Bermudez's government fell. Faced with war breaking out in the Basque Country, the envoy of regent Maria Cristina's government, the Marquis of Miraflores (a middle-of-the-road liberal), contacted London's City bankers to open a line of credit with the Spanish Treasury (thus pay the next installment of external debt due in July 1834 and get new credit), as well as the British Government in order to garner its political endorsement. An agreement with Nathan and James Rothschild and a loan advance of 500,000 pounds to the Marquis of Miraflores paved the way to the establishment of the Quadruple Alliance that sealed British and French protection to the Spanish government, including military operations (April 1834). As written by one historian: The first Carlist war was fought not so much on the basis of the legal claim of Don Carlos, but because a passionate, dedicated section of the Spanish people favored a return to a kind of absolute monarchy that they felt would protect their individual freedoms (fueros), their regional individuality and their religious conservatism. A vivid summary of the war describes it as follows: The Christinos and Carlists thirsted for each other's blood, with all the fierce ardour of civil strife, animated by the memory of years of mutual insult, cruelty, and wrong.

Basque reasons for Carlist uprising The Spanish liberal government wanted to suppress the Basque fueros and to move the customs borders to the Pyrenees. Since the 18th century, a new emergent class had an interest in weakening the powerful Basque nobility and their influence in commerce which extended throughout the world with the help of the Jesuit order. The centralisers in the Spanish government supported some of the great powers against Basque merchants from at least since the time of the abolition of the Jesuit
