Pere Joan Sala (died 1485) was the leader of the radical remensas in the Second War of the Remences, which began with the uprising of Mieres in 1484.
The Second War of the Remences was motivated by attempted legal action against the assets of the peasants who refused to pay the manorial fees.
[1] Later, Joan Sala took the villa of Granollers, from where the revolt spread through Valles, Maresme and the Baix Llobregat.
When the threat to Barcelona became clear, the authorities reacted and defeated them in Les Franqueses del Vallès (Llerona) in March 1485.
This remensa rebellion succeeded in getting the monarchy, headed by Ferdinand II of Aragon son of John II, involved with the cause of the remensas and after much negotiation Ferdinand announced, on April 21, 1486, the Sentencia Arbitral de Guadalupe.
