They are like cousins to Zimbabweans, wouldn't be independent without them. Anyway almost all ethnic groups in Mozambique are found in neighbouring countries, present day Zimbabweans (Monomotapa) used to control vast parts of Mozambique. Shangaan are found in Mozambique, SA and Zim and they have a large Shona population. Angola is a little bit weird in that the combination of mestizos and so called assimilated blacks became more prominent than in Mozambique. There are few share of black Angolans who completely lost their language and culture and replaced it with Portuguese.
