James II and VII (14 October 1633 – 16 September 1701) was King of England and Ireland as James II and King of Scotland as James VII, from 6 February 1685 until he was deposed in the Glorious Revolution of 1688. The last Roman Catholic monarch of England, Scotland and Ireland, his reign is now remembered primarily for struggles over religious tolerance. However, it also involved the principles of absolutism and divine right of kings and his deposition ended a century of political and civil strife by confirming the primacy of Parliament over the Crown.

Louis XVIII (Louis Stanislas Xavier; 17 November 1755 – 16 September 1824), known as "the Desired" (le Désiré), was King of France from 1814 to 1824, except for a period in 1815 known as the Hundred Days. He spent twenty-three years in exile, from 1791 to 1814, during the French Revolution and the First French Empire, and again in 1815, during the period of the Hundred Days, upon the return of Napoleon I from Elba.

Maria Callas, Commendatore OMRI (/ˈkæləs/; Greek: Μαρία Κάλλας; December 2, 1923 – September 16, 1977) was an American-born Greek soprano. She was one of the most renowned and influential opera singers of the 20th century. Many critics praised her bel canto technique, wide-ranging voice and dramatic interpretations. Her repertoire ranged from classical opera seria to the bel canto operas of Donizetti, Bellini and Rossini and, further, to the works of Verdi and Puccini; and, in her early career, to the music dramas of Wagner. Her musical and dramatic talents led to her being hailed as La Divina.
