British Private Schools:
Fagging was a traditional practice in British public schools and also at many other boarding schools, whereby younger pupils were required to act as personal servants to the eldest boys.[1][2][3] Although probably originating earlier, the first accounts of fagging appeared in the late 17th century.[4]: 23 Fagging sometimes involved physical abuse[4]: 23–25 and/or sexual abuse.[5] Although lessening in severity over the centuries, the practice continued in some institutions until the end of the 20th century.[4]: 23–25
