[2][better source needed] Regelinda was married to Herman I shortly after his father Margrave Eckard I of Meissen was killed on April 30, 1002.

While Duke Bolesław had occupied the March of Lusatia and the Milceni lands, the marriage brought the Polish Piasts and the Ekkardiner margraves closer.

The alliance with the Polish ruler was renewed after the 1018 Peace of Bautzen, when Bolesław married Herman's sister Oda.

The margravine is better known for the 13th century statue erected in Naumburg Cathedral by the Naumburg Master, which shows a "smiling Polish woman" (Polish: śmiejąca się Polka, German: Lächelnde Polin).

It is part of a semicircle of twelve donor portraits in the west choir, among them Herman's brother Margrave Eckard II and his wife Uta, although there is some research which questions her identification.
