John II of Hoya

John II of Hoya (1319–1377) became ruling count in 1324 after his father Otto II's death, governing jointly with his brother Gerhard III. A former church canon, he married Helen of Saxony-Lauenburg in 1338. In 1345 the brothers divided their lands, John taking the Upper County and Gerhard the Lower County.

His rule saw the Hoya Feud against the city of Bremen, and late in life he joined Magnus II of Brunswick-Lüneburg in the Lüneburg War of Succession.
