What is a knighthood in the UK?
A knighthood is an honor given by the British monarch to people who have made a major contribution to their field or to society. Men receive the title Sir, and women receive the equivalent honor of damehood, with the title Dame.
Knighthoods are usually awarded in the New Year Honours and the King's Birthday Honours. Recipients are nominated by the government or the public and approved by the monarch.
Knights are often appointed as Knight Bachelor or as members of orders such as the Order of the British Empire.
The ceremony
In an investiture ceremony, the recipient kneels, and the monarch or another royal touches them on each shoulder with a sword. This is called dubbing.
Famous knights and dames include Sir Paul McCartney, Sir David Attenborough, Dame Judi Dench and Sir Elton John.
Citizens of other countries can receive honorary knighthoods but cannot use the title Sir or Dame.
Knighthoods can be taken away, a process known as forfeiture, in cases of serious misconduct.
Honours lists are published twice a year, and recipients often include people who have worked quietly in their communities as well as famous figures.
