ABSTRACT
The relationship of criatio, established since infancy, is marked by juridical informality but constitutes of a strict and long-lasting bond. Within the context of great political instability and partisanship in Portugal during the 1380s, these relationships would have been useful instruments to the emerging leadership in the fight against its opponents. Thus, during the period from 1383 to 1385, the rise of the Master of Avis as a political alternative depended, first and foremost, on the support of the young people who were bound to him or his allies in the composition of his political society. Exploring this theme is possible thanks to the tools of the prosopography- which can be applied to documentary materials such as the Royal Chancellery, the Chronicle of Joanine, and other special documentation - as well as the classical and contemporary historiography, which covers the rise of the Avis Dynasty.
