Founded in 1900 as Societa Podistica Lazio, a multi-purpose sports club, the Biancocelesti began football full-time in 1906. Winning one wartime Roman title in 1944, the club lifted their first national trophy - a Coppa Italia - in 1958 but were relegated three seasons later.
Several trips up and down the Divisions preceded Lazio’s first Scudetto in 1973-74 when they were led by the legendary Giorgio Chinaglia. But within five years came the club’s darkest hour as Lazio were relegated for financial irregularities and only a play-off prevented the club from slipping into Serie C in 1987.
Sergio Cragnotti took over the club in 1992 and with his financial backing Lazio became a force both in Italy and Europe. Since 1997 the Biancocelesti have won their second Scudetto, a Cup-Winners Cup, an Italian and European Super Cup and two Italian Cups. However, only massive sales and a restructuring of contracts allowed the club to avoid bankruptcy.
Despite being forced to sell several key players before the 2005-06 campaign, Delio Rossi took the Aquilotti to sixth place. However, after a Calciopoli indictment, Lazio started the season without European football and with an 11-point deduction, yet they managed to improve upon their previous campaign by snatching a Champions League preliminary round spot in 2006-07.
