Global African American History Timelines:
Absorbing and referring to a time line (or better, yet, making your own) is an effective way of learning the sequential course of events and often the timeline can reveal the possibility of the relationship between causes, people and events that occurred in the same time period, while not in the same geographical area.
This is particularly true in surveying a discreet subject, which exists in relationship to many other events and background. African American studies is such a subject.
