Early life
Louis was born in Saarbrücken as the second child and first son of William Henry of Nassau-Saarbrücken and his wife Princess Sophie of Erbach-Erbach.
Like his father, he was educated at the University of Strasbourg. His Grand Tour led to England (from 1759 to 1766), and the Netherlands, France, and Germany.
Career
After his father's death in 1768, Louis took up the business of government in Nassau-Saarbrücken. He largely continued his father's economic policies, but was increasingly subject to financial constraints, so that he had to mortgage the Lordship of Jugenheim to the principality of Nassau-Usingen from 1769 until 1777. In 1770, he requested Emperor Joseph to appoint a Debt Commission. This commission was dissolved in 1782. Since his financial position was still tight, Louis moved his seat of government from the palace in Saarbrücken to his smaller hunting lodges in the surrounding area, such as Schloss Jägersberg.
Despite his tight financial position, Louis was able to complete some construction projects. In 1769, he constructed the Ludwigberg palace and garden on the Malstatter Bahn. In 1775, he completed the Ludwigskirche by Friedrich Joachim Stengel, which his father had begun.
