I don't have any specific articles to link to today, but the month of April 1865 saw a lot of major events, such as the end of the Civil War, the fall of the Confederate States, and the assassination of Lincoln. Today marks the beginning of the 150th anniversary of a 30-day period that changed American history in more ways than virtually any other specific month ever has. (I even recall once seeing a show on the History Channel that focused entirely on the major events of April 1865.)
