Five Kingdom Classification System
Definition and Associated Terms
When Carl Linnaeus introduced the rank-based system of nomenclature into biology, the highest rank was given the name "kingdom" and was followed by four other main or principal ranks: the class, order, and genus. Later two further main ranks were introduced, making the sequence kingdom, phylum or division, class, order, family, genus and species. In the 1960s a rank was introduced above kingdom, namelydomain (or empire), so that kingdom is no longer the highest rank.
Prefixes can be added so subkingdom and infrakingdom are the two ranks immediately below kingdom. Superkingdom may be considered as an equivalent of domain or empire or as an independent rank between kingdom and domain or subdomain. In some classification systems the additional rank branch (Latin: ramus) can be inserted between subkingdom and infrakingdom (e.g. Protostomia and Dueterstomia in the classification of Cavalier-Smith). Because of its position, branch can be considered as a minor rank of the kingdom group even if it is not etymologically derived from it.
Systems of classification
Historical development
The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals, while his pupilTheophrastus (c. 371–c. 287 BC) wrote a parallel
