History Paper on Manchurian Invasion


The Japanese soldiers invaded Manchuria beginning September 1931. This led to the development of an institution within the temporary state known as Manchukuo. The institution lasted until the World War II was over. According to the Japanese history, it is still considered as the most vindictive and unkind act in the country[1]. The invasion however did not support the rules of the League of Nations. It therefore lacked war declarations hence, being considered against the rules of the League of Nations. Consequently, the Treaty of Portsmouth allowed Japan to own portion of South Manchuria Railway branch. As a result, Japanese realm had to invest heavily in the region. The investments were implemented in attempts to establish a heavy military base. This is because the base would be empowered and enabled to claim the place in order to provide security. The place however experienced an invasion. The invasion was triggered by a small dynamite explosion next to the Japanese railway line. The railway line was located south of the Manchuria railway[2]. The explosion however did not affect the Japanese train, which was on transit. The train was therefore released a few minutes later to complete the journey. Japan however located a base through which it accused the Chinese being responsible for the incident that was followed by the invasion.

Causes of Japanese Invasion of Manchuria

Manchuria was affected by World War 1 and the great depression. It however continued to offer useful resources such as minerals, forestry and rich land holds. There resources enabled Japan to achieve economic stability. More so, Japan was moved to invade the place as it offered solution to the existing economic stalemate. Thus, Manchurian assets including soybeans, salt, and landholdings were rigorously insufficient in the Japanese empire[3]. At the time, Japan was also experiencing increased foreign tariffs imposed on its exports that would not make it possible for them to pay for imports. The Japanese hard learnt also learnt that adequate natural assets were crucial in times of war. They learnt this from the World War 1.This greatly triggered them to invade to take over so as to have its future imminent.

Japan huge population increase was another factior that led to its invasion on Manchuria. Due its population growth, the empire could not adequately produce food to which the only solution was to invade expansive Manchuria. The populace had abandoned Japan with superfluous agricultural resources and a good number of emigrants. These expatriates were isolated against in the rest of the world, which triggered the invasion to settle its population.

Effects of the Invasion

China made a petition League of Nations concerning the Japanese act. The request was accepted and Japan was ordered to withdraw from Manchuria. However, considering the benefits it was accruing up from the invasion, Japan declined to honor the demand. They went further to deregister their association from the League of Nations. This resulted to Japan’s isolation from other treaty Nations. The League of Nations slapped Japan with sanctions m of trade restrictions with other empires, which were not enforced by its authority. This caused other influential member States including Germany and Italy to join Japan in opposing the rules implemented by the League of Nations. This exposed weak face of the league in relation to its strength on League Nations. As a result, it was regarded as weak in comparison to the strong Nations that emulated Japan’s aggressiveness among the neighbors[4].
