Imperialism instilled a feeling of inferiority among colonized populations. In some cases, this feeling of inferiority has developed into a more complex psychological web of hatred and violence. Throughout history, powerful Western nations have consistently invaded weaker nations in Africa, Asia, Latin America, and the Caribbean. By subjugating people and turning them into subjugated populations, Western powers have oppressed these populations. Oppression then led to the transformation of the psychology of the oppressed. The prevailing injustice and inequality between colonizer and colonized consequently results in a mentality that rationalizes violence and hatred. This mentality derives from the feeling of prejudice exercised by the colonizer. Frantz Fanon, a French psychiatrist, explores the plethora of mental disorders that plagued many Algerians after years of fighting against French colonial rule. During the period of liberation, Fanon describes the war as a total war, a situation achieved only after increased frustrations and in which all members of society are affected and, therefore, involved. In essence, colonialism does not simply control foreign territory, but also controls the consciousness of the population. As observed in the aggressive behavior of French colonists towards Algerians, power and violence play an important role in influencing psychiatric disorders in oppressed populations. While the era of imperialism has supposedly ended, the era of globalization has continued the legacy. In essence, globalization serves as a softer euphemism for colonialism. These oppressed populations are still deprived of their identity due to the overwhelming influence of the op...... middle of paper ......colonial era and the onset of globalization, Western nations have felt the need to spread their culture to non-Western communities. After all, “superior” Western culture could only help the backward culture of non-Western peoples advance. At the same time, this led to the spread of Western treatment methods to many parts of the world in an attempt to homogenize diagnosis and treatment. As observed in Indonesia, Algeria, and Sri Lanka, local context played an important role in influencing psychiatric disorders. The symptomatology shown in these three cases contrasts with established Western thinking. Despite their differences, the West always feels the need to extend its ideas to the non-Western context to maintain its influence. Undermining local culture by reorienting their beliefs about trauma is the Western attempt to homogenize psychiatric thinking.
