Career

"When John Louis was 28 years old, the Thirty Year's War broke out. He tried in vain to keep Nassau- Hadamar out of the war. His lands suffered from the passage of all kinds of Imperial and Protestant troops, which plundered and requisitioned them into poverty. Highly indebted, John Louis was forced to sell Esterau to Peter Melander Graf von Holzappel in 1643.

John Louis was raised a Calvinist, and was sent in 1629 by his brothers as a diplomat to Vienna to negotiate a truce with Emperor Ferdinand II. Here John Louis converted to Catholicisn under influence of Wilhelm Lamormaini. John Louis was much appreciated by the Emperor for his diplomatic skills. In 1638 he successfully led the peace negotiations in Cologne and Munster. In 1645 he was added to the Imperial delegation under Maximilian von und zu Trauttmansdorff who negotiated the Peace of Westphalia. By 1647 he had replaced Trauttmansdorff as head of the Imperial delegation and it was he who finalized the treaty. For this he was awarded the Order of the Golden Fleece by King Philip IV of Spain."
