Maurice of Nassau (1567–1625) was stadtholder of the United Provinces of the Netherlands from 1585 until his death. He succeeded his father William the Silent in that role, although the position was not hereditary. On the death of his half-brother Philip William in 1618, he also became the sovereign Prince of Orange. Maurice was responsible for organising the Dutch rebellion against Spain into a coherent, successful revolt. He won great fame as a military strategist and his training methods affected the entire conduct of warfare.
