An opera in three acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa, based on Victorien Sardou's drama, La Tosca. The work premiered at the Teatro Costanzi in Rome on January 14, 1900.
Set in the period of the Napoleonic wars, Tosca is based on true events which unfolded in Rome during a period of great turmoil. Puccini put his heart and soul into this story of political intrigue and doomed love. The three principal characters, Tosca, a famous singer, Cavaradossi, an artist and her lover, and Baron Scarpia, head of the secret police who is one of the most evil of operatic villains, are all finely drawn in Puccini's sublime score.
