On 24 May 1915, a group of students in Sofia founded Sport Club Levski. Now known as Levski Sofia, they have won a Bulgarian-record 55 major domestic trophies, including 26 league titles and 26 Bulgarian Cups.
Named after 19th Century Bulgarian revolutionary Vasil Levski, the club got off to an inauspicious start, losing their first official match 0-2 to FC 13 Sofia. But they won their first regional title in 1923, then followed that with two more in 1924 and 1925.
They won their first league title in 1933 and enjoyed tremendous post-war success, winning five more titles between 1946 and 1953. Since them they have won multiple league titles in every decade, up to their most recent one in 2009. Their tally of 26 league titles is second only to local rivals CSKA Sofia, who have 31.
Levski have also starred in European competitions, advancing to the Cup Winners' Cup quarterfinals three times (1970, 1977, 1987) and the UEFA Cup quarterfinals two times (1976, 2006).
