Article 119 of the Treaty of Versailles took Germany's colonies away; the League of Nations decided what should become of them. The victors were not allowed simply to annex them. Instead each territory was entrusted to a "mandatory" power, which promised in writing to govern in the interest of the inhabitants and to report every year to the League. Ruanda-Urundi became a Belgian mandate in 1922. Read two articles of that mandate, then test them against what Belgium actually did in Rwanda.

Source: the Mandate for Ruanda-Urundi (confirmed by the League Council, 20 July 1922)
Article 3. "The Mandatory shall be responsible for the peace, order and good government of the territory, and shall undertake to promote to the utmost the material and moral well-being and the social progress of its inhabitants."
Article 5 (extract). "The Mandatory: […] 3) shall prohibit all forms of forced or compulsory labour, except for public works and essential services, and then only in return for adequate remuneration; 4) shall protect the natives from measures of fraud and force by the careful supervision of labour contracts and the recruiting of labour […]."
Text of the mandate as reproduced in the convention between the United States and Belgium on Ruanda-Urundi (United States Treaty Series No. 704, signed 1923–24), published in Papers Relating to the Foreign Relations of the United States, 1923, volume I (U.S. Government Printing Office).
Two features stand out. The mandate speaks of the inhabitants' "well-being" and "social progress", language that no pre-war colonial treaty had used. But it leaves a large exception in Article 5: forced labour was allowed for "public works and essential services", and the mandatory power itself decided what counted as essential and what remuneration was "adequate". As you read on, ask whether Belgium kept the promise of Article 3 and the limits of Article 5.
Definition
Mandatory power: the state given a mandate by the League, responsible for governing the territory and reporting on it.
Class A, B and C mandates: A mandates (former Ottoman lands such as Iraq, Syria and Palestine) were judged close to independence; B mandates (most of former German Africa, including Ruanda-Urundi and Tanganyika) were to be governed directly by the mandatory with guarantees for the inhabitants; C mandates (South West Africa and the Pacific islands) could be run as part of the mandatory's own territory.
Permanent Mandates Commission: the League's committee of experts in Geneva that examined each mandatory's annual report and petitions from the territories, and advised the Council.
Akazi: the unpaid forced labour that the Belgian administration required of Rwandans, organised through the chiefs, on roads, plantations and public works.
Identity card: here, the official document issued from the 1930s that recorded each Rwandan as Hutu, Tutsi or Twa and was passed from father to children.
The mandates were the League's answer to a contradiction: the Allies had promised self-determination, yet they had no intention of giving up the colonies they had conquered. Every mandatory sent an annual report to the Permanent Mandates Commission, whose members questioned its representatives in Geneva. Inhabitants could petition the League, but petitions had to be sent through the mandatory power itself, and the Commission never visited the territories. Its only weapon was publicity. The historian Susan Pedersen, in The Guardians (2015), argues that this oversight did not change colonial rule much, but it forced the powers to justify themselves in public, and the language of "trust" it created was later used by African nationalists against them.
Under the Orts–Milner agreement of 1919 Belgium agreed that Gisaka, in eastern Rwanda, should pass to British Tanganyika, where Britain hoped to build a Cape-to-Cairo railway. It was handed over in 1921. Mwami Yuhi V Musinga refused to accept the loss, and the Catholic mission supported him. In 1923 Belgium and Britain, with the League Council's approval, agreed to return Gisaka, and from 1 January 1924 the border ran along the Kagera River. Bugufi, part of Urundi, stayed in Tanganyika. The episode shows both how lightly Europeans redrew African kingdoms and how African rulers could use the new international system to resist.
Belgium governed through the Mwami and the chiefs, but from 1926, under Governor Charles Voisin, it reshaped the system. The old arrangement in which a district might have separate chiefs for land, cattle and men was abolished, chiefdoms were merged, and most Hutu chiefs were removed and replaced by Tutsi ones. Belgian officials and Catholic missionaries justified this with racial theories, invented in Europe and false, that ranked Rwandans by supposed origin. Those theories were never true, but the policies built on them gave a small Tutsi elite administrative power, while ordinary Tutsi, Hutu and Twa alike carried the burden of the colonial demands.
Rwandans had to provide unpaid labour (akazi), pay a head tax, and grow compulsory crops: food crops such as cassava and sweet potatoes against famine and, from the early 1930s, coffee for export. Despite the anti-famine crops, the Rwakayihura famine of 1928–29 struck hard, and thousands of Rwandans left to work in British Uganda or in the mines of Katanga in the Belgian Congo. Compare this with Article 5 of the mandate: the labour was neither limited to essential works nor adequately paid.
Musinga resisted Christian conversion and Belgian control; in November 1931 the administration deposed him and installed his son, Mutara III Rudahigwa, who became a Christian. Catholic conversions then rose rapidly in the 1930s. In 1933–34 a census recorded every Rwandan as Hutu, Tutsi or Twa, and the identity cards that followed fixed this category on each person and passed it to their children. Hutu, Tutsi and Twa had been social categories, and a person's position could change with wealth, marriage or service; the cards turned them into fixed, inherited labels. Historians regard these colonial policies as part of the long background to the divisions later exploited by the planners of the 1994 Genocide against the Tutsi. Unit 8 returns to this history.

Warning
Use exact and respectful language. Describe Hutu, Tutsi and Twa as social categories that Belgian policy hardened into fixed labels, not as "races" or "tribes" with separate origins. When you mention the racial theories of colonial officials, say clearly that they were false. And name the genocide exactly: the 1994 Genocide against the Tutsi.
Tip
Promise against practice. A strong answer on the mandates sets the words of the mandate (Articles 3 and 5) against evidence of practice (akazi, compulsory crops, famine, the identity cards, the deposition of Musinga), then weighs the limited value of League oversight (the return of Gisaka, the need to report). This structure works for any question that asks you to "assess" a colonial system.
Important
Discuss. The mandate promised to promote "the material and moral well-being and the social progress" of Rwandans. Using evidence from 1922 to 1939, did Belgium keep that promise? Was international supervision through the League better than no supervision at all?
