The elder, Charles, had quarrelled with his uncle and guardian, George IV., and had in 1830 been expelled from his dominions.

The obvious faults of his character made it impossible for the other German princes to insist on his being restored, and he had been succeeded by his younger brother William, who ruled till his death in 1884.

Both died unmarried, and with them the Ducal family came to an end.

One Princess of Brunswick had been the wife of George IV., and another, Augusta, was the first wife of Frederick I., King of Wuertemberg, who, after her death, married a daughter of George III.
The King of Wuertemberg was also, by his descent from Frederick Prince of Wales, first cousin once removed of the Queen.

We need only notice, in passing, the distant connection with the royal families of Prussia, the Netherlands, and Denmark.
