In the late 17th century, many English and Scottish politicians viewed standing armies or permanent units as a danger to the liberties of the individual and a threat to society itself. The experience of the Wars of the Three Kingdoms and the use of troops by both the Protectorate and James VII and II to repress political dissent created strong resistance to permanent units owing allegiance to the Crown or State. Regiments were deliberately treated as the personal property of their current Colonel, carried his name which changed when transferred and disbanded as soon as possible.
