Whilst there, in May, 1815, Buckingham had the offer of the command of the _Humayoon Shah_, a vessel built at the Portuguese port of Damann, north of Bombay, by the Imaum of Muscat, for trade with China. The retiring captain, named Richardson, in three successive voyages had cleared £30,000, and the situation had been sought by several of the marine officers of the East India Company. When these disappointed men heard that Buckingham had secured the appointment, they were angry, and applied to the Company to eject him from India and close every port there in their power against him. This they did by refusing him a licence to remain in India. The British Government, in granting a charter of exclusive trade to India and China to the East India Company, gave that Company thereby a right to expel from their dominions all British-born subjects who had not their licence to reside there, this being deemed necessary to protect them from the competition of "interlopers" as they were called, who might undersell them in their own markets. But though the British Government might thus condemn all the twenty million of its own native-born subjects to this state of ignominious dependence on the will or caprice of a handful of monopolists, a body of some twenty-four directors only--in whose hands lay the power of granting licences or banishing those who did not possess them--it could not authorize the exercise of such powers against the natives of any foreign state; consequently James Silk Buckingham was advised to become nationalized as an American citizen, in which case the East India Company would be powerless to expel him. In point of fact, the case stood thus: all foreigners who had no natural claim on India as a part of their dominions might visit it freely and reside and trade in it as long as they pleased, without licence from its rulers; whereas British-born subjects, who had contributed by their payment of taxes to support the very Government that made the charter, were unjustly excluded, although the conquest of India had been made by British blood and British treasure, and the country was still held under the British flag. In short, all foreigners were free men there, and the freeborn Englishman alone was a slave. Buckingham so felt the iniquity of this system that later, when he came to England, he agitated and wrote against the continuance of the charter.
