the internal affairs of his Government is a violent usurpation of his authority, and an open declaration of the right of the strong over the weak.”[77] This was practically answered by Lord Clarendon, speaking for Great Britain at the Congress of Paris, when, admitting the principle that no Government has the right to interfere in the internal affairs of other states, he declares that there are cases where an exception to this rule becomes equally a right and a duty; that peace must not be broken, but that there is no peace without justice; and that therefore the Congress must let the King of Naples know its desire for the amelioration of his Government, and must demand amnesty for political offenders suffering without trial.[78] This language was bold beyond the practice of diplomacy, but the intervention it proposed was on the side of humanity. I must draw this chapter to a close, although the long list is not yet exhausted. Even while I speak, we hear of intervention by England and France in the civil war between the Emperor of China and his subjects,--and also in that other war between the Emperor of Russia on the one side and the Poles whom he claims as subjects on the other, but with this difference, that in China these powers take the part of the existing Government, while in Poland they intervene against the existing Government. In the face of positive declarations of neutrality, the British and French admirals have united their forces with the Chinese; but thus far in Poland, although there is no declaration of neutrality, the intervention is unarmed. In both these instances we witness a common tendency, directed, it may be, by the interests or prejudices of the time, and, so far as it has proceeded, it is, at least in Poland, on the side of liberal institutions. But, alas for human consistency! the French Emperor is now intervening in Mexico with armies and navies to build an imperial throne for an Austrian Archduke. * * * * *
