How does the setting affect what is happening in this book?

The setting of my book To Kill a Mockingbird is in a small town called Maycomb in the early 1900s. The conflict is that a young black man was accused of raping a white woman. The setting ties into a lot with the story. Since it was around the 1930s African American people did not have many rights. They were not treated fairly, or even paid as much as the average person. Most white people treated them like they were outsiders who did not belong. The better majority of the people who lived in Maycomb were white. So when they heard of this crime, that was not true, they automatically turned against the black man and believed the woman. His case did not stand a chance simply because of the color of his skin. Today is different than back in the 1900s. African American people have just as many rights as we do. We are all treated the same and there isn't as much discrimination towards people of different races.
