In the thirteenth century the principles of national law, especially that of the right of intervention on the part of one government in the struggles either of the sovereigns or the subjects of its neighbours, had not been as systematically laid down and defined as they are now. But the good sense and moral rectitude of St. Louis led him to follow the right path, and no temptation, not even his own fervent piety, ever induced him to swerve from it. It was his constant care not to allow either the State or Church of France to take any part in the struggle between the Papacy and the Empire, and he strove to uphold the dignity of his crown and the well-being of his subjects by using his influence to secure the establishment of a just and peaceful policy throughout Christendom.

Christian Europe And Mahometan Asia In The Thirteenth Century.
A just and peaceful policy throughout Christendom was the great need of Christianity in the thirteenth century, for it had to struggle with two enemies, and was exposed to two very formidable dangers.
The Crusaders had inaugurated a fierce and bitter struggle with the Mahometans in Asia; and towards the middle of the thirteenth century, in the very heat of the conflict, and from the depths of Asia itself, a barbarous and almost pagan people—the Mongol Tartars—spread like a foul flood over Eastern Europe. They swept over Russia, Poland, Hungary, Bohemia, and Germany, ravaging and threatening with total destruction every province through which they passed. M. Abel Rémusat has studied all the documents relating to these terrible invasions, which he describes with the accuracy of a scholar. He writes as follows:—
'According to the laws established by their first great chief Tchinggis Khan, the Mongols were commanded to show mercy to those princes and nations that gave proof of their submission by surrendering their towns and consenting to pay tribute. All others were given up to the fury of the soldiers, and massacred without distinction of age or sex, the very animals being often included in an indiscriminate slaughter. It was impossible to negotiate with the Tartars in their early invasions; men had either to submit or die, and countless pyramids of human bones, which they erected on the sites of ruined cities, testified to the danger of resistance. These ghastly monuments were to be seen long afterwards, and were the terror of our travellers who passed through the regions which the Tartars had swept over and made desolate.'
The chronicles of the thirteenth century describe the Tartars as—
'A terrible race rushing down from the mountains of the North; an impious multitude who fear nothing, believe nothing, and worship nothing but their king—him they call the great King of kings and Lord of lords; men, or rather brutes, who are relentless; monsters having nothing human about them; greedy for blood, and drinking it with delight; tearing and devouring the raw flesh of animals, of dogs—nay, even of human beings; having an enormous head on a misshapen body, huge chests, large arms and short strong legs; clothed in the skins of cattle, and armed with iron lances; untiring warriors, unequalled archers, and of astounding courage, riding on great and strong horses which are so swift that they can go three days' journey in one day, and require no other food than leaves and the bark of trees. These horses they mount by means of three stirrups suspended one from the other, for they need this ladder on account of the shortness of their legs; crossing the broadest and most rapid rivers without delay or difficulty by means of boats made of ox-hide which they carry about with them: and for the matter of that, it gives them no more trouble to swim than to eat' [Footnote 11]
