Oda von Haldensleben

Oda von Haldensleben (before 978-1023) was the daughter of the count of the North March Theoderich or Dietrich. According to most accounts she was a nun who was abducted from the monastery of Kolbe by Mieszko I.

Oda and her sons by the duke (named as Dagome), ruler of the Polanen tribe appear in a clergy note 80 years after a supposed document known as Dagome Iudex.

This reference to the Dagome Iudex is by Poles considered to be the first document of Poland under the Piasts.

The papal reference to an earlier document mentions Dagome and Oda von Haldensleben and her husband Dagome and their sons only. It specifically does not mention Mieszko's previous son Boleslaw I.Therefore it rather seems to refer to the territories which Oda and her husband governed and not to the territory of the Polans, ruled by Boleslaw I and centuries later called Poland.
