Dagome iudex is one of the earliest historical documents relating to
Poland. Poland is not mentioned by name, but reference is made to
Dagome and
Ote (
Mieszko I and his wife,
Oda von Haldensleben) and their sons in 991, placing their land (called "Schinesghe") under the protection of the
Apostolic See. The document's name derives from its opening words.
