This blog was first posted on April 15, 2014. We rerun it today in honor of the anniversary of Abraham Lincoln's assassination on April 15th, 1865.

Invited to attend a TAH multiday seminar on the Cold War at the Ronald Reagan Presidential Library, social studies teacher Cade Lohrding was thrilled. At his rural Kansas school, he has few chances to discuss history with colleagues. He is also too young to have experienced the end of the Cold War, a time, he thinks, when American politics were less polarized than they are today.

For today’s blog, we are highlighting a document that helps students intersect two of the most historically important elements of the 1960s: the Civil Rights Movement and the Vietnam War.

One-Day seminars are the easiest way to engage with Teaching American History in person. These are free to attend for all social studies teachers and can be in historical locations, school districts, and educational service centers. For a few hours, teachers can dive into the content of primary source documents through a discussion with colleagues facilitated by a scholar. Lunch is provided, and at the end of the day you head home with an attendance letter.
