In what ways were both Rwanda and South Africa divided?

Rwanda is a land-locked Country located in the central part of Africa. People began settling in the area as early as 10,000 BCE. After several successive waves of migrations Rwanda saw the formation of several smaller Kingdoms in the 1100s; and by the 1500s a larger and more centralized kingdom known as the Kingdom of Rwanda emerged. The Kingdom of Rwanda was ruled by the Mwami (King), and the kingdom reached the height of its territorial expansion in the late 1800s.
