Frederick the Great, ruled Prussia from 1740 until his death, leading his nation through multiple wars with Austria and its allies. His daring military tactics expanded and consolidated Prussian lands, while his domestic policies transformed his kingdom into a modern state and formidable European power. Frederick inherited a well-run state from his father, a circumstance that allowed him to fight his major wars. But he worked as hard at internal administration as at military leadership. His ruthless insistence on hard work and honesty resulted in a doubling of the revenues of the state in his reign and a tripling of the available reserve fund, this last in spite of the devastation associated with the Seven Years War. Frederick was a strict mercantilist, fostering the rather backward domestic industry with high tariffs wherever he could.
