Lech II le Noir
The third Mongol invasion of Poland was carried out by Nogai Khan and Talabuga in 1287–1288. As in the second invasion, its purpose was to loot Lesser Poland, and to prevent Duke Leszek II the Black from interfering in Hungarian and Ruthenian affairs. The invasion was also part of the hostilities between Poland and Ruthenia; in 1281, the Poles had defeated a Mongol force near Goslicz which had entered Duke Leszek's territory in support of Lev I.
