Professional Football Club Ludogorets 1945, commonly known as Ludogorets Razgrad or simply Ludogorets, is a Bulgarian professional association football club founded in 1945 based in Razgrad which currently competes in the First Professional Football League, the top-tier of the Bulgarian football league system. In their inaugural 2011–12 season in A Group after promotion, Ludogorets won the treble by capturing the league championship, the Bulgarian Cup and the Bulgarian Supercup. Subsequently, the club made a significant continental impact in the 2013–14 UEFA Europa League when they reached the Round of 16 in only their second European run. To date they have reached the knockout stages of the Europa League four times, more than any other club in Bulgaria. Ludogorets are also only the second Bulgarian team after Levski Sofia to enter the group stage of the UEFA Champions League, a feat which they achieved in the following 2014–15 season.
