This biographical history tells the story of 31 Gothic monarchs who fought in the crusades, enforced their feudal rights throughout the kingdom, sponsored the growth of representative government through a parliament, and ultimately created a military power that would dominate European affairs. In the process, the narrative recaptures the dramatic and chaotic span of the years between 1000 and 1400, when the great European monarchies were still in their formative stages.

The book discusses the lives of English and Scottish kings in the context of their eras, discussing their achievements and failures, their relations with the Church and foreign powers, and their overall influence on the suppression of the nobility and the development of the monarchy as the primary governing institution of both Scotland and England.
