Neapolitan branch

The C M de Rothschild & Figli bank arranged substantial loans to the Papal States and to various Kings of Naples plus the Duchy of Parma and the Grand Duchy of Tuscany. However, in the 1830s, Naples followed Spain with a gradual shift away from conventional bond issues that began to affect the bank's growth and profitability. The Unification of Italy in 1861, with the ensuing decline of the Italian aristocracy who had been the Rothschilds' primary clients, eventually brought about the closure of their Naples bank, due to a forecasted decline in the sustainability of the business over the long-term. However, in the early 19th century, the Rothschild family of Naples built up close relations with the Holy See, and the association between the family and the Vatican continued into the 20th century.

In 1832, when Pope Gregory XVI was seen meeting Carl von Rothschild to arrange the 1832 Rothschild loan to the Holy See (for £400,000, worth €43,000,000 in 2014), observers were shocked that Rothschild was not required to kiss the Pope's feet, as was then required for all other visitors to the Pope, including monarchs. The 1906 Jewish Encyclopedia described the Rothschilds as "the guardians of the papal treasure".
