In Lorraine Hansberry's masterpiece, A Raisin in the Sun, we observe the violent behavior of black people against black people in the conflicts between black individuals. Racism can be defined as practices in which white-skinned people are discriminated against with derogatory attitudes that lead to violence, based on skin color, culture, language and religion, thinking that they are superior to black people. However, it is observed that racism occurs in many societies among people with the same values, depending on different factors. Based on this fact, it is not correct to define racism as a phenomenon that occurs only in black and white skin color. In Lorraine Hansberry's work, A Raisin in the Sun, the discrimination observed between family members, the reactions shown to establish authority, and the approaches of black community members towards each other reach a level that can be defined as racism. Racism, which appears in many ways, has gained a different dimension from the practices of blacks towards blacks. We learn many of these racist practices, described as New Racism or Black on Black Racism, from slave narratives, biographies or autobiographies written by Black writers. The racist practices of black people against black people will be tried to be determined in Hansberry's work, which depicts the lifestyle and conflicts of black people. Conflicts between people who have the same race, skin, religion, language, and culture reach the level of racism and even lead to slavery. The most concrete applications of this type of racism took place in Liberia, which was founded by America and England as the first independent country for black people in America who gained their freedom. In the Republic of Liberia, black people who gained freedom in America defined themselves as "American Africans" and continued their slavery practices on “African Africans" to whom they thought themselves superior. The study aims to find out the conflicts that resemble racist behaviors among the black individuals described in A Raising in the Sun, even if it is not at the level of racism in Liberia and point out that racist practices are based on many factors.
