The House of Bourbon-Sicily was a royal dynasty that ruled over the Kingdom of Sicily and later the Kingdom of the Two Sicilies from the 18th to the 19th centuries. It originated from the Bourbon family, which had its roots in France. The dynasty played a significant role in the politics of Southern Italy and was known for its efforts to modernize the region. The House of Bourbon-Sicily was established when Charles III of Spain, a Bourbon, became King of Naples and Sicily in 1734. The dynasty faced various challenges, including revolutions and foreign invasions, but it remained influential until the unification of Italy in the 19th century, which led to the dissolution of the kingdom.
