Answer:

Image result for Maria Theresa, what form of government did Maria Theresa support?
Maria Theresa was a devout Roman Catholic and believed that religious unity was necessary for a peaceful public life. Consequently, she explicitly rejected the idea of religious toleration but never allowed the Church to interfere with what she considered to be prerogatives of a monarch and kept Rome at arm's length.
Though the official ruler was actually her husband, Francis I, she governed the Habsburg monarchy single-handedly. When her husband became the emperor of the Holy Roman Empire in 1945, Maria Theresa acquired the title of empress, as suits the wife of an emperor.
