context: The Norman expansion in Wales is a series of military-political operations of the kings of England and the Anglo-Norman barons in the late 11th – early 13th centuries, aimed at subjugating the territory of Wales. Beginning immediately after the Norman conquest of England in 1066, the Norman expansion in Wales continued with varying intensity over a century and a half. As a result, the Welsh kingdoms of Gwent, Morgannug, and Briceinog were eliminated, most of the territory of Wales was conquered, where the so-called “Welsh Mark” was created, and classic forms of the feudal social system were introduced. The Norman expansion of the late XI-XII centuries created the conditions for the final conquest of Wales by Edward I in the second half of the XIII century.
