Otto IV, Duke of Brunswick-Lüneburg

Otto IV, also known as Otto Crookleg or Otto the Lame (d 1446) Duke of Brunswick-Lüneburg, was Prince of Lüneburg from 1434 to 1446.

Otto the Lame


After the death of his father, Bernard, he took over as ruler of the Principality of Lüneburg jointly with his brother, Frederick the Pious. Their rule was marked by major building work to Celle Castle and also by numerous reforms which improved the legal situation of farmers vis-a-vis their local lords.


In 1425 Otto IV married Elisabeth of Eberstein (before 1415-1468) and had a daughter by her.
