1383–1385 Portuguese interregnum
civil war in Portugal
An interregnum and a war of succession began in the Kingdom of Portugal in 1383 when King Ferdinand I died leaving no sons and ended when King John I was crowned in 1385 after his victory during the Battle of Aljubarrota.
The Portuguese interpret the era as their earliest national resistance movement to counter Castilian intervention, and Robert Durand considers it as the "great revealer of national consciousness".
The bourgeoisie and the nobility worked together to establish the Avis dynasty, a branch of the Portuguese House of Burgundy, securely on an independent throne. That contrasted with the lengthy civil wars in France (Hundred Years' War) and England (War of the Roses), which had aristocratic factions fighting powerfully against a centralised monarchy.
In Portugal it is sometimes known simply as the Interregnum (or the First Interregnum, if the 1580 Portuguese succession crisis is counted as a "Second Interregnum"), the 1383–1385 crisis (Crise de 1383–1385) or the Avis Revolution (Revolução de Avis).
Background
In 1383, King Ferdinand I of Portugal was dying. From his marriage to Leonor Telles de Menezes, only Princess Beatrice of Portugal survived. Her marriage was the major political issue of the day since it would determine the future of the kingdom.
Several political factions lobbied for possible husbands, which included English and French princes. Finally, the king settled for his wife's first choice, King John I of Castile.

Why this record matters
The phrase “civil war in Portugal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q2105495. The Library of Congress control number is sh85105257. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1383, 1385 and 1580.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
