Set in the Depression-era of the 1930s where Blacks were still highly subjugated members of society, were not permitted to commingle with whites in public settings, as exemplified in the courthouse physical separation of races and the distinct black and white areas of town.
Throughout the novel, Scout explores the differences between black people and white people. An integral part of the book for me was the character Tom Robinson who is convicted purely because he is a Black man and his accuser is white. The evidence is so powerfully in his favor, that race is the single defining factor in the jury's decision. That courtroom scene
Getting an Education, Social Inequality, Racism, and Human morality are key themes of the book.
A classic indeed.
