With the banning of private armies in the late 18th century, the relation of the Scottish clan chiefs to their kinsmen and tenants became increasingly economic rather than military. Overpopulation of the Highlands, the failure of the Kelp industry and then of the potato crop in the 1840s left sheep as the only profitable Highland product. This eventaully led to the forced removal of many thousands of Highland tenants from their ancestral lands. Widely regarded as a betrayal of trust, the clearances brought to an end any remaining romantic-feudal notions of duty and obligation in the face of the forces of market capitalism. Prebble convincingly portrays the nature of the New Realism. (Kirkus UK)
