Paper instructions:
Discuss one question, person, group, event, theme, or other topic concerning world history since 1500 or so, in light of at least three (3) different primary sources and at least two (2) secondary sources. One of the primary source choices can be from the sources we discussed during the term and the others can be ones assigned and not discussed, or ones researched and found by you as a young historian. The secondary sources can also be from our course, or from your own library research.
