Ruanda-Urundi

A Belgian Congo stamp overprinted for the Belgian Occupied East African Territories in 1916

World War I broke out in 1914. German colonies were originally meant to preserve their neutrality as mandated in the Berlin Convention, but fighting soon broke out on the frontier between German East Africa and the Belgian Congo around Lakes Kivu and Tanganyika.[2] As part of the Allied East African Campaign, Ruanda and Urundi were invaded by a Belgian force in 1916.[2] German forces in the region were small and hugely outnumbered. Ruanda was occupied over April–May and Urundi in June 1916. By September, a large portion of German East Africa was under Belgian occupation reaching as far south as Kigoma and Karema and as far eastwards as Tabora all in modern-day Tanzania.[2] In Ruanda and Urundi, the Belgians were welcomed by some civilians, who were opposed to the autocratic behaviour of the kings.[2] In Urundi, much of the population fled or went into hiding, fearful of war.[3] Much of the Swahili trader community which resided along the shores of Lake Tanganyika fled towards Kigoma, as they had long been commercial rivals with Belgian traders and feared retribution.[4] The territory captured was administered by a Belgian military occupation authority ("Belgian Occupied East African Territories") pending an ultimate decision about its political future. An administration, headed by a Royal Commissioner, was established in February 1917 at the same time as Belgian forces were ordered to withdraw from the Tabora region by the British.

While the Germans had begun the practice of conscripting labour from the Ruandans and Urundians during the war, this was limited since the German administration considered sustaining a local labour force logistically challenging. The Belgian occupation force expanded labor conscription;[5] 20,000 men were drafted act as porters for the Mahenge offensive, and of these only one-third returned home.[6] Many died due to malnourishment and disease.[7] The new labour practices caused some locals to regret the departure of the Germans.[8]

The Treaty of Versailles in the aftermath of World War I divided the German colonial empire among the Allied nations. German East Africa was partitioned, with Tanganyika allocated to the British and a small area allocated to Portugal. Belgium was allocated Ruanda-Urundi even though this represented only a fraction of the territories already occupied by the Belgian forces in East Africa. Belgian diplomats had originally hoped that Belgian claims in the region could be traded for Portuguese territory in Angola to expand the Congo's access to the Atlantic Ocean but this proved impossible. The League of Nations officially awarded Ruanda-Urundi to Belgium as a B-Class Mandate on 20 July 1922. The mandatory regime was also controversial in Belgium and it was not approved by Belgium's parliament until 1924.[9] Unlike colonies which belonged to its colonial power, a mandate was theoretically subject to international oversight through the League's Permanent Mandates Commission (PMC) in Geneva, Switzerland. Administratively, the mandate was divided into two pays, Ruanda and Urundi, each under the nominal leadership of a Mwami. The city of Usumbura and its adjoining townships were classified separately as centres extra‑coutumiers, while the pays were subdivided into territories.[10]

After a period of inertia, the Belgian administration became actively involved in Ruanda-Urundi between 1926 and 1931 under the governorship of Charles Voisin. The reforms produced a dense road-network and improved agriculture, with the emergence of cash crop farming in cotton and coffee.[11] However, four major famines did ravage parts of the mandate after crop failures in 1916–1918, 1924–26, 1928–30 and 1943–44. The Belgians were far more involved in the territory than the Germans, especially in Ruanda. Despite the mandate rules that the Belgians had to develop the territories and prepare them for independence, the economic policy practised in the Belgian Congo was exported eastwards: the Belgians demanded that the territories earn profits for their country and that any development must come out of funds gathered in the territory. These funds mostly came from the extensive cultivation of coffee in the region's rich volcanic soils.

To implement their vision, the Belgians extended and consolidated a power structure based on indigenous institutions. In practice, they developed a Tutsi ruling class to formally control a mostly Hutu population, through the system of chiefs and sub-chiefs under the overall rule of the two Mwami. Belgian administrators were influenced by the so-called Hamitic hypothesis which suggested that the Tutsi were partially descended from a Semitic people and were therefore inherently superior to the Hutu who were seen as purely African.[12] In this context, the Belgian administration preferred to rule through purely Tutsi authorities therefore further stratifying the society on ethnic lines. Hutu anger at the Tutsi domination was largely focused on the Tutsi elite rather than the distant colonial power.[13] Musinga was deposed by the administration as mwami of Ruanda in November 1931 after being accused of disloyalty.[14] He was replaced by his son Mutara III Rudahigwa.

Although promising the League it would promote education, Belgium left the task to subsidised Catholic missions and mostly unsubsidised Protestant missions. Catholicism expanded rapidly through the Rwandan population in consequence. An elite secondary school, the Groupe Scolaire d'Astrida was established in 1929 but as late as 1961, shortly before independence arrived, fewer than 100 Africans had been educated beyond the secondary level.The policy was one of low-cost paternalism, as explained by Belgium's special representative to the Trusteeship Council: "The real work is to change the African in his essence, to transform his soul, [and] to do that one must love him and enjoy having daily contact with him. He must be cured of his thoughtlessness, he must accustom himself to living in society, he must overcome his inertia."[15]

The League of Nations was formally dissolved in April 1946, following its failure to prevent World War II. It was succeeded, for practical purposes, by the new United Nations (UN). In December 1946, the new body voted to end the mandate over Ruanda-Urundi and replace it with the new status of "Trust Territory". To provide oversight, the PMC was superseded by the United Nations Trusteeship Council. The transition was accompanied by a promise that the Belgians would prepare the territory for independence, but the Belgians felt the area would take many decades to be ready for self-rule and wanted the process to take enough time before happening.

In 1961 the Belgian administration officially renamed Ruanda-Urundi as Rwanda-Burundi.[16]

Independence came largely as a result of actions elsewhere. African anti-colonial nationalism emerged in the Belgian Congo in the late 1950s and the Belgian Government became convinced they could no longer control the territory. Unrest also broke out in Ruanda where the monarchy was deposed in the Rwandan Revolution (1959–1961). Grégoire Kayibanda led the dominant and ethnically defined Party of the Hutu Emancipation Movement (Parti du Mouvement de l'Emancipation Hutu, PARMEHUTU) in Rwanda while the equivalent Union for National Progress (Union pour le Progrès national, UPRONA) in Burundi attempted to balance competing Hutu and Tutsi ethnic claims. The independence of the Belgian Congo in June 1960 and the accompanying period of political instability further drove nationalism in Ruanda-Urundi and the assassination of the UPRONA leader Louis Rwagasore, also Burundi's crown prince, in October 1961 did not halt the movement. After hurried preparations which included the dissolution of the monarchy in the Kingdom of Rwanda in September 1961, Ruanda-Urundi became independent on 1 July 1962, broken up along traditional lines as the independent Republic of Rwanda and Kingdom of Burundi. It took two more years before the government of the two became wholly separate and two other years until the proclamation of the Republic of Burundi.
