The asiento was the license issued by the Spanish crown, by which a set of merchants received the monopoly on a trade route or product. They were included in some peace treaties. An example of it was the payment of a fee, granting legal permission to sell a fixed number of enslaved Africans in the Spanish colonies. They were usually sold to foreigners, mainly Portuguese. They were also considered a tangible asset, comparable to tax farming, and a source of profit for the Spanish crown. The original impetus to import enslaved Africans was to relieve the indigenous inhabitants of the colonies from the labor demands of the Spanish colonists. Dutch merchants became involved in the slave trade. In 1713, the British were awarded the right to the asiento in the Treaty of Utrecht, which ended the War of the Spanish Succession. The British government passed its rights to the South Sea Company. The British asiento ended with the 1750 Treaty of Madrid between Great Britain and Spain.
In many cases, intra-nationally, a seat in the form of financing in the case of economies of scale resulted in a chartered company, which was a commercial company whose activities enjoyed the protection of the State by means of a special privilege, which, although it did not always constitute a total monopoly. Its existence dates back to 14th century in Italy, highlighting the British East India Company, the Dutch West India Company or the Casa de la Contratación de Indias in Seville.
The general meaning of asiento (from the Spanish verb sentar, to sit, and this from Latin sedere) in Spanish is "consent" or "settlement, establishment". In a commercial context it means "contract, trading agreement." In the words of Georges Scelle, it was "a term in Spanish public law which designates every contract made for the purpose of public utility…between the Spanish government and private individuals."
The asiento system was established following Spanish settlement in the Caribbean, when the indigenous population was undergoing demographic collapse and the Spanish needed another source of labor. Initially a few Christian Africans born in Iberia were transported to the Caribbean. But as the indigenous demographic collapse was ongoing and opponents of Spanish exploitation of indigenous labor grew, including that of Bartolomé de Las Casas, the young Hapsburg king Charles I of Spain allowed for the direct importation of slaves from Africa (bozales) to the Caribbean. The first asiento for selling slaves was drawn up in 1518, granting a Flemish favorite of Charles, Laurent de Gouvenot, a monopoly on importing enslaved Africans for eight years with a maximum of 4,000. Gouvenot promptly sold his license to Genoese merchants in Andalusia for 25,000 ducats. The crown controlled both trade and immigration to the New World, excluding Jews, conversos, Muslims, and foreigners. African slaves were considered merchandise, and their import regulated by the crown. Spain had neither direct access to the African sources of slaves nor the ability to transport them, so the asiento system was a way to ensure a legal supply of Africans to the New World, which brought revenue to the Spanish crown.
For the Spanish crown, the asiento was a source of profit. "The asiento remained the settled policy of the Spanish government for controlling and profiting from the slave trade." In Hapsburg Spain, asientos were a basic method of financing state expenditures: "Borrowing took two forms – long-term debt in the form of perpetual bonds (juros), and short-term loan contracts provided by bankers (asientos). Many asientos were eventually converted or refinanced through juros."
Initially, since Portugal had unimpeded rights in West Africa via its 1494 treaty it dominated the European slave trade of Africans. Before the onset of the official asiento in 1595, when the Spanish monarch also ruled Portugal in the Iberian Union (1580-1640), the Spanish fiscal authorities gave individual asientos to merchants, primarily from Portugal, to bring slaves to the Americas. For the 1560s most of these slaves were obtained in the Upper Guinea regions, especially in the Sierra Leone region where there were many wars associated with the Mande invasions.
Following the establishment of the Portuguese colony of Angola in 1575, and the gradual replacement of São Tomé by Brazil as the primary producers of sugar, Angolan interests came to dominate the trade, and it was Portuguese financiers and merchants who obtained the larger scale, comprehensive asiento that was established in 1595 during the period of the Iberian Union. The asiento was extended to importation of African slaves to Brazil, with those holding asientos for the Brazilian slave trade often also trading slaves in Spanish America. Spanish America was a major market for African slaves, including many of whom exceeded the quota of the asiento license and illegally sold. Most smuggled slaves were not brought by freelance traders.
Angolan dominance of the trade was pronounced after 1615 when the governors of Angola, starting with Bento Banha Cardoso, made alliance with Imbangala mercenaries to wreak havoc on the local African powers. Many of these governors also held the contract of Angola as well as the asiento, thus insuring their interests. Shipping registers from Vera Cruz and Cartagena show that as many as 85% of the slaves arriving in Spanish ports were from Angola, brought by Portuguese ships. The earlier asiento period came to an end in 1640 when Portugal revolted against Spain, though even then the Portuguese continued to supply Spanish colonies.
In the 1650s after Portugal achieved its independence from Spain, Spain denied the asiento to the Portuguese, whom they considered rebels. Spain sought to enter the slave trade directly, sending ships to Angola to purchase slaves. It also toyed with the idea of a military alliance with Kongo, the powerful African kingdom north of Angola. But these ideas were abandoned and the Spanish returned to Portuguese and then Dutch interests to supply slaves. The Spanish awarded large contracts for the asiento to the Dutch West India Company in 1675 rather than Portuguese merchants in the 1670s and 1680s. In 1700, with the death of the last Hapsburg monarch, Charles II of Spain, his will named the French House of Bourbon as the successor to the Spanish throne. The asiento was granted in 1702 to the French Guinea Company, for the importation of 48,000 African slaves over a decade. The Africans were transported to French Caribbean colonies of Martinique and Saint Domingue.
Britain disputed the Bourbon inheritance of the Spanish throne and fought in the War of the Spanish Succession. Although Britain did not prevail, it did receive the asiento as part of the Treaty of Utrecht. The asiento became a conduit for British contraband trade all kinds, which undermined Spain's attempts to keep a closed trading system with its colonies. The asiento agreement with the British survived until 1750, when Spain was implementing a number of administrative and economic reforms. The crown bought out the South Sea Company's right to the asiento in 1750. The crown sought another way to supply African slaves, attempting to liberalize its traffic, trying to shift to a system of the free trade in slaves by Spaniards and foreigners in particular colonial locations. These were Cuba, Santo Domingo, Puerto Rico, and Caracas, all of which used African slaves in large numbers.
British South Sea Company
At the conclusion of the War of the Spanish Succession, the Treaty of Utrecht gave to Great Britain a thirty-year asiento or contract, to send one merchant ship to the Spanish port of Portobelo, furnishing 4800 slaves to the Spanish colonies. This provided British traders and smugglers with inroads into the supposedly closed Spanish markets in America. Disputes connected with it led to the War of Jenkins' Ear (1739). Britain gave up its rights to the asiento after the war, in the 1750 Treaty of Madrid.
Similar patents in the English system were the Virginia Company, the Levant Company and the Merchant Adventurers' patent of trade with the United Provinces (essentially concurrent with the modern day Netherlands). A detailed and well written overview of the English system is given by Robert Brenner in "Merchants and Revolution".
