What were the fueros that Philip V abolished in parts of Spain?

In the context of Spanish history, fueros were local privileges, exemptions, or municipal franchises granted by the crown, nobles, or bishops to specific communities or regions. These legal codes often confirmed local customs, granted rights to self-government, or provided tax exemptions, effectively creating a decentralized system of "little republics" within the kingdom.12

During the War of the Spanish Succession, Philip V and his Bourbon reformers viewed these fueros as obstacles to effective royal rule and centralized administration. Because regions like Aragon, Valencia, and Catalonia supported the rival Austrian candidate, their local privileges were increasingly seen by the Bourbon monarchy as covers for treason.3

Following the victory at Almansa in 1707, Philip V abolished the fueros of the kingdoms of Valencia and Aragon. Later, after the capture of Barcelona in 1714, he issued the Decree of Nueva Planta (1716), which abolished the fueros of Catalonia and integrated the region into a more unitary Spanish state under direct royal administration.3
