This work presents the development of a theoretical model of land management (with its resources and inhabitants) for Thinite Egypt (the period when the kings coming from the city of This and buried in Umm el-Qaab cemeteries ruled most of Egypt). This volume is divided into three parts: textual analysis of Thinite inscriptions ; the second part is a synthesis of the data achieved with the former analysis, delineating a historical model of Early Egyptian State. The third part includes an appendix containing 28 tables with a further complete analysis of all the inscriptions in a tabular and really easy-consulting format. Finally there are 33 plates with the figures of almost all the inscription used in the volume.
