Postcolonial wars in Rwanda and Burundi

These articles focus on the armed conflicts in the region in the modern-day states of Rwanda and Burundi and the eastern regions of the Republic of Congo starting in the years before independence from colonial rule in 1962, culminating in the Rwandan genocide in 1994 and continuing since then in the Kivu region of the Congo. The conflict has an ethnic and social dimension in the social hierarchical division of the population in Hutus (agriculturalists) and Tutsis (pastoralists), a social division which was aggravated by racist policies of the colonial rulers. The conflict includes dimensions of extra- and intrastate wars with foreign involvement as well as one-sided violence in the form of campaigns for ethnic cleansing and even attempts at genocide.

Note about search on a specific nation: results produced by this feature are incomplete and inconsistent and should be seen as a means to narrow down the list rather than anything else. Work is being done to correct mistakes and standardize the parameters. At the bottom of the list of countries are some nations that do not exist in a similar form today.

Note about search on a specific year: "ongoing armed conflict" does not imply that all of the conflicts presented for a specific year should be classified as war.

Note about search on a specific time period: finds all wars that started after a specific year (1st search parameter) and ended before a specific year (2nd param).

Note about categories: this new feature is currently being tested and the content of these categories may be incomplete or inconsistent. More categories will be added in the future.
