ABSTRACT The article focuses on analysing Dueñas, a territory located in the central Duero valley, between the tenth and twelfth centuries. A relatively extensive, although not trouble-free, documentary record allows a reconstruction of the evolution of this area in certain aspects: the presence of a castle that could be a landmark of royal power since the tenth century, and the territory’s geographic and social dimension, with special emphasis on communal spaces. The idea of a previous territory is suggested where royal control took over and created a series of political dynamics that led to the royal lordship or realengo. However, the central role of communal usage in the definition of territory and the idea of the realengo’s origin in this region are reconsidered.

杜罗盆地中部的领土和王国：杜尼亚斯（十至十二世纪）

摘要本文重点分析十世纪至十二世纪之间位于杜罗河谷中部的杜尼亚斯。相对广泛但并非毫无问题的文献记录可以在某些方面重建该地区的发展：城堡的存在可能是十世纪以来皇家权力的地标，而且该领土的地理和社会规模，特别强调公共空间。提出了先前领土的想法，由王室控制权接管并产生了一系列政治动力，从而导致了王室的领地或重新实现。但是，重新考虑了社区用法在领土定义中的核心作用以及realengo起源于该地区的想法。
