France. While Spain was building its New World empire, France was also exploring the Americas. In 1524, Giovanni da Verrazano was commissioned to locate a northwest passage around North America to India. He was followed in 1534 by Jacques Cartier, who explored the St. Lawrence River as far as present-day Montreal. In 1562 Jean Ribault headed an expedition that explored the St. Johns River area in Florida.
