A commonwealth is a traditional English term for a political community founded for the common good. Historically, it has been synonymous with " republic". The noun "commonwealth", meaning "public welfare, general good or advantage", dates from the 15th century. Originally a phrase (the common-wealth or the common wealth – echoed in the modern synonym "public wealth"), it comes from the old meaning of "wealth", which is "well-being", and is itself a loose translation of the Latin res publica (republic). The term literally meant "common well-being". In the 17th century, the definition of "commonwealth" expanded from its original sense of "public welfare" or "commonweal" to mean "a state in which the supreme power is vested in the people; a republic or democratic state".

The term evolved to become a title to a number of political entities. Three countries – Australia, the Bahamas, and Dominica – have the official title "Commonwealth", as do four U.S. states and two U.S. territories. Since the early 20th century, the term has been used to name some fraternal associations of states, most notably the Commonwealth of Nations, an organisation primarily of former territories of the British Empire. The organisation is not to be confused with the realms of the Commonwealth.

Historical use

Rome

Translations of Ancient Roman writers' works to English have on occasion translated "'' Res publica''", and variants thereof, to "the commonwealth", a term referring to the Roman state as a whole.

England

The Commonwealth of England was the official name of the political unit (''de facto'' military rule in the name of parliamentary supremacy) that replaced the Kingdom of England (after the English Civil War) from 1649–53 and 1659–60, under the rule of Oliver Cromwell and his son and successor Richard. From 1653 to 1659, although still legally known as a Commonwealth, the republic, united with the former Kingdom of Scotland, operated under different institutions (at times as a ''de facto'' monarchy) and is known by historians as the Protectorate. In a British context, it is sometimes referred to as the "Old Commonwealth".

Iceland

The Icelandic Commonwealth or the Icelandic Free State ( is, Þjóðveldið) was the state existing in Iceland between the establishment of the Althing in 930 and the pledge of fealty to the Norwegian king in 1262. It was initially established by a public consisting largely of recent immigrants from Norway who had fled the unification of that country under King Harald Fairhair.

Philippines

The Commonwealth of the Philippines was the administrative body that governed the Philippines from 1935 to 1946, aside from a period of exile in the Second World War from 1942 to 1945 when Japan occupied the country. It replaced the Insular Government, a United States territorial government, and was established by the Tydings–McDuffie Act. The Commonwealth was designed as a transitional administration in preparation for the country's full achievement of independence, which was achieved in 1946. The Commonwealth of the Philippines was a founding member of the United Nations.

Poland–Lithuania

''Republic'' is still an alternative translation of the traditional name ''Rzeczpospolita'' of the Polish–Lithuanian Commonwealth. Wincenty Kadłubek (Vincent Kadlubo, 1160–1223) used for the first time the original Latin term ''
