agermanarse

A historical verb tied specifically to the Germanías, the 1519–1523 revolt of Valencian and Mallorcan guild artisans and peasants against the nobility, initially armed with royal permission during a plague outbreak. To agermanarse meant to join that armed brotherhood (germanía) movement; outside this specific historical episode, the verb has essentially no modern use.

• Los artesanos de Valencia se agermanaron en 1519. — Valencia's artisans banded together in the Germanías revolt in 1519.
• El movimiento agermanado se extendió por el Reino de Aragón. — The Germanías movement spread through the Kingdom of Aragon.
• Historiadores estudian por qué tantos gremios se agermanaron. — Historians study why so many guilds joined the Germanías.

Expecting agermanarse to have any everyday meaning — it's essentially a one-context historical term for a specific 16th-century Spanish revolt, not a general verb a learner will need elsewhere.

• politics Germanías — Historical name for the 1519–1523 revolt of Valencian and Mallorcan guild artisans and peasants against the nobility, initially authorized to arm themselves against plague-era disorder and pirate threats before turning into an anti-aristocratic uprising led by figures like Joan Llorenç and Vicente Peris.
