Rwanda was the most densely populated country in Africa. It is two-thirds the size of Switzerland but contained a larger population (9 million people), growing by almost 40% every two years. Few square inches are left uncultivated. The Tutsi people (never more than 14% of the population) are said to have arrived in the 14th century ad, bringing with them a feudal and totalitarian system of government. There was significant intermarriage with the result that today the Hutu and Tutsi people share the same language, cultural beliefs and religions (predominantly Catholic). In reality the terms Hutu and Tutsi now more accurately describe caste than ethnicity (Delcros, 1994).
