  • The League of Nations and the Abyssinian Crisis (1934–1936)
  • Why the League Failed Africa: Causes and Consequences
  • The Organization of African Unity (OAU): Objectives, Structure and Record

The League of Nations was set up in 1920 to keep peace between countries after the First World War. Its members promised collective security collective security — if one state attacked another, all members would act together against the aggressor. Africa gave the League its sternest test of the 1930s: the invasion of Abyssinia (modern Ethiopia) by Fascist Italy under Benito Mussolini.

Abyssinia was one of only two independent African states in 1934 (with Liberia) and a League member since 1923. Mussolini wanted an East African empire to link Italian Somaliland and Eritrea, to avenge Italy's humiliating defeat by Abyssinian forces at the Battle of Adwa in 1896, and to boost his popularity at home with a cheap colonial victory.

The Wal-Wal Incident (December 1934): A clash between Italian and Abyssinian troops at the Wal-Wal oasis, well inside Abyssinian territory, left over 100 Abyssinians dead. Mussolini used it as a pretext for war. Emperor Haile Selassie appealed directly to the League, asking for arbitration and, later, for the League to act under its own Covenant.
  • October 1935 — Italy invades Abyssinia without a formal declaration of war, using aircraft, tanks and mustard gas against poorly armed defenders.
  • League response — the League declared Italy the aggressor and voted for economic sanctions economic sanctions, banning arms sales and some loans to Italy.
  • The gap in sanctions — oil, coal and steel were left off the sanctions list, and the Suez Canal (controlled by Britain) stayed open to Italian troop ships.
  • Hoare-Laval Pact (December 1935) — Britain's Samuel Hoare and France's Pierre Laval secretly agreed to give Mussolini two-thirds of Abyssinia to keep Italy as an ally against Hitler; the plan leaked and both men resigned in disgrace.
  • May 1936 — Italian forces capture Addis Ababa; Haile Selassie goes into exile and makes a famous speech to the League in Geneva, warning that 'it is us today, it will be you tomorrow.'

By July 1936 the League had quietly lifted its sanctions. Abyssinia had been conquered, and the League had failed its most public test since Manchuria in 1931.

The League's failure over Abyssinia was not one mistake but a chain of weaknesses that had been building for years. Understanding why it failed matters as much as what happened, because Paper 3 essays reward explained causation, not just narrated events.

Cause of failureHow it worked
No independent armyThe League relied on member states to supply troops or enforce sanctions voluntarily; it had no force of its own to stop Italy.
Britain and France prioritized EuropeBoth feared pushing Mussolini into an alliance with Hitler, so they avoided sanctions (like oil) that might actually cripple Italy.
Self-interest over principleBritain kept the Suez Canal open to Italian ships despite condemning the invasion — actions did not match words.
USA was not a memberThe League's founder, President Wilson, never got Senate approval to join; the world's largest economy could trade with Italy outside League control.
Precedent of Manchuria (1931)Japan had already invaded Manchuria and left the League unpunished, showing aggressors that defiance carried little cost.
The core exam argument: The Abyssinian Crisis exposed that the League's authority depended entirely on the willingness of its powerful members to enforce it. When Britain and France put their own diplomacy with Italy first, the League's credibility as a guardian of collective security collapsed — for Africa and for Europe.
  • For Abyssinia — occupation lasted until 1941, when British and Commonwealth forces (with Abyssinian resistance fighters) restored Haile Selassie during the Second World War.
  • For the League — its failure to stop Italy convinced Hitler that aggression could go unpunished, encouraging his own expansion into the Rhineland (1936) and beyond.
  • For Africa's image internationally — the crisis showed African states that appeals to European-led bodies could be ignored when it suited the great powers, a lesson that shaped post-1945 demands for African-run organizations.
Link forward in your essay: If your question asks about why African states later built their own organizations (like the OAU), the Abyssinian Crisis is your strongest opening evidence: it showed Africa that it could not rely on European-dominated bodies to defend African sovereignty.

By the early 1960s, decolonization had produced dozens of new independent African states. Leaders like Kwame Nkrumah of Ghana pushed for Pan-Africanism Pan-Africanism — full political union. Others, led by figures such as Haile Selassie (by then restored as Emperor of Ethiopia), wanted looser cooperation that respected each state's new sovereignty. The compromise was the Organization of African Unity (OAU), founded in Addis Ababa on 25 May 1963 with 32 founding member states.

1

Objectives

Promote unity and solidarity among African states, defend their sovereignty and territorial integrity, eradicate all forms of colonialism, and coordinate cooperation in economics, defence, health and science.

2

Structure

An Assembly of Heads of State and Government (the top decision-making body, meeting annually), a Council of Ministers, and a General Secretariat based in Addis Ababa running day-to-day administration.

3

Key rule: the Cairo Declaration (1964)

Members agreed to respect the colonial-era borders they inherited at independence, even though those borders had been drawn by European powers with no regard for ethnic groups — this was meant to prevent border wars between new states.

Unity, Sovereignty, Decolonization — the OAU's three pillars.

OAU Successes

  • Gave African states a single diplomatic voice at the UN and in world affairs
  • Coordinated support (funding, training, diplomatic pressure) for liberation movements still fighting colonial rule, e.g. in Angola, Mozambique and Zimbabwe
  • The Cairo Declaration border rule prevented many potential border wars between new states
  • Provided a forum for African leaders to mediate disputes without outside interference

OAU Failures

  • The rule of non-interference in members' internal affairs meant the OAU rarely condemned dictators or human rights abuses (e.g. it stayed largely silent on Idi Amin's Uganda)
  • It had no peacekeeping force of its own and no power to enforce its decisions
  • It failed to prevent or resolve conflicts such as the Nigerian Civil War (1967–1970) and later the Rwandan Genocide (1994)
  • Chronic underfunding — many members did not pay their dues, weakening the Secretariat
Compare with the League: Like the League of Nations, the OAU relied on voluntary member cooperation and had no independent force — a structural weakness it shared with the earlier organization, even though its goals (African unity and anti-colonialism) were very different.
What replaced it: The OAU was replaced by the African Union (AU) in 2002, which took on a stronger mandate including the right to intervene in members' affairs in cases of genocide — a direct response to the OAU's failure over Rwanda.
