Larger invasions of Poland, devoted primarily to looting, would be launched later. Led by Burundai, the Mongols successfully raided Poland in 1259–1260. They raided again under the leadership of Tulabuga and Nogai Khan, accompanied by vassal troops from Ruthenia, successfully in 1286 and unsuccessfully in 1287. Although the Mongols repeatedly expressed desire to conquer central Europe in ultimatums up to the 1270s, Poland and Hungary stayed outside of the Golden Horde's sphere of influence. The Russian lands to their east remained under the rule of the Golden Horde for the next two centuries.
