Rodrigo de Bastidas sailed westward from Venezuela in 1501 in search of gold, and became the first European to explore the isthmus of Panama. A year later, Christopher Columbus visited the isthmus, and established a short-lived settlement in the Darien. Vasco Núñez de Balboa's tortuous trek from the Atlantic to the Pacific in 1513 demonstrated that the isthmus was indeed the path between the seas, and Panama quickly became the crossroads and marketplace of Spain's empire in the New World. King Ferdinand II assigned Pedro Arias Dávila as Royal Governor. He arrived in June 1514 with a 19 vessels and 1,500 men. In 1519, Dávila founded Panama City. Gold and silver were brought by ship from South America, hauled across the isthmus, and loaded aboard ships for Spain. The route became known as the Camino Real, or Royal Road, although it was more commonly known as Camino de Cruces (Road of Crosses) because of the number of gravesites along the way.
