The second diaspora was the result of the colonization of Asia and Africa, which led to the development of 'New Englishes', the second-language varieties of English. In colonial Africa, the history of English is distinct between West and East Africa. English in West Africa began with trade. particularly the slave trade. English soon gained official status in what are today Gambia, Sierra Leone, Ghana, Nigeria and Cameroon, and some of the pidgin and creoles which developed from English contact, including Krio (Sierra Leone) and Cameroon Pidgin, have large numbers of speakers now.
