ENGLISH DESCRIPTION Nationalisms manipulate History to justify their vision of the past. There never was a Catalan-Aragonese Crown, and I prove it in this novel about James I The Conqueror.' -Jose Luis Corral No sovereign ruled in Spain as long as he, none won so many battles, none conquered as many kingdoms as James I The Conqueror, King of Aragon, Valencia and Mallorca, Count of Barcelona and Urgel, Lord of Montpellier. This is his prodigious story, his amazing life told as a novel, his gripping legend in the brightest time of the Middle Ages. With the narrative mastery that characterizes him, the professor of Medieval History and novelist Jos Luis Corral unfolds before the reader's eyes a fascinating story of conquests, rivalries, and passions that is essential to understanding the configuration of contemporary Spain and refute, with the rigor of an impeccably documented historical account, the independence myth of the misnamed 'Catalan-Aragonese Crown.'
