After the fall of Napoleon, Napoleon's wife, Maria Louisa, was made Duchess of Parma. As compensation, Charles Louis, the former king of Etruria, was made the Duke of Lucca. When Maria Louisa died in 1847 he was restored to Parma as Charles II. Lucca was incorporated into Tuscany. He was succeeded by his son, Charles III, and grandson, Robert I, in 1854. The people of Parma voted for a union with the kingdom of Sardinia in 1860. After Italian unification the next year, the Bourbon dynasty in Italy was no more.
