Princeton alumni have returned to campus to celebrate Commencement festivities and reunite with friends since the earliest days of the institution in the 1700s, when it was still known as The College of New Jersey. Beginning as informal gatherings of alumni, faculty and guest speakers, a milestone was reached at Princeton's 100th Commencement in 1847 that drew 700 graduates. Today, more than 20,000 alumni, family and friends participate in this annual gathering, known as Reunions. This year, the campus will be awash with Princetonians past and present Thursday through Sunday, May 26-29.

The marching of the classes across campus, by which alumni processed to class dinners and the traditional Yale baseball game, quickly grew into the modern P-rade, complete with costumes, banners and hired bands, which is a distinctive and colorful highlight of Reunions.
