When did the trial in to kill a mockingbird take place?

To Kill a Mockingbird takes place in the fictional small Southern town of Maycomb in the 1930s (Tom's trial takes place in 1935). Slavery and the Civil War of the 1860s still loom large in the rearview mirror, but the civil rights movement of the 1950s and '60s is just a wee little speck on the horizon
