that combined the National Football League (NFL) and the American Football League (AFL) into a single, unified National Football League. Effective with the 1970 season, the league adopted a unified structure that split teams into the American Football Conference (AFC) and National Football Conference (NFC), setting the foundation for modern league organization.

The merger also established the mechanism for scheduling, championships, and the divisional alignment used at the start of the unified NFL era. While both leagues had long competed for talent and audiences, the 1970 changes formalized cooperation under one league umbrella, including the continuation of the championship pathway culminating in the Super Bowl.

Background and merger impetus

Competition between the NFL and AFL shaped the professional football landscape in the 1960s, influencing player negotiations, television negotiations, and attendance. The AFL, founded in 1960, built a reputation for offensive innovation and quickly became a serious competitor to established NFL franchises. By the late 1960s, both leagues faced escalating costs associated with bidding wars for players, while also recognizing the business benefits of consolidating operations.

The merger followed earlier steps toward cooperation, including increasing coordination on matters such as scheduling and player movement. The combined impact of competition and financial pressure led to the final agreement that created a unified NFL structure beginning with the 1970 season. The resulting arrangement linked the league’s championship and postseason framework more directly to the teams’ conference placement.

The agreement and creation of a single league

The 1970 merger produced a single league that retained the “National Football League” name while integrating AFL franchises into the NFL’s operational framework. Under the unified arrangement, teams were organized into two conferences: the AFC and NFC, a change that streamlined what had previously been parallel league systems.

The new configuration preserved the established identity of the postseason championship structure that culminated in the Super Bowl, which had already been played between NFL and AFL champions. The unified league ensured that, starting in 1970, teams competed within their respective conferences to reach the conference championship contests and, ultimately, the Super Bowl.

AFC and NFC divisional alignment in 1970

A core feature of the merger was divisional realignment to place former AFL and NFL teams into comparable structural groupings. The unified NFL created three divisions within each conference: East, Central, and West. This alignment was designed to reduce travel friction, balance team strength based on earlier performance, and establish a coherent schedule for the new league format.

In the AFC, the former AFL teams and select former NFL teams were grouped to form competitive divisions. The divisional setup included the AFC East, AFC Central, and AFC West. In the NFC, teams were organized into NFC East, NFC Central, and NFC West.

Because the merger unified the league while preserving historical franchises, the divisional alignment became a practical bridge between two distinct league identities. The conference model also influenced how fans and media interpreted team rivalries and standings from the first unified season onward.

Regular season, scheduling, and the postseason pathway

With the merger in effect for the 1970 season, the unified NFL schedule and standings were reorganized around the AFC and NFC. Regular-season results determined division and conference standings, which in turn shaped qualification for postseason play. This structure helped standardize league operations across teams that previously belonged to different organizations.

The postseason system emphasized conference performance, with the league’s championship path leading to the Super Bowl. By maintaining an established culminatory event, the unified NFL could integrate AFL franchises while continuing the brand recognition that had developed around the interleague championship contests in prior years. The postseason and conference framework also helped define the league’s competitive narrative for the 1970s, reinforcing the importance of divisional play and conference matchups.

Legacy and long-term impact

The 1970 merger created a lasting organizational template for professional football in the United States. The AFC–NFC conference structure became central to how the league scheduled games, marketed teams, and developed postseason competition. It also provided a platform for later realignments and expansion cycles that continued to evolve the modern NFL.

The unified NFL era strengthened the league’s overall market position by consolidating two major competitors into one national sports organization. Over time, the conference system and divisional alignment established in 1970 influenced the way rivalries formed and how teams planned roster building in an integrated league environment. Subsequent changes, including later reorganizations of divisions, were built on the foundational merger framework created in 1970.
