I'm getting married on Saturday, and I was reflecting on the history of marriage for my speech. In the olden days, marriage was a way to make peace between nations for royals, and to marry into prosperity for the common people. But after years of these political schemes, it has started to be about love, which is discussed in this excellent question: When and why did marriage become about love?
But I'd like to know whether marriage ever ended a war, or stopped a war from starting? Examples would be great!
