The Company would in turn export iron commodities to Venezuela. The Guipuzcoana Company became the first shares based company in Spain, participated by Basque shareholders and the king of Spain. Since 1743, the Company got permission to charter vessels under the French flag, which could trade directly with Venezuela. The main beneficiaries of that decision were no doubt the coast of the Basque province of Labourd, and Bayonne. It began operating in 1730—four ships departed from San Sebastián (Donostia) taking on board a crew of 561 and 40-50 cannons. The vessels were hailed with frontal hostility by the Venezuelan Creoles, a refusal to sell cocoa to the Company, and an uprising against the newcomers and the local Spanish garrison, until control was re-established. The Basques started to settle down in Venezuelan territory on wealthy "haciendas" that boosted plantations and agricultural production. However, the move was resented by other established Creoles based on the fact that it brought down prices to be sold to the Company. The Basques established settlements, built dock facilities, and fortifications. The term "un gran cacao" became a nickname for a member of the new powerful class (and to this day the term is used jocularly in Venezuela for a VIP). It did not help smaller farmers who continued to participate in illegal trading. The Company was instrumental in the development of large-scale cocoa production along the valleys of the coast and encouraged the production of such crops as tobacco, indigo, cotton and coffee. In addition, the company promoted the exploration and settlement of frontier areas, most famously under the border expedition of 1750-1761 headed by a company agent, José de Iturriaga y Aguirre, which resulted in new settlements in the Guayana region. The Company's control of the major ports of La Guaira and Puerto Cabello meant that it effectively monopolized the legal trade of the other Venezuelan provinces. In addition, the Company's strict control of much needed manufactured imports naturally created a lot of resentment in a region which depended on these. Several rebellions took place against the Company and the Basques in which ethnic confrontation came to a head in 1749—a variety of Creole population supported by the Dutch and English vs the powerful Basques supported by the Spanish Crown. The rebellion was led by Juan Francisco de León, a Canary Islander just replaced as Corporal of War (1749), but the Spanish Crown could not shrink from protecting its own interests by supporting the Company, and quelling the uprising that very year.
