The Kingdom of Vlandia is a kingdom in Mount&Blade II: Bannerlord. It is ruled by King Derthert, and occupies the western forests and coastal plains of the Calradian continent.

The Vlandian kingdom, named after the early warlord Wilund the Bold (Valandion, in Calradic), began as a large number of barbarian tribes, who migrated into former Battanian lands during the waning period of the Calradic Empire. The Empire was at war on all sides, so it offered these new barbarian tribes land grants in exchange for mercenary work. Unfortunately, this gave Vlandian nobility a taste for Empire lands, and they united under King Osrac IronArm to conquer the far west of the Empire and declare themselves an independent nation.

Militarily, the Vlandians are best known for their powerful, wellarmoured heavy cavalry units who charge with couched lances. They also field welltrained crossbowmen, and their troops gain 20% more experience from each battle. They start with slightly more territory than the other factions, but are vulnerable to internal dissent.

Vlandia is the predecessor to the Kingdom of Swadia in Warband. In Warband, Vlandia's old and more expansive land is split between the Rhodoks, who rebelled and split off from Swadia, the Swadians in central Vlandia, and the Nords who were able to take a portion of northern Vlandia. Charas in the south is Sarranid territory in Warband, presumably the predecessor to the Sarranid capital of Shariz.
