The way the season works is quite unique. Instead of one long season, it is split into two short tournaments. The first tournament is called the Apertura, which runs from July to December. The second tournament is called the Clausura, which runs from January to May. This schedule follows the FIFA world football calendar. To find a champion, the league uses a final knockout phase. This special phase is called the liguilla.
To reach the liguilla, teams must perform well in the regular season. The top 10 clubs qualify for this final stage. The top 6 clubs go straight to the quarterfinals. The next 4 clubs must play in a play-in round first. This round decides the last two spots in the quarterfinals. Each tie in the liguilla is played over two matches. The winner is decided by the total score from both games. The champions are then awarded the Liga MX trophy. 
This league has a very long and interesting history. Before 1943, football in Mexico was mostly played by amateur clubs. These clubs played in small regional areas around Mexico City. The first true professional national league began in 1943 as Liga Mayor. It had ten founding clubs, including América and Atlas. The very first champion in the professional era was Asturias. Since then, there have been 113 editions of the league. 
Many famous clubs have built great legacies in Liga MX. América is the most successful club with sixteen titles. Guadalajara and Toluca are also very strong, with twelve titles each. Other successful teams include Cruz Azul with nine titles. Tigres UANL and León have each won eight titles. In total, twenty-four different clubs have won the league at least once. The league is very important for football fans in the United States too. It ranks second in television viewership in the U.S., behind only the English Premier League.

The league operates through a specific tournament structure. The season is divided into two short tournaments to follow the FIFA world football calendar. The first is the Apertura, which runs from July to December. The second is the Clausura, which runs from January to May.
To determine a champion, the league uses a final knockout phase called the liguilla.
Once the quarterfinals begin, the format changes slightly. Each tie is played over two legs, meaning each team plays one match at home and one away. The winner is determined by the aggregate score, which is the total number of goals from both matches. 
The history of professional football in Mexico began long before the current league structure. Before 1943, the sport was in an amateur era. During this time, competitions were held in small regional areas. The Liga Mexicana de Football Amateur Association was formed in 1902 near Mexico City. Other regional leagues also existed in Veracruz, Puebla, Jalisco, and the Bajío. In 1943, the Federación Mexicana de Fútbol established the first true national professional league, called Liga Mayor. The inaugural season featured ten founding clubs, such as América, Atlas, and Necaxa. 
Over time, the league has undergone several name and format changes. From 1949 to 2012, it was known as the Primera División de México. In the late 1950s and early 1960s, many small clubs faced economic difficulties. These clubs struggled because they lacked access to international competitions like the Copa Libertadores. To fix this, the league introduced the liguilla format after the 1970 World Cup. This change was designed to regenerate interest and reward clubs that performed well. In 2012, the league rebranded as Liga MX. This era also saw the introduction of VAR technology testing in 2018 to help referees make better decisions.
Success in the league is defined by the number of titles a club wins. América is the most successful club in history with sixteen titles. Guadalajara and Toluca follow with twelve titles each. Cruz Azul has won nine titles, while Tigres UANL and León have won eight each. In total, twenty-four different clubs have won at least one league title. The league's competitive balance is also affected by promotion and relegation rules. Historically, the bottom club was relegated to the lower division. However, since 2020, promotion and relegation have been suspended until the 2026–27 season. This suspension occurred following the folding of the Ascenso MX during the COVID-19 pandemic.
