The reign of Alfonso VII occupied more than a quarter century during which the political landscape of medieval Spain was altered significantly. It was marked by the enhancement of royal administration, an increased papal intervention in the affairs of the peninsular church, and the development of the church's territorial structure. With the publication of The Kingdom of Leon-Castilla Under King Alfonso VII, 1126-1157, Bernard Reilly completes a detailed, three-part history of the largest of the Christian states of the Iberian peninsula from the mid-eleventh through the mid-twelfth century. Like his earlier books on the reigns of Queen Urraca and King Alfonso VI, this will no doubt be an essential resource for all students of European and Spanish history and to anyone investigating the antecedents of Castile's eventual preeminence in Iberian affairs.
In this introduction to commutative algebra, the author choses a route that leads the reader through the essential ideas, without getting embroiled in technicalities. He takes the reader quickly to the fundamentals of complex projective geometry, requiring only a basic knowledge of linear and multilinear algebra and some elementary group theory. The author divides the book into three parts. In the first, he develops the general theory of noetherian rings and modules. He includes a certain amount of homological algebra, and he emphasizes rings and modules of fractions as preparation for working with sheaves. In the second part, he discusses polynomial rings in several variables with coefficie...
Tamar Herzog asks how territorial borders were established in the early modern period and challenges the standard view that national boundaries are settled by military conflicts and treaties. Claims and control on both sides of the Atlantic were subject to negotiation, as neighbors and outsiders carved out and defended new frontiers of possession.
Con el presente trabajo, el autor nos ofrece un corpus genealógico que contiene a todas las grandes familias de la Edad Media peninsular, desde el siglo VIII hasta finales del siglo XV. La obra se divide en tres partes: Galicia, León y Castilla. El interés del tema es evidente, cuando constatamos la extraordinaria importancia que el estudio de la genealogía implica para el mejor conocimiento del mundo medieval. Nos encontramos con una sociedad de carácter estamental, regida por diversos linajes, todos ellos interconectados entre sí. Todo el entramado social que late por debajo de ellos está constituido por un conjunto de familias de segundo rango, también interconectadas entre sí, y...
