Carl Sylvius Völkner, German-New Zealand priest and missionary (born 1819)

Carl Sylvius Völkner was a German-born Protestant missionary active in the North Island of New Zealand during the mid-nineteenth century. He is famous for being tried and executed for espionage by members of the Pai Mārire faith at his church in Ōpōtiki, in the Bay of Plenty. This later became known as the Völkner incident, an important event in the New Zealand Wars.
