Which football clubs have won the league title in their centenary year?

“How many clubs worldwide have won the league title in their centenary year and which was the first?” asks Masai Graham.

Quite a few clubs have celebrated the big 100 with a league title, Masai. Alan Gomes gets the ball rolling with an example in Portugal. “Porto’s official date of foundation is September 1893. And Porto won the Portuguese title for the 1992-93 season. There is, however, some controversy about when Porto were founded. The club recognises 1893 as its official foundation year, however, the club’s founder, António Nicolau de Almeida, was persuaded in the late-1890s by his English wife to abandon football, which she apparently deemed “too violent”. The club lay dormant until 1906, when it was “refounded”. But if you want to use 1906 as the starting point instead of 1893, well, Porto won the 2005-06 Portuguese league as well.”

Peter Collins gets symmetrical. “Chelsea won their first league title in 1954-55, 50 years after being founded, and their second in 2004-05, 100 years after being founded.” From there, Richard Wilson takes us to the former Yugoslavia. “There are a few centenary champions but some of their claims are more disputed than others,” he writes. “Dinamo Zagreb were formed in 1911 as HSK Gradanski and won a league and cup double in 2010-11. However, given Gradanski were disbanded after World War Two, owing to the perception of the club by the Partizans as collaborationist (as so many clubs in Yugoslavia were), there’s a fair argument to make that the club were only formed out of their ashes in 1945 and, as such, we’ll need to wait to see if they pull a centenary title off. The club would definitely claim heritage back to Gradanski’s start.
