The Kingdom of Holland was the successor state of the Batavian Republic. It was created by Napoleon Bonaparte in March 1806 in order to strengthen control over the Netherlands by replacing the republican government with a monarchy. Since becoming emperor in 1804, Napoleon sought to extirpate republican tendencies in territories France controlled, and placed his third brother, Louis Bonaparte, on the throne of the puppet kingdom. The name of the leading province, Holland, now designated the whole country. In 1807, East Frisia and Jever were added to the kingdom.
