Switching from the counts of Geneva's dwelling in the 13th century, to the counts of Savoy's in the 14th century, the city became Savoy's capital in 1434 during the Genevois-Nemours prerogative until 1659. Its role increased in 1536, during the Calvinist Reformation in Geneva, while the bishop took refuge in Annecy. Saint Francis de Sales gave Annecy its advanced Catholic citadel role known as Counter-Reformation. The annexation of Savoy merged the city to France in 1860. Sometimes called "Venice of the Alps", this idyllic and touristic representation comes from the three canals and the Thiou river lying through the old city and whose initial role was to protect the city and to empower its handicrafts. The city experienced an industrial development in the 19th century with silk manufacturing. Some of its industrial legacy remains today with the headquarters of NTN-SNR bearings, Salomon, Entremont and Dassault Aviation.
