Civitas Schinesghe, meaning "Gniezno State", is the first recorded name related to Poland as a political entity, dating to the year 991 and attested to in a later papal regesta called Dagome iudex from 1080.

[1][2] Though the proper Latin name for Poland, Polonia, which came into use some time later, is not explicitly used in the document, the name Schinesghe presumably refers to Gniezno, which was one of the main gord strongholds of the West Slavic tribe of Polans.

[4] According to Gallus Anonymus, it was Mieszko's first wife, Dobrawa, the daughter of Boleslaus I, Duke of Bohemia, who convinced her husband to convert to Christianity.

The regesta titled Dagome iudex first defined Poland's geographical boundaries with its capital in Gniezno and affirmed that the state was under the protection of the Popes.

He also expanded the borders of the early Polish state by taking Lusatia, Moravia, Upper Hungary, and Red Ruthenia.
