Rwanda,
in east-central Africa, is surrounded by the Democratic Republic of
the Congo, Uganda, Tanzania, and Burundi. It is slightly smaller than
Maryland. Steep mountains and deep valleys cover most of the country.
Lake Kivu in the northwest, at an altitude of 4,829 ft (1,472 m), is
the highest lake in Africa. Extending north of it are the Virunga Mountains,
which include the volcano Karisimbi (14,187 ft; 4,324 m), Rwanda's highest
point.
The original inhabitants of Rwanda were the Twa, a Pygmy people who
now make up only 1% of the population. While the Hutu and Tutsi are
often considered to be two separate ethnic groups, scholars point out
that they speak the same language, have a history of intermarriage,
and share many cultural characteristics. Traditionally, the differences
between the two groups were occupational rather than ethnic.
