 In 1241, after raiding Lesser Poland region, the Mongols invaded Europe and Silesia, causing widespread panic and mass flight.They looted much of the region and defeated the combined Polish and German forces under Henry II the Pious at the Battle of Legnica, which took place at Legnickie Pole near the Silsian city of Legnica.Upon the death of Orda Khan, the Mongols chose not to press forward further into Europe, but returned east to participate in the election of a new Grand Khan (leader).
