Historia General del Derecho Español, Tomo I

The work presents a systematic history of Spanish law from its origins to the contemporary period, combining an external history of legal sources—custom, legislation, and doctrine—with an internal history of institutions’ origins, development, and decline. It outlines the geographic and chronological scope across the Iberian territories, emphasizes methodological guidance for students, and highlights principal sources and further readings. It argues that historical study is indispensable for correct interpretation and application of current law and explains how legal codes rest on earlier norms, advocating a historical method to understand institutional change and to inform legal reform.
