The first diaspora involved relatively large-scale migrations of mother-tongue English speakers from England, Scotland and Ireland predominantly to North America and the Caribbean, Australia, South Africa and New Zealand. Over time, their own English dialects developed into modern American, Canadian, West Indian, South African, Australian, and New Zealand Englishes. In contrast to the English of Great Britain, the varieties spoken in modern North America and Caribbean, South Africa, Australia, and New Zealand have been modified in response to the changed and changing sociolinguistic contexts of the migrants, for example being in contact with indigenous Native American, Khoisan and Bantu, Aboriginal or Maori populations in the colonies.
