Actions are another source base historians use to determine meaning. What actions mean in the greater societal, or personal struggle gives greater understanding oh how that greater societal structure affected the individual. Kali Gross utilizes this method in her book Colored Amazons. She interprets the meaning behind what black female crime in 19th-century Philadelphia meant in the greater context of black female womanhood. She does so with court documents and newspaper articles concerning these female criminals. Of course, these documents are biased, but Kali contends with that. The fact is what these women did and the language society expressed those crimes through have deep meaning: why specific words were chosen over others and such.
