Valentine’s Day has gone and passed, but that doesn’t mean we can’t have a history lesson on it.

It started as a feast to honor saints and to celebrate romance. In the 18th century, it became less of a feast to celebrate saints and more of a day to give the people you loved chocolates, roses, and heart-shaped cards.

In the 19th century, hand-written cards were largely replaced with mass produced Valentine’s cards from companies. People also started giving keys to their valentine to show that they “unlocked their heart,” and they were also given to children to ward off epilepsy. The Orthodox and Lutheran are often the most to celebrate it.

The 1800s was when most companies started selling what we use today to celebrate: boxes of chocolates, roses, and cards with Cupids.

Around 190 million cards are sent in the United States, and that doesn’t include the millions that children in schools hand out to their classmates. It is a HUGE source for money in the country.

There’s also many movies and cartoons based around Valentine’s Day. The TV show Parks and Rec also made their own “Galentine’s Day,” which is a day to celebrate your female friends.

Valentine’s Day isn’t just a day for romance, it’s also meant to celebrate anyone you deem important in your life.
