Pinning ceremony (nursing)
A pinning ceremony is a symbolic welcoming of newly graduated or soon-to-be graduated nurses into the nursing profession. The history of the ceremony dates back to the Crusades in the 12th century, and later, when Queen Victoria awarded Florence Nightingale the Royal Red Cross for her service as a military nurse during the Crimean War.
