When did it become normal for men to wear wedding rings?

The story I've always heard is that it was the two world wars that really raised how commonly men wore wedding rings. Men going off to war where they knew they may very well die wanted a marker of their wife. And because of what a high percentage of the population fought in those two wars it then became commonplace. Maybe apocryphal I don't know. But certainly from what I've read it's early to mid c.20th that it took off. I'd wager changing attitudes to women must be a factor too. Women wore rings because their relationship status, the fact they were wedded to a man, was traditionally seen as perhaps the most important thing about them. Not the case with men, so there was no need for them to wear a marker of their relationship status. But as times changed and marriage became to be seen less as women being kept by a man and more as a partnership, only the woman wearing the ring perhaps started to seem a bit antiquated.
