Machine summary:
These troubles, together with the alliances concluded from time to time by Witold's successors with the various independent Khanates, were the reason for the uninterrupted Tatar emigration into Lithuania during the whole course of the fifteenth century.
Besides, as the Tatar emigrants on their arrival in Lithuania had hardly any women with them, Witold and his successors granted them the right to marry Christian women without changing their religion.
The Tatars who came to Lithuania as early as the fourteenth century, most of them as former allies, received a warm welcome ; the Lithuanian princes, and later, the kings of Poland, were glad to have at their disposal an element of population which was faithful, obedient, submissive to military service, and ready to fight at any moment.
The attachment of these emigrants to the religion and the traditions of their ancestors is so great that they have built a house of prayer, own a cemetery, and not only are in friendly relations with their Polish brethren, but largely contributed to the expenses for the repair of the mosques destroyed or damaged in the Great War. Although the persecutions against the Poles did not specially concern the Tatars, they did not stay aloof from the efforts of the Polish patriots who, under Marshal Pilsudski, struggled for the independence of their country.
