Prior to European colonization, Rwanda was the site of one of the region's most complex monarchical systems. The earliest known inhabitants of the region now known as Rwanda were the Pygmy and Twa. Later, groups known as Hutus and Tutsis also settled in the same region.

In 1895 Rwanda became a German province. The Germans, however, were at first completely dependent on the existing government. The German authority kept the indigenous administration system by applying the same type of indirect rule established by the British Empire in the Ugandan kingdoms. After Germany's loss in World War I, the protectorate was taken over by Belgium with a League of Nations mandate. Belgian rule in the region was far more direct and harsh than that of the Germans. However, the Belgian colonizers did realize the value of native rule. Backed by Christian churches, the Belgians used the minority Tutsi upper class over lower classes of Tutsis and Hutus. Belgian-forced labor policies and stringent taxes were mainly enforced by the Tutsi upper class, whom the Belgians used as buffers against people's anger, thus further polarising the Hutu and the Tutsi. Many young peasants, in order to escape tax harassment and hunger, migrated to neighboring countries. They moved mainly to Congo but also to Ugandan plantations, looking for work.

After World War II Rwanda became a UN trust territory with Belgium as the administrative authority. Through a series of processes, including several reforms, the assassination of King Mutara III Charles in 1959 and the fleeing of the last Nyiginya clan monarch, King Kigeri V, to Uganda, the Hutu gradually gained more and more power until, upon Rwanda's independence in 1962, the Hutu held virtually all power.

In 1990, the Tutsi-dominated Rwandese Patriotic Front (RPF) invaded Rwanda from Uganda. During the course of the fighting, top Rwandese government officials, mainly Hutu, began secretly training young men into informal armed bands called interehamwe ("coming together"). Government officials also launched a radio station that began anti-Tutsi propaganda. The military government of Juvénal Habyarimana responded to the RPF invasion with pogroms against Tutsis, whom it claimed were trying to re-enslave the Hutus. In 1992 the government and the RPF signed a cease-fire agreement known as the Arusha accords in Arusha, Tanzania to form a power sharing government, but fighting between the two sides continued. The United Nations sent a peacekeeping force named the United Nations Assistance Mission for Rwanda (UNAMIR), under the leadership of Canadian General Roméo Dallaire. UNAMIR was vastly underfunded and under-staffed.

During the armed conflict, the RPF was blamed for the bombing of Kigali. These attacks were in reality done by the Hutu army as part of a campaign to create a reason for the genocide that was about to ensue. On April 6 1994, President Habyarimana was assassinated [1] when his Falcon 50 trijet was shot down while landing in Kigali. It remains unclear who was responsible for the assassination – most credible sources point to the presidential guard, spurred by Hutu nationalists fearful of losing power, although others believe that Tutsi rebels were responsible, possibly with the help of Belgian mercenaries. Over the next three months, the military and interehamwe militia groups killed between 500,000 and 1,000,000 Tutsis and Hutu moderates in the Rwandan Genocide. The RPF continued to advance on the capital, and occupied the northern, the east and the southern parts of the country by June. U.N. member states refused to answer UNAMIR's requests for increased troops and money. Meanwhile, French troops were dispatched to stabilize the situation under Opération Turquoise, but resulted in exacerbating the situation and evacuating only foreign nationals.

On July 4th, 1994, the war ended as the RPF entered the capital Kigali. In the resulting Great Lakes refugee crisis over 2 million Hutus fled the country after the war, fearing Tutsi retribution. Most have since returned, although some militias remained in the Democratic Republic of the Congo and became involved in the First Congo War and Second Congo War. In 1996, Rwanda and Uganda invaded eastern Congo in an effort to eliminate the interahamwe groups operating there and to gain influence in the region, sparking the First Congo War.

Today, Rwandans continue to struggle with the legacy of genocide. 2004 marked the ten year aniversary with a ceremony in Kigali. Rwandan genocidal leaders are on trial at the International Criminal Tribunal for Rwanda, in the Rwandan National Court system, and, most recently, through the informal Gacaca village justice program. The current Rwandan government, led by Paul Kagame has become increasingly militant and opposed to dissent
