At the Congress of Aix-la-Chapelle, in 1818, and of Verona, in 1822, Great Britain continued her intervention against Slavery. Chateaubriand, in his history of the latter Congress, pauses to express his admiration of the “singular perseverance” in this cause manifested by her at all Congresses, amidst questions the most urgent and interests the most pressing.[83] Here her primacy was undisputed, and her fame complete. It was the common remark of Continental publicists, that she “made the cause her own.”[84] One of them portrays her vividly, since 1810 waging “relentless war” against the principle of the slave-trade, and by this “crusade,” undertaken in the name of Humanity, making herself the “declared protectress” of the African race. These are the words of a French authority.[85] According to him, it is nothing less than “relentless war” and a “crusade” which she has waged, and the position which she has achieved is that of “protectress” of the African race,--while no less a person than Chateaubriand recognizes with admiration the “singular perseverance” she has displayed in this practical extension of Christianity. Not content with imposing her magnanimous system upon the civilized world, she carried it among the tribes and chiefs of Africa, who, by her omnipresent intervention, were summoned to renounce a barbarous and criminal custom. By a Parliamentary Report, it appears that in 1849 there were twenty-four treaties in force between Great Britain and foreign civilized powers for the suppression of the slave-trade, and also forty-two similar treaties between Great Britain and native chiefs of Africa.[86] This intervention was not by treaties only; it was by correspondence and circulars also. And here I approach a part of the subject which illustrates the vivacity of its character. All British ministers and consuls were so many pickets on constant guard in the outposts. They were held to every service by which the cause could be promoted, even to translating and printing documents against the slave-trade, especially in countries where, unhappily, it was still pursued. There was the Pope’s Bull of 1839, which Lord Palmerston transmitted for this purpose to his agents in Cuba, Brazil, and even in Turkey, some of whom were unsuccessful in their efforts to obtain its publication, although, curiously enough, it was published in Turkey.[87]
