the monte della redenzione degli schiavi, often simply known as the monte di redenzione, was maltese institution which was set up to finance the redemption of maltese people enslaved by ottomans or barbary pirates. it was founded in 1607 by grand master alof de wignacourt, and it existed as an independent institution until 1787, when it was merged with the monte di pietà, forming the monte di pietà e redenzione. the new institution continued the role of redeeming slaves until the early 19th century, when it became redundant after slavery was suppressed.
