Lestek
9th/10th-century Duke of the Polans

Lestek (also Leszek, Lestko) was the second duke of Polans, and son of Siemowit, born c. 870–880, mentioned in the oldest Polish chronicle, Gesta principum Polonorum by Gallus Anonymus. The dukes of Polans were the foundation of the Piast dynasty, the first historical ruling dynasty of Poland.
Initially, no one doubted the historicity of Lestek. In the second half of the nineteenth century, however, his existence began to be questioned. The issue was basically settled thanks to an article written by Henryk Łowmiański, in which he came out in favor of the credibility of Gallus Anonymus's account, and thus in favor of the historicity of the three direct predecessors to Mieszko I. This view is dominant in the Polish historiography.
The origin of his name is not known, but it can be derived from the old Polish word lście which means "crafty". It is believed this is a diminutive of the Slavic name Lścimir or Lścisław. The number and existence of Lestek's wives or consorts are unknown. A theory by Stanisław Zakrzewski claims Lestek (or Lestko) could have been married to a Moravian princess.
