Little England beyond Wales is a name that has been applied to an area of southern Pembrokeshire and southwestern Carmarthenshire in Wales, which has been English in language and culture for many centuries despite its remoteness from England. Its origins may lie in the Irish, Norse, Norman, Flemish and Saxon settlement that took place in this area more than in other areas of South West Wales. Its northern boundary is known as the Landsker Line.
A number of writers and scholars, ancient and modern, have discussed how and when this difference came about, and why it should persist, with no clear explanation coming to the fore.
