Balboa was born in 1475 in Jerez de los Caballeros, a town in the impoverished Extremadura region of Spain. His father was believed to be a nobleman, but the family was not wealthy; like many of his class, Balboa decided to seek his fortune in the New World. Around 1500, he joined a Spanish expedition that explored the coast of present-day Colombia, then returned to the island of Hispaniola (present-day Haiti and the Dominican Republic) and sought to make his living as a farmer. After falling into debt, he fled his creditors by stowing away on an expedition carrying supplies to the colony of San Sebastian, located on the coast of Urabá (now Colombia), in 1510.
