<p> This thesis examines the relationship between Giuseppe Verdi and the Paris Opera and the stage works that Verdi composed or reworked as a result of this business venture. Between 1847 and 1867, Verdi accepted four formal commissions for Paris: Jerusalem (1847), <i>Les v&ecirc;pres siciliennes </i> (1855), <i>Le trouv&egrave;re</i> (1857) and <i> Don Carlos</i> (1867). After a brief introduction discussing Verdi's career before Paris, each commission is discussed in detail from the genesis of the work through its premiere, and the eventual outcome of each opera. This study also evaluates the benefit of this collaboration to Verdi's international career given the requirements and time expended to produce each commission. It explores Verdi's adaptation to cultural differences, his handling of foreign business affairs, and his personal feelings toward French society. Much of the source material is drawn from Verdi's own writings and correspondence, as well as the writings of several Verdi scholars.</p>
