The period of rule by the Piast dynasty between the 10th and 14th centuries is the first major stage of the history of the Polish nation. The dynasty was founded by a series of dukes listed by the chronicler Gallus Anonymous in the early 12th century: Siemowit, Lestek and Siemomysł. It was Mieszko I, the son of Siemomysł, who is now considered the proper founder of the Polish state at about 960 AD. The ruling house then remained in power in the Polish lands until 1370.

He also completed a unification of the West Slavic tribal lands that was fundamental to the existence of the new country of Poland.
