Rotary works on building world peace through a number of programs - including the Rotary Peace Centers.
Through academic training, practice, and global networking opportunities, the Rotary Peace Centers program develops leaders who become catalysts for peace and conflict prevention and resolution. These fellowships cover tuition and fees, room and board, round-trip transportation, and all internship and field-study expenses.

In just over a decade, the Rotary Peace Centers have trained more than 1,000 fellows for careers in peacebuilding. Many of them are serving as leaders at international organizations or have started their own foundations.
