Ooh South Africa had 11 Official Languages, but I believe we recently added SA Sign Language to make 12! This isiZulu language is the main one on the Eastern coast of South Africa, but the isiXhosa language which is more widely spoken where I'm from (Cape Town) is quite similar. Some of the other languages in the interior and northern parts of South Africa actually sound pretty different - last week's song I attempted one of those!!
I suppose it is up for debate whether South Africa should be one country, or divided up into several countries instead...
The Zulu were especially formidable warriors since the time of the famous King Shaka Zulu. He invented a shorter spear (for stabbing rather than throwing), and he also was a master of tactics and surrounding an enemy. Before his time, the Zulu was actually a relatively small tribe. After he came along, the Zulu took over the entire region, with many other clans/tribes having to retreat and resettle in various directions.
I believe this history affects our Politics to this day.
