The Scots Gaelic Myth

[Damion]

Perhaps this is the real reason why the Lowlands were more anglicised -gaelic was just a culture foisted upon them by invaders from Ireland so absorbing the later incoming cultures came just as easily?...

The lowlands were easily accessible to development during the Middle Ages and that development was carried out by Europeans and English. Once the principal trade towns were English speaking then trade became an English speaking endeavour and Gaelic was pushed further back.
