6. Maria Theresa Like all members of the House of Habsburg, Maria Theresa was a Roman Catholic, and a devout one as well. She believed that religious unity was necessary for a peaceful public life and explicitly rejected the idea of religious toleration. However, she never allowed the Church to interfere with what she considered to be prerogatives of a monarch and kept Rome at arm's length. She controlled the selection of archbishops, bishops and abbots.
Brother of Marie Antoinette, Archduke Charles Joseph of Austria (1 February 1745 – 18 January 1761) was the second son of the Habsburg ruler Maria Theresa and her husband, Francis I, Holy Roman Emperor.
