Burgoignesc colonial empire
Throughout the Age of Discovery and the Age of Sail the coastal Duchies of Marialanus, Martilles, and Burgundie, of the Kingdom of Dericania, developed colonial empires of various sizes through trading companies. This was precipitated by the Expulsion of the Protestants from southern Levantia following their loss in the Great Confessional War. Many of those protestants were processed off-continent through Burgundie who turned them into a massive global exploration and colonizing force, known as Pharisedoms.
There were also some Catholic coloniae (e.g. Veraise and Islevenin) but it was not as common.
For settlements established by the Bergendii corsairs or Burgoignesc crusaders please see those separate pages as they predate the concept of "colony" as it it is meant in this article.
