The Plantagenets [PDF ebook] 
History of a Dynasty

The story of the Plantagenet dynasty is the story of one of the pivotal ages in English history.
Attitudes and outlooks were formed with regard to a vast array of profoundly important issues.
Such fundamental issues as the relationship between church and state, the nature of government/governance, the interaction of social and economic classes, and ultimately the idea of what it means to be English were all shaped to a great degree by the events of the thirteenth and fourteenth centuries.
