Lestko, Polish: Leszek is the second legendary duke of Poland, and son of Siemowit, born probably 930/940 Though proof of his actual existence is unclear, he had to have been a major figure in his time, due to the fact that before Poland existed as a state, the tribes that lived on its lands where referred to as "Lestkowici", which would suggest Lestko's influence over this area.
