Historically, for most of North Wales, the region can be referred to as simply ""Gwynedd"", named after one of the last independent Welsh kingdoms, the Kingdom of Gwynedd. This has led to a stronger sense of Welsh identity and home to more Welsh-language speakers, especially in North West Wales, than the rest of Wales. Those from North Wales are sometimes referred to as "Gogs" (from "gogledd" – the Welsh word for "north"); in comparison, those from South Wales are sometimes called "Hwntws" by those from North Wales. The term "North Wales" is rarely applied to all of Wales during the Anglo-Saxon invasion of Britain and the period of the Heptarchy, to distinguish it from "West Wales", known today as Cornwall, although the term "Wales" or the names of the various petty kingdoms of Wales ("Gwynedd, and Powys" in North Wales) are more commonly used to depict the region during this time.
