The internet loves a made up holiday, and #NationalSelfieDay certainly delivers. From celebrity posts to creative Twitter users, everyone seems to be looking for that viral validation that's so important in 2019. But selfies aren't just for people with a front-facing camera on their phone, people have been taking pictures of themselves since the 1800s. Here are some of the best currently trending on this most trendy "holiday."

What's a selfie? Merriam-Webster defines a selfie as, "A photograph that one has taken of oneself, typically one taken with a smartphone or webcam and shared via social media." Even though modern technology is technically part of what makes a selfie a selfie, the person credited as the father of the selfie is Robert Cornelius, who took the first selfie in 1839.

Happy #NationalSelfieDay
This is probably the first portrait of a human and the first selfie. A daguerreotype by Robert Cornelius taken in late 1839. He wrote on the back, "The first light picture ever taken. 1839." pic.twitter.com/D0k7vXwFaB

Cornelius, a photographer from Philadelphia, took the selfie in his family's backyard using a method of early photography called daguerrotypy—a large box camera capturing the light through a pair of opera glasses. Typically it would take three to 15 minutes for the light to capture the picture, so Cornelius more than likely stood there for a hot second waiting for the camera to capture the image (imagine Kim Kardashian having to wait that long for a selfie).

Of course, a lot has changed since that first selfie. Now there's a museum dedicated to them and Oxford Dictionary even declared "selfie" the word of the year in 2013.

This year, celebrities, presidential candidates, TV shows and an astronaut got in on the #NationalSeflieDay game. Here are some of the best.
