The event which has been called the fifth crusade was not wanting, so far, in real importance, and it would have to be described here, if it had been really a crusade; but it does not deserve the name.

The crusades were a very different thing from wars and conquests; their real and peculiar characteristic was, that they should be struggles between Christianity and Islamism, between the fruitful civilization of Europe and the barbarism and stagnation of Asia.

Therein consist their originality and their grandeur.

It was certainly on this understanding, and with this view, that Pope Innocent III., one of the greatest men of the thirteenth century, seconded with all his might the movement which was at that time springing up again in favor of a fresh crusade, and which brought about, in 1202, an alliance between a great number of powerful lords, French, Flemish, and Italian, and the republic of Venice, for the purpose of recovering Jerusalem from the infidels.

But from the very first, the ambition, the opportunities, and the private interests of the Venetians, combined with a recollection of the perfidy displayed by the Greek emperors, diverted the new crusaders from the design they had proclaimed.
What Bohemond, during the first crusade, had proposed to Godfrey de Bouillon, and what the Bishop of Langres, during the second, had suggested to Louis the Young, namely, the capture of Constantinople for the sake of insuring that of Jerusalem, the first crusaders of the thirteenth century were led by bias, greed, anger, and spite to take in hand and accomplish; they conquered Constantinople, and, having once made that conquest, they troubled themselves no more about Jerusalem.
Founded, May 16th, 1204, in the person of Baldwin IX., Count of Flanders, the Latin empire of the East existed for seventy years, in the teeth of many a storm, only to fall once more, in 1273, into the hands of the Greek emperors, overthrown in 1453 by the Turks, who are still in possession.
One circumstance, connected rather with literature than politics, gives Frenchmen a particular interest in this conquest of the Greek empire by the Latin Christians; for it was a Frenchman, Geoffrey de Villehardouin, seneschal of Theobald III., Count of Champagne, who, after having been one of the chief actors in it, wrote the history of it; and his work, strictly historical as to facts, and admirably epic in description of character and warmth of coloring, is one of the earliest and finest monuments of French literature.
But to return to the real crusades.
At the beginning of the thirteenth century, whilst the enterprises which were still called crusades were becoming more and more degenerate in character and potency, there was born in France, on the 25th of April, 1215, not merely the prince, but the man who was to be the most worthy representative and the most devoted slave of that religious and moral passion which had inspired the crusades.
