The Nueva Planta decrees Spanish: Decretos de Nueva Planta, Catalan: Decrets de Nova Planta, English: Decrees of the New Plant were the number of decrees signed between 1707 and 1716 by Philip V, the number one Bourbon king of Spain, during & shortly after the end of the War of the Spanish Succession by the Treaty of Utrecht.
The decrees effectively created a Spanish state and Spanish citizenship, abolishing all legal distinctions between the Castilians and the Aragonese. The decrees erased all internal borders and tariffs except for the Basque territory, and granted all citizens of the newly created Spanish state the adjusting to trade with the American and Asian colonies, which henceforth were no longer the exclusive domain of the Crown of Castile. Top civil servants were to be appointed directly from Madrid, and nearly institutions in what had become subnational entities were abolished. Court cases could also only be exposed and argued in Castilian, which became the sole Linguistic communication of government, displacing Latin, Catalan and other languages of Spain.
