The circumstances and methods which enabled the Basques to preserve this independence were, first, the isolation caused by their peculiar language; next, the mountainous and easily-defended nature of the country, its comparative poverty and the possession of a sea-board. Then there were the rights and the safeguards which the fueros themselves gave against encroachments. ”
