Otto II the Strict

Otto II the Strict (c. 1266–1330) of the House of Welf was Prince of Lüneburg from 1277, ruling under his uncles' guardianship until 1282. His reign was filled with feuds over border and property disputes, financed by pledging estates; he curbed knightly rights and kept the peace.

He granted town rights to Dahlenburg in 1289 and Celle in 1292 and bought the County of Wölpe in 1302. After a disputed royal election, he allied with Louis of Bavaria, who granted him an imperial fief in 1315, and that year Otto issued a law of succession for his sons Otto and William. He died in 1330.
