If there is one thing many people can relate to, it's the experience of going to school. School is a critical time for kids and young adults. Kids start going to school when they are young, and they don't leave until they are at least 17 or 18, even older if they choose to go to university or college. School isn't only for becoming book-smart, but it also teaches kids fundamental socialization skills and hands-on skills, too. It's cool to go to school.

Throughout the years, going to school has changed a lot. Technology is prevalent in schools these days. Kids have phones and computers to type on now, and a lot of work is done online. One thing that is the same, though, is the event of graduation. It all leads up to one hopeful day when students walk across a stage to begin the next chapter.

Here, we have collected 25 images from graduation days and classes in the past. Enjoy this nostalgic journey and observe some people's proudest days in history.
