During the "Trienio Liberal" (1820-1823), the progressive liberals decided to resort to the international money lenders to revert the economic meltdown Spain was facing. They turned to Paris, and particularly London, where many liberals (many of them Freemasons) had fled on Ferdinand VII's comeback (1814). In London and Paris, the liberals ruling (shortly) Spain engaged in negotiations with financiers Nathan Rothschild and James Rothschild. They bailed out the Spanish liberal regime, with Great Britain also supporting it on its last stage, not so much on the strength of its liberal tenets but with a vested view to securing the debt engaged in previous years.
