The Morosco Theatre was a Broadway theatre located at 217 West 45th Street in the heart of the theater district in midtown-Manhattan, New York, United States.

It was designed by architect Herbert J. Krapp for the Shuberts, who constructed it for Oliver Morosco in gratitude for his helping them break the monopoly of the Theatrical Syndicate. It had approximately 955 seats. It opened on February 5, 1917 with the musical Canary Cottage, with a book by Morosco and a score by Earl Carroll.

The Shuberts lost the building in the Depression, and City Playhouses, Inc. bought it at auction in 1943. It was sold in 1968 to Bankers Trust Company and, after protests failed, razed in 1982, along with the Helen Hayes, the Bijou, and remnants of the Astor and the Gaiety Theatre; it was replaced by the Marriott Marquis hotel and Marquis Theatre.

Bob Martin's musical comedy The Drowsy Chaperone makes mention of the Morosco Theatre. The title is a reference to a fictional show which, according to the narrative, opened at the Morosco in 1928. The narrator goes on to say that the Morosco was demolished in 1982, and a hotel was built in its place. That hotel, of course, is the Marriott Marquis, which houses the Marquis Theatre, where The Drowsy Chaperone opened in 2006.

Gaius Julius Caesar (Classical Latin: [ˈɡaː.i.ʊs ˈjuː.lɪ.ʊs ˈkaj.sar], July 100 BC – 15 March 44 BC) was a Roman general and statesman and a distinguished writer of Latin prose. He played a critical role in the gradual transformation of the Roman Republic into the Roman Empire.

In 60 BC, Caesar, Crassus and Pompey formed a political alliance that was to dominate Roman politics for several years. Their attempts to amass power through populist tactics were opposed by the conservative elite within the Roman Senate^{[citation needed]}, among them Cato the Younger with the frequent support of Cicero. Caesar's conquest of Gaul, completed by 51 BC, extended Rome's territory to the English Channel and the Rhine. Caesar became the first Roman general to cross both when he built a bridge across the Rhine and conducted the first invasion of Britain.

These achievements granted him unmatched military power and threatened to eclipse Pompey's standing. The balance of power was further upset by the death of Crassus in 53 BC. Political realignments in Rome finally led to a standoff between Caesar and Pompey, the latter having taken up the cause of the Senate. Ordered by the Senate to stand trial in Rome for various charges, Caesar marched on Rome with one legion—legio XIII—from Gaul to Italy, crossing the Rubicon in 49 BC. This sparked a civil war from which he emerged as the unrivaled leader of the Roman world.
