Today is the one hundred and fiftieth anniversary of the inauguration of Abraham Lincoln. The New York Times has been running a fabulous series on the Opinion page (and apparently on Facebook as well) tracing the rise of the Civil War by a number of historians, each addressing different, and often, unusual, themes. I heartily recommend it for the history lovers among you. It's fascinating, utterly riveting, and is called Disunion.
And heartening to see that we've survived far worse threats to our union.
