I have been going through our more than 300 topics, looking for the ones you might be able to use in your lessons. I can't possibly list all the helpful ones here, but this will give you some ideas. If you don't see your favorite topic, consider writing it yourself-we always need new editors, and while some of us have extensive writing credit and credentials, others of us are just everyday people writing about what we love. This topic tells you what holidays or anniversaries are coming up. Use them to plan interesting thematic units, and mark them on your calendar for next year.
Special events are world-wide.
American Civil War Mike is my managing editor, and a good one he is. He has excellent articles on the war, so be sure to turn to him for the extended information your textbook doesn't have. His links to other Civil War sites are excellent. Be sure to check out his article on the Emancipation Proclamation. Ancient Egypt I've linked Nikole's topic on my page already, but it is worth a second mention.
