In a war, the Roman empire was beginning to conscript its men to be sent out to fight. In the midst of all the trouble, soldiers still hoped to marry their special someone, though it was banned. They couldn’t marry - the emperor thought that having a family would make men less likely to want to go to war.

But there was one priest, named St Valentine, who still married couples together because he believed in love. The emporer had found out, and the day that St Valentine’s was beheaded is what we call Valentine’s day - February 14th. The whole idea that love goes through everything - even war - became great, and that’s what Valentine’s day is really about: it celebrates it!

(Though chocolate factories and factories that make love heart shaped products have eventually taken over the holiday, but anyway)
