Greatness is a concept of a state of exceptional superiority affecting a person or object in a particular place or area. Greatness can also be attributed to individuals who possess a natural ability to be better than all others. An example of an expression of the concept in a qualified sense would be "Hector is the definition of greatness" or "Napoleon was one of the greatest wartime leaders". In the unqualified sense it might be stated "George Washington achieved greatness within his own lifetime", thus implying that "greatness" is a definite and identifiable quality. Application of the terms "great" and "greatness" is dependent on the perspective and subjective judgements of those who apply them. Whereas in some cases the perceived greatness of a person, place or object might be agreed upon by many, this is not necessarily the case, and the perception of greatness may be both fiercely contested and highly idiosyncratic.
Historically, in Europe, rulers were sometimes given the attribute "the Great", as in Alexander the Great, Frederick the Great, Alfred the Great and Catherine the Great. Starting with the Roman consul and general Pompey, the Latin equivalent Magnus was also used, as in Pompeius Magnus, Albertus Magnus, and Carolus Magnus. The English language uses the Latin term magnum opus, (literally "great work") to describe certain works of art and literature.
