Oranier - a company with tradition

The noble family of Oranien Nassau dates back to the late 11th century. The counts named themselves after the Castle Nassau an der Lahn, close to Bad Ems. Through marriages and successions, the area expanded, on the one hand, to the region known today as the Netherlands, and, on the other hand, to the French Orange (or in German: Oranien). The noble family has thus held the double name Oranien-Nassau since the 16th century.

The famous Dillenburg scion, Wilhelm I, while educated in the Catholic faith was in fact very tolerant in religious matters. He assisted the Dutch in their fight against the Spanish and was able to free the Netherlands from the dyed-in-the-wool conservative Catholics.

Wilhelm I had 13 children. His son Moritz stayed in the Netherlands. Many generations later, succession was no longer tied to the male offspring, and Wilhelmina, and later Beatrix, could be crowned Queen of the Netherlands.
