Belize Creole English or ''Kriol'' developed during the time of slavery, and historically was only spoken by former slaves. However, this ethnicity has become an integral part of the Belizean identity, and as a result it is now spoken by about 45% of Belizeans. Belizean Creole is derived mainly from English. Its substrate languages are the Native American language Miskito, and the various West African and Bantu languages brought into the country by slaves. Creoles are found all over Belize, but predominantly in urban areas such as Belize City, coastal towns and villages, and in the Belize River Valley.
