Joachim Irgens von Westervick

Joachim Irgens von Westervick (Danish: Joachim Irgens von Westervick; spelled also af Westervig and af Vestervig) (19 May 1611 - 29 August 1675), born as Jochum Jürgens, was a Dano-Norwegian nobleman, a Danish official and an estate owner in Denmark, Norway, and the Netherlands. The Danish variant of his name by birth was Joachim Irgens.

Joachim Jürgens was the son of merchant Heinrich Jürgens and Catharina Fruchtnichts in Itzehoe in Holstein. He married in 1656 Cornelia Bickers, the daughter of the Mayor of Amsterdam, Andries Bicker. Like his brother Johannes Jürgens (Irgens), he studied medicine. However, after having travelled around the world, he became in 1634 the Lord Chamberlain of King Christian IV of Denmark and Norway and later Frederick III of Denmark and Norway.

Joachim Irgens was early involved as an owner of various mines, among others Røros Copperwork.

Due to in the 1650s having provided the King's wars with considerable amounts of deliveries, Joachim Irgens received as payment, on 12 January 1666, all the crown estate in Helgeland, Salten, Lofoten, Vesterålen, Andenes, Senja, and Troms in Norway. It was and is the biggest single sale of land ever to happen in the Nordic countries. This sale represented 50 percent of all property in Northern Norway, and the value was calculated to 100,000 riksdaler, equivalent to 2,700 kilogrammes of gold. Together with the properties, Irgens got the right to all annual rent fees as well as e.g. tithe, the Lap tax and leidang.
