"John I (Portuguese: João [ʒuˈɐ̃w̃]; 11 April 1357 – 14 August 1433), also called John of Aviz, was King of Portugal from 1385 until his death in 1433. He is recognized chiefly for his role in Portugal´s victory in a succession war with Castile, preserving his country´s independence and establishing the Aviz (or Joanine) dynasty on the Portuguese throne. His long reign of 48 years, the most extensive of all Portuguese monarchs, saw the beginning of Portugal´s overseas expansion. John´s well-remembered reign in his country earned him the epithet of Fond Memory (de Boa Memória); he was also referred to as "the Good" (o Bom), sometimes "the Great" (o Grande), and more rarely, especially in Spain, as "the Bastard" (Bastardo)." - (en.wikipedia.org 05.06.2020)
