New Netherlanders were not necessarily Dutch, and New Netherland was never a homogeneous society. Governor Peter Minuit was a Walloon born in Germany who spoke English and worked for a Dutch company. The term New Netherland Dutch generally includes all the Europeans who came to live there, but may also refer to Africans, Indo-Caribbeans, South Americans, and even the Indians who were integral to the society. Dutch was the official language and likely the lingua franca of the province, although other languages were also spoken. There were various Algonquian languages; Walloons and Huguenots tended to speak French, and Scandinavians and Germans brought their own tongues. It is likely that the Africans on Manhattan spoke their mother tongues but were taught Dutch from 1638 by Adam Roelantsz van Dokkum. The arrival of refugees from New Holland in Brazil may have brought speakers of Portuguese, Spanish, and Ladino (with Hebrew as a liturgical language). Commercial activity in the harbor could have been transacted simultaneously in any of a number of tongues.
