Andrew Cusack's always attractive and interesting blog brought to my attention this thoughtful article by John Zmirak on the Habsburgs and what replaced them. "Progress," indeed! In the past I've occasionally parted company with Mr. Zmirak in that he doesn't always seem to have much use for monarchies other than the Habsburgs', and is more willing than I am to accommodate himself to participation in the American political system, but when waxing lyrical on his favorite dynasty he is right on target.
Also worth reading (though endorsement of the site's other views is not implied) is "The Hands of the King" by Br. André Marie of the [New Hampshire] Saint Benedict Center.
