Società Sportiva Lazio, commonly referred to as Lazio, is an Italian professional sports club based in Rome, most known for its football activity. The society, founded in 1900, plays in the Serie A and have spent most of their history in the top tier of Italian football. Lazio have been Italian champions twice, and have won the Coppa Italia six times, the Supercoppa Italiana four times, and both the UEFA Cup Winners' Cup and UEFA Super Cup on one occasion.
The club had their first major success in 1958, winning the domestic cup. In 1974, they won their first Serie A title. The 1990s have been the most successful period in Lazio's history, seeing them win the UEFA Cup Winners' Cup and UEFA Super Cup in 1999, the Serie A title in 2000, and reaching their first UEFA Cup final in 1998. Due to a severe economic crisis in 2002 that forced president Sergio Cragnotti out of the club along with several star players being sold, Lazio's success in the league declined. In spite of the lower funds, the club has won three Coppa Italia titles since then; in 2004, 2009 and 2013.
