Enlightened despots were absolute monarchs influenced by Enlightenment ideals who sought to reform their nations through rational policies. They allowed religious tolerance, freedom of speech and private property rights while fostering education and the arts. Notable enlightened despots included Frederick the Great of Prussia, Catherine the Great of Russia, and Joseph II of Austria who enacted economic and educational reforms. However, they still ruled by absolute authority and refused to establish constitutions, distinguishing them from constitutional monarchs.
