The Berlin State Opera (German: Deutsche Staatsoper Berlin) is a German opera company based in Berlin. Its permanent home is the Staatsoper Unter den Linden, commonly referred to as Lindenoper, in the central Mitte district, which also hosts the Staatskapelle Berlin orchestra. Originally the Hofoper (court opera) from 1742, it was named Königliches Opernhaus (Royal Opera House) in 1844, and Staatsoper Unter den Linden in 1918. From 1949 to 1990 it housed the state opera of East Germany. Since 2004, the State Opera company belongs to the Berlin Opera Foundation, like the Deutsche Oper Berlin, the Komische Oper Berlin, the Berlin State Ballet, and the Bühnenservice Berlin (Stage and Costume Design).
King Frederick II of Prussia shortly after his accession to the throne commissioned the original building on the site. Construction work began in July 1741 with what was designed by Georg Wenzeslaus von Knobelsdorff to be the first part of a "Forum Fredericianum" on present-day Bebelplatz. Although not entirely completed, the Court Opera (Hofoper) was inaugurated with a performance of Carl Heinrich Graun's Cesare e Cleopatra on December 7, 1742. This event marked the beginning of the successful, 250-year co-operation between the Staatsoper and the Staatskapelle Berlin, the state orchestra, whose roots trace back to the 16th century.
In 1821, the Berlin Opera—hosted at the Schauspielhaus Berlin—gave the premiere of Weber's Der Freischütz. In 1842, Wilhelm Taubert instituted the tradition of regular symphonic concerts. In the same year, Giacomo Meyerbeer succeeded Gaspare Spontini as General Music Director. Felix Mendelssohn also conducted symphonic concerts for a year.
