There was a love story in 14th century Portugal like no other. It beats any Shakespearean tragedy, and every child in Portugal knows it by heart. It all began in about 1340 when Portugal and Spain were often in discord, and there were frequent tensions of potential war. And as we all know, political disputes in the past were quite often solved with marriages within the aristocracy.King Pedro at the knees of the dead Queen Ines.At the time, Afonso IV, the King of Portugal, saw a great interest in entering into an alliance with Juan Manuel, the Prince of Villena, a feudal state in the kingdom of Castile located in southern Spain.According to England and Iberia in the Middle Ages, 12th–15th Century a marriage was negotiated between Constanza Manuel of Villena and Dom Pedro, the future King of Portugal.
