King Karl XIII OfSweden

As he was childless, he first adopted Prince Christian Augustus of Augustenburg and, after the sudden death of this heir, the French marshal, Jean Bernadotte, who accepted the election as crown prince and became a Protestant to secure the succession to the throne for himself and his descendants. Even during the lifetime of his adopted father he was the real ruler. As the representative of the interests of his country he came into collision with his former protector Napoleon, joined the allied powers in 1812, and sent 30,000 men to the Army of the North. After the battle of Leipzig he led his troops (of whom he had taken great care) against the Danes. Denmark was made to sign yielded Norway to Sweden. The unwilling Norwegians only consented under pressure of circumstances, and their differences with Sweden were never fully settled.
