Edexcel spec: Paper 2 Section B, Breadth study B5, Key topic 2

  • Why Japan invaded Manchuria in 1931 and what happened next
  • How China appealed to the League and what the Lytton Commission found
  • Why Japan left the League in 1933
  • Why the League did nothing more, and how this differed from its successes in the 1920s

In 1931 the League faced its first big test from a powerful country. Japan was a permanent member of the Council, and it invaded a neighbour that was also a League member. This lesson follows the Manchuria crisis from invasion to Japan's exit.

Key terms:

  • Manchuria: a large region of north-east China, rich in coal and iron.
  • Puppet state: a country that looks independent but is really controlled by another country.
  • Commission of enquiry: a group sent to investigate a dispute and report on what it finds.
  • Sovereignty: the right of a country to rule itself and its own land.

Why Japan invaded

Japan was a crowded island country with few raw materials. It had won the right to run the South Manchuria Railway after a war with Russia in 1904-05, and it kept troops (the Kwantung Army) in Manchuria to guard it. Japan also had large investments there.

The Great Depression hit Japan hard. Its trade, especially in silk, collapsed. Many Japanese people lost faith in the elected government, and army leaders argued that Japan needed Manchuria's coal, iron and farmland to be safe and rich. Some army officers were ready to act without waiting for orders from Tokyo.

The invasion, 1931-33

💥 September 1931

On 18 September 1931 came the Mukden incident: an explosion on the South Manchuria Railway near Mukden. Japanese officers blamed Chinese soldiers. The Kwantung Army used it as an excuse to seize Mukden, and over the next months it took control of the whole of Manchuria.

🎌 February 1932

Japan set up a new state called Manchukuo. Its head was Puyi, the last emperor of China, but Japan held the real power. The new state was a puppet state.

China appeals to the League

China was a League member. Within days of Mukden, in September 1931, it appealed to the League for help under the Covenant. The League's Council asked Japan to withdraw its troops. Japan said it would do so once its citizens were safe, but its army kept advancing. Japan claimed it was only protecting its own interests and its people.

In December 1931 the League decided to send a commission of enquiry, led by Lord Lytton from Britain. This was a slow process. The Lytton Commission travelled to Manchuria in 1932 and published its report in October 1932, by which time Japan controlled the whole region.

The Lytton report

What the Lytton report said

  • Japan had acted unlawfully by invading Manchuria, and Manchukuo was not a genuine independent state.
  • But it also accepted that Japan had real interests in Manchuria.
  • It suggested that Manchuria should be self-governing under Chinese sovereignty, with international advisers and a place for Japan's interests.

The report did not tell the League to punish Japan or to use sanctions or force. In February 1933 the League Assembly voted 42 to 1 to accept the report, with only Japan voting against. Japan then walked out of the meeting. In March 1933 it announced that it was leaving the League. Japan also went on to invade the neighbouring province of Jehol in early 1933, and in May 1933 China had to agree to a truce that left Japan in control.

Why the League did nothing more

  • No army. The League had no force of its own. Only Britain and France had the strength to act, and neither wanted to send ships and troops to the other side of the world.
  • Distance and self-interest. Manchuria was far from Europe. Britain and France put their own interests first and did not see their own security as at risk.
  • The Depression. Governments were busy with unemployment at home. Sanctions would hurt trade, and Japan was a major trading partner. The USA, which was not a League member, could not be forced to join in.
  • Slowness. The League took more than a year to produce a report. By then Japan had won, and the report had little power to make it leave.
  • Japan's status. Japan was a Great Power and a permanent member of the Council, so members were wary of taking on a strong country.

The result was a disaster for the League's reputation. It had shown that an aggressive Great Power could break the Covenant and get away with it. Mussolini and Hitler were watching.

Change and continuity

In the 1920s the League had stopped a dispute between small countries, such as the Greek-Bulgarian War of 1925. In 1931-33 it failed to stop a Great Power. What stayed the same was the League's reliance on its members, because it had no army of its own.

Common mistakes

  • Saying the League sent troops to Manchuria. It did not; it sent a commission of enquiry.
  • Saying the Lytton report backed Japan. It said Japan was in the wrong, though it recognised Japan's interests.
  • Writing that Japan was thrown out. Japan chose to leave, in March 1933.

Exam-style question

Explain TWO ways in which the League's response to the Japanese invasion of Manchuria (1931-33) was different from its response to the Greek invasion of Bulgaria in 1925. [6 marks]

Model answer

One difference is the outcome. In 1925 the Council, with Briand in the chair, ordered Greece to withdraw its troops from Bulgaria, and Greece obeyed and paid compensation of 45,000 pounds. In 1931-33, however, Japan ignored the League's calls to withdraw from Manchuria, set up the puppet state of Manchukuo and, in March 1933, left the League. So the League settled the Bulgarian crisis but failed to remove Japan.

A second difference is the speed and the target. In 1925 the League acted quickly against Greece, a smaller power that gave way to pressure from the Great Powers. In 1931-33 it set up the Lytton Commission in December 1931 and did not publish its report until October 1932. By then Japan, a Great Power and a permanent member of the Council, controlled the whole of Manchuria. The League's slow response against a strong country achieved nothing.

What lifts this to the top level: two different ways, each making a direct comparison with a precise fact about both sides.

Exam tip

In a "different from" question, write each way as a direct comparison: "In 1925 ... whereas in 1931-33 ...". A way that only describes one side gets few marks, and a single way scores at most 3 out of 6.

Recap

  • Japan invaded Manchuria after the Mukden incident of 18 September 1931 and set up the puppet state of Manchukuo in 1932.
  • China appealed to the League, which sent the Lytton Commission; its report (October 1932) said Japan was in the wrong but wanted a compromise.
  • The Assembly accepted the report 42 to 1 in February 1933, and Japan left the League in March 1933.
  • The League did nothing more because it had no army, was far away, was hit by the Depression and was unwilling to take on a Great Power.
