The historical development of English law resulted in the division of the law into three main branches: common law, equity, and criminal law. The common law as administered by the king's court developed into a rigid system of formal actions, with relief by way of money damages as the one remedy in personal actions. This development, together with the growth of highly technical rules of pleading, left many situations in which no adequate relief was available in those courts; and the resulting inflexibility of the system led to the growth of equity, under which the king's prerogative might be exercised to provide justice in such situations.'
