The Teen Titans (also known as Titans) was a group of young superheroes that work together with the Justice League and all other superhero teams to fight crime and protect the innocent.
The team was all but destroyed by Darkseid's forces.
This is going off the debut of comic book characters. In the cases of characters who were introduced in other media originally and added to the comics canon later along (ex: Harley Quinn) it'll go by actual debut year.
