Do you capitalise "North" and "South" of England? [duplicate]
North as an adjective (and other cardinal points) is never capitalized, except when part of a construct that is capitalized in itself, such as a country name (North Korea, South Africa).
As a noun, it is capitalized when used in the game of bridge (North and South play together) and, more commonly, when designating a known part of a country (Virginia joined the North) or of the world (the mysterious East, the history of music in the West).
