By 1650, Oliver Cromwell had risen from a humble country squire to the effective ruler of England. But the Treasury was empty and he was obliged to resort to the traditional methods of trade and warfare in order to refill the national coffers. With France and Spain at each other's throats, and in return for a generous subsidy payment, he offered each of the bitter rivals an alliance against the other.
