This comprehensive analysis examines the Primeira Liga’s evolution, highlighting its history, structure, and lasting impact, tracing its journey from its origins to its current status among Europe’s elite leagues.
Early Years of Portuguese Football (1922–1938)

Pre-League Era
Football was introduced to Portugal in the late 19th century, influenced by British expatriates and Portuguese students returning from England. In its early days, matches were informal, with clubs primarily competing in regional tournaments rather than a unified national league.
The fist attempt at a nationwide football competition came in 1922, The Campeonato de Portugal, was established. This knockout-style competition, similar to the modern Taça de Portugal, determined the national champion. However, as it lacked a league-based structure, it did not provide a season-long ranking of teams.
The Birth of a National Football League

By the early 1930s, Portuguese football had gained significant popularity, making the need for a structured national league more evident. Up until then, football remained largely regionalized, with the Campeonato de Portugal serving as the country’s main tournament. However, as a knockout competition, it did not function as a true league system, prompting discussions about the creation of a more comprehensive format.
In 1934, the Portuguese Football Federation (FPF) introduced the Campeonato da Liga da Primeira Divisão, an experimental league designed to determine Portugal’s best football team using a round-robin format, allowing teams to compete across a full season rather than in an elimination-style tournament. Unlike the Campeonato de Portugal, which operated as a cup competition, the league provided a more consistent assessment of each club’s performance.
The league’s first edition featured eight teams, bringing together some of Portugal’s most prominent clubs. FC Porto won the inaugural championship in the 1934-35 season, making the beginning of a new era in Portuguese football. However, despite this success, the Campeonato de Portugal remained the official tournament for determining the national champion, maintaining its prestige within the Portuguese football.
However, in 1938, the growing influence and structure of the league led to a landmark decision. The Campeonato da Liga da Primeira Divisão was officially renamed as the Campeonato Nacional da Primeira Divisão, establishing it as Portugal’s top football division. Consequently, the Campeonato de Portugal was relegated to a secondary role and later transformed into the modern-day Taça de Portugal (Portuguese Cup).
This transformation solidified the Campeonato Nacional da Primeira Divisão as the primary competition for determining Portugal’s best football club, laying the groundwork for the modern Primeira Liga. Over the decades, the league flourished, attracting world-class talent and strengthening Portugal’s status as a formidable presence in European football.
Expansion and “Big Three” Dominance (1940s-1970s)
League Expansion and Nationwide Growth
as football continued to grow in popularity, the Primera Liga expanded multiple times to include more clubs:
- 1939: League size increased to 10 teams
- 1941: Further expansion to 12 times
- 1946: Grew to 14 teams
These changes allowed clubs from different regions to participate, strengthening national interest and competitiveness in Portuguese football.
The Emergence of the “Big Three”
Between the 1940s and 1970s, three clubs rose to dominance, shaping the landscape of Portuguese football for decades:
- SL Benfica
- FC Porto
- Sporting CP
Collectively known as the “Big Three,” these clubs won the vast majority of league titles and established their dominance.
- SL Benfica emerged as the most successful club of the era, securing multiple championships in the 1950s and 1960s, largely thanks to the incredible performances of legendary striker Eusébio.
- Sporting CP enjoyed significant success in the 1940s and 1950s, led by the prolific goal scorer Fernando Peyroteo.
- FC Porto would later rise as a powerhouse from the 1980s onward, mounting a serious challenge to Benfica’s supremacy.
Benfica’s Golden Era in Europe
The 1960s marked a historic period for SL Benfica, as the club cemented its status among Europe’s elite. Under the guidance of legendary manager Béla Guttmann, Benfica achieved back-to-back victories in the European Cup titles (now the UEFA Champions League) in 1961 and 1962,defeating Barcelona and Real Madrid, respectively.
Benfica’s triumphs on the European stage not only brought prestige to the club but also enhanced Portuguese football’s global reputation, with stars like Eusébio gaining global recognition for their talent and contributions to the sport.

During this period, Porto consistently won domestic league titles and built a reputation for their disciplined tactical approach, making them a formidable contender in European competitions.
Boavista’s Historic League Victory
During the 1999–2000 season, Boavista FC made history by becoming just the second club outside the “Big Three” to win the Primeira Liga title. Prior to them, only C.F. Os Belenenses, in 1945–46, had managed to break the long-standing dominance of Benfica, Porto, and Sporting CP in Portuguese football.
