The Spanish Company was an English chartered company or corporate body established in 1530, and 1577, confirmed in 1604, and re-established in 1605 as President, Assistants and Fellowship of Merchants of England trading into Spain and Portugal,^[4] whose purpose was the facilitation and control of English trade between England and Spain through the establishment of a corporate monopoly of approved merchants.

The key passage in the 1605 royal charter of King James I which re-established the company is as follows:^[6]

"And for that divers persons our subjects being not brought up in merchandise or use of traffic, but altogether ignorant and inexpert as well in the order and rules of merchandise as in the laws and customs of the realms of Spain and Portugal, and in the customs, usages, tolls and values of moneys, weights and measures, and in all other things belonging to merchandise very necessary, through their ignorance and lack of knowledge do commit many inconveniences and absurdities (as we are informed) to the offence of us and our dear brother the king of Spain, we willing to prevent and meet with such inconveniences and intending to further and help the expert and exercised merchants in their lawful and honest trade, and to establish good order and government in the said trade, of our ample and abundant grace do grant unto the president, assistants and fellowship of merchants that they, and such only as be or shall be of this incorporation or free of this fellowship, shall enjoy the whole entire and only trade and traffic and the whole entire and only liberty, use and privilege of trading and trafficking and using the feat and trade of merchandise, by and through all the parts of Spain and Portugal, from the town of Fuenterrabia in the kingdom or province of Biscay along the coast of Spain or Portugal or either of them unto Barcelona and in all the islands adjoining or appertaining to the said realms, towards the south or west part thereof.

The 1605 charter gave the Company power to "make ordain and establish statutes, laws, constitutions and ordinances, so as the laws and constitutions be not contrary, repugnant or derogatory to any treaties, leagues, capitulations or covenants between us, our heirs and successors, and any other prince or potentate made or to be made, nor tending to the hindrance of the trade and traffic of any of the fellowship, behaving him or themselves duly and orderly as becometh good merchants of the fellowship, without any fraudulent or disordered attempts or practices, as well for the good rule and government of the president, assistants and fellowship as of all and singular other subjects of us, our heirs and successors intermeddling or by any means exercising merchandise, in the realms of Spain and Portugal".

The 1605 charter gave the Company power to tax merchandise both imported and exported by their members in such sum "as to them shall seem requisite and convenient for the common profit and sustentation of the necessary and reasonable stipend and other charges of the fellowship and corporation".

The 1605 charter gave the Company power to punish wrong-doers, to "chastise and correct by imprisonment or otherwise by fine, amercement or other reasonable punishment"

The 1605 charter forbade customs officers to allow export of goods to Spain or Portugal except by members of the Company: "We straightly charge and command all and singular customers, comptrollers and collectors of customs, poundage and subsidies, and all other officers within our port and city of London and elsewhere unto whom it shall appertain, that they their clerks or substitutes, shall not take entry of any goods wares or merchandises to be transported into Spain or Portugal, or make any agreement for any custom, poundage or other subsidy for any such goods, but only of such person and persons free of the fellowship by virtue of these our letters patents".

The 1605 charter gave the Company power to establish its own consuls and governors within the area of trade in order to: "administer unto (members) full speedy and expedite justice in all and every their causes, plaints and contentions amongst them in the dominions of Spain and Portugal, and to pacify, decide and determine all and all manner of questions discords and strifes amongst them in any of the realms of Spain and Portugal, moved or to be moved, for the better government of the merchants in Spain and Portugal..."
