Frantz Fanon was a French writer and political philosopher who lived in the 20th century. He wrote books and articles that explored the effects of colonialism on people of color and argued that the only way to end racism and the unfairness of colonial rule was through violence. He traveled around the world, teaching people about their rights and how to fight for greater freedom, justice, and fairness. He also wrote about how colonialism affects people's mental health, and how to care for people facing racism, poverty, and other hardships. Fanon's ideas are still studied today because they help people to better understand how colonialism has shaped the world we live in and how to fight for change.
