Maria Theresa ruled for forty years the wide empire of Austria. Maria Theresa's first challenge was Prussia. They tried to occupy Silesia after the death of her father.
After fifteen years of war and frustration, Maria Theresa was reluctant to get involved in conflicts that might prove unsuccessful. After the death of Francis Stephen, Maria Theresa recognized the eldest of her sixteen children, Joseph II, as emperor and coregent. Joseph II's many fundamental differences in beliefs with his mother, caused anxiety and arguments. Periodically, Maria Theresa considered abdication of the throne. However, she never did abdicate.
