Niels Rosenkrantz

Niels Rosenkrantz (9 September 1757 in Øyestad, Norway - 6 January 1824 in Copenhagen) was a Danish-Norwegian statesman, diplomat and prime minister.

He was re-invited to be the ambassador to the Russian court 1802-04 following Paul I's assassination and the ascension of his successor, Alexander I of Russia.

He became a peace agent to Sweden in 1809, negotiating and signing the Treaty of Jönköping, which ended the Dano-Swedish War of 1808–1809.

However, he became a fairly prosperous landowner when his distant relative Prime Minister Frederik Christian Rosenkrantz designated him as his sole heir.

In 1791, he married Princess Varvara Alexandrovna Vyazemskaya (1774-1849), the youngest daughter of Prince Alexander Vyzemsky, Catherine II's Attorney General.
