During the 19th century Puerto Plata was the most important port in the country (and even became provisional capital) and hosted the European and North American migration to the Dominican Republic. The majority were Germans traders and tobacco producers, most of them being from Hamburg and Bremen. There were also Englishmen, Dutch, Spaniards (mainly from Catalonia), Puerto Ricans (at least 30,000 between 1880 and 1940), Cubans (at least 5,000 immigrated during the Ten Years' War) and Italians. After the Restoration War there was an inflow of Americans and French. Most immigrants during this period completely assimilated into the local Dominican population. The most prominent migrants’ surnames that went to this city were "Arzeno", "Balaguer", "Batlle", Bonarelli, "Brugal", Capriles, "Demorizi", "Ferrari", "Imbert", "Lithgow", "Lockward", "McKinney", "Paiewonsky", "Prud’homme", "Puig", "Rainiere", "Villanueva, "Vinelli" and "Zeller".
