Navarre lost its fueros or home rule following Baldomero Espartero's 1841 coup d'état and subsequent passing of the 1841 Ley de Modificación de Fueros. An agreement was then reached with high-ranking officials of the then newly established Provincial Council (not the sovereign Chartered Council) confirming the new law in Navarre in exchange for keeping certain prerogatives. It was later called the "Compromise Act" or Ley Paccionada. Biscay, Álava, and Gipuzkoa formally refused to accept the 1841 law, hanging instead onto their traditional home rule and the 1839 law, the legal arrangement bringing to a close the First Carlist War.
