In Harper Lee’s book “To Kill a Mockingbird,” she looks at how people of different races are treated unfairly, especially in the southern United States in the 1930s. This is shown mainly through the story of Tom Robinson, a black man who is wrongly said to have attacked a white woman.

One important part is when Atticus Finch, a white lawyer, tries to prove Tom is innocent. Even though he knows many people are biased against black people, Atticus fights for Tom. This shows how the law and society often judge people just because of their race, not because of the facts.

Another important character is Calpurnia, who works for the Finch family and is black. She helps the white family understand the black community better and shows how complicated it is when people are separated by race.

Her character shows how people are treated differently and have different chances in life because of their race, even in a small town. Also, Scout Finch, the main character who is a young girl, helps readers see how kids start to form ideas about race and unfairness. Scout’s friendships with other kids and the events during Tom Robinson’s court case help her learn about race and fairness, which shows what people thought back then. Overall, “To Kill a Mockingbird” is a strong message about unfair treatment because of race, showing how strong these unfair ideas are in people and towns, and how hard it is to change these ideas to make things fair and equal for everyone.
