William VIII, Landgrave of Hesse-Kassel
# William VIII, Landgrave of Hesse-Kassel

William VIII (10 March 1682 – 1 February 1760) ruled the German Landgraviate Hesse-Kassel from 1730 until his death, first as regent (1730–1751) and then as landgrave (1751–1760).

## Life

Born in Kassel, he was the seventh son of Charles I, Landgrave of Hesse-Kassel and Maria Amalia of Courland. After his elder brother Frederick became King of Sweden in 1720 and his father died in 1730, he became de facto ruler of Hesse-Kassel. He officially became landgrave after his brother's death on 25 March 1751.

Five years later, the Seven Years' War began and William joined with the Prussian and British forces. Hesse-Kassel became an important battlefield and was occupied by France on several occasions. He had a deep, personal friendship with Frederick the Great, King of Prussia, and Holy Roman Emperor Charles VII.

His second son and successor, Frederick, became a Catholic, which led to restrictions on Catholicism in the Calvinist landgraviate and the transfer of the Principality of Hanau to his Protestant grandson William.

During his reign, William started building Schloss Wilhelmsthal in Calden and collected paintings, including works by Rembrandt.
