No. They just showed up about a hundred years ago and started eating everybody they could find. After a while, people built three walls to keep them out and that worked for a while until one Titan bigger than the rest kicked a hole in it and let a bunch of them inside. So everybody moved into the next wall which meant not a lot of space or food. It's... really bad. There's only one way to kill them and that's why we in the military are trained to do so. But even we can get eaten by a Titan. A lot of my friends did.
