The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. 

Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they created their own honours.

Current classes

The five classes of appointment to the Order are, from highest grade to lowest grade:

1. Knight Grand Cross or Dame Grand Cross of the Most Excellent Order of the British Empire (GBE)
2. Knight Commander or Dame Commander of the Most Excellent Order of the British Empire (KBE or DBE)
3. Commander of the Most Excellent Order of the British Empire (CBE)
4. Officer of the Most Excellent Order of the British Empire (OBE)
5. Member of the Most Excellent Order of the British Empire (MBE)
