A good example comes during Miss Gates' lesson on Adolph Hitler and his treatment of the Jews in Germany. This takes in 1935 (we know this since Atticus states in his summation to the jury that it is "in this year of grace, 1935..."), and Hitler's anti-Semitic persecution was in its early stages.
Other examples of historical allusions include:
- References to the Great Depression and the stock market crash of 1829.
- References to Franklin Delano Roosevelt (and his wife, Eleanor) and the various New Deal programs such as the WPA.
- References to the Civil War (Appomattox) and several Confederate generals (Stonewall Jackson, Joe Wheeler, John Bell Hood).
- Dill's viewing of the film Dracula (1931).
- Scout's joking mention of Bullfinch, as in Bullfinch's Mythology.
For an excellent listing of historical allusions in TKAM, check out the link below:
1929, The wall street crash induces the Great Economic Depression. The novel is set during this time. Maycombians are poor because of this.
1931, The Scottsboro Trials - Similiar outcome to the trial in the novel.
1954, The Civil Rights movement. - Slave trade (Calpurnia).
Atticus tells Jem the Ku Klux Klan will "never come back".
The history of the Finch family is typical of the South in the 30's. They make thier living by selling cotton.
Hope this helps.
