"On 12 April 965, Kaiser Otto I of Nordhausen granted from Saint John's Monastery to Magdeburg the honey tithe from the Slavic province of Nizzi lying in his faithful Hodo's county." .
The mention of the place Clotna in the year 965 allows the conclusion that Klöden is more than 1000 years old, as the document is witness to a fraudulent acquisition of a honey tithe, not to a founding date.
