Louis Crato, Count of Nassau Saarbrucken

Louis Crato, Count of Nassau-Saarbrucken (German: Ludwig Krafft, Graf von Nassau-Saarbrucken; 28 March 1663, Saarbrucken – 14 February 1713 in Saarbrucken) was the son of Count Gustav Adolph of Nassau-Saarbrucken and Clara Eleanor, Countess of Hohenlohe-Neuenstein. He was educated at Neuenstein with his uncle, Count Wolfgang Julius of Hohenlohe-Neuenstein, and later in Tubingen. His father was at the time a prisoner of war in France.

On his father's death in 1677, he inherited the counties of Saarbrucken and Saarwerden. He could not take up the administration of his territories, because they were occupied by the French. It was probably the search for adventure and the lack of opportunities that led him to enter the French service. He reached the rank of lieutenant general there. During his career he was distinguished by bravery, coolness and military acumen. He took part in the siege and capture of Luxembourg in 1684. During the Nine Years' War he served in the Netherlands Company at the Battle of Fleurus (1690) (severely wounded), the siege of Namur, the Battle of Steenkerke (1692), and the Battle of Neerwinden (1693). The French King rewarded this short spell with the Dutch army by seizing his lands. After the Treaty of Ryswick in 1697, his lands were returned to him and he became Regent. During the War of the Spanish Succession he only served in an advisory role.

He was considered a good ruler, as he could keep his country out of further wars. He organized the administration of justice and the state finances. He showed benevolence and reorganized the school system.

His was succeeded in government by his brother Charles Louis.
