Poland–Lithuania

''Republic'' is still an alternative translation of the traditional name ''Rzeczpospolita'' of the Polish–Lithuanian Commonwealth.

The name was used officially for the Confederation, confederal union formed by Crown of the Kingdom of Poland, Poland and Grand Duchy of Lithuania, Lithuania 1569–1795. It is also often referred as "Golden Liberty, Nobles' Commonwealth" (1505–1795, i.e., before the union). In the contemporary political doctrine of the Polish–Lithuanian Commonwealth, "our state is a Republic (or Commonwealth) under the presidency of the King". The Commonwealth introduced a doctrine of religious tolerance called Warsaw Confederation, had its own parliament ''Sejm'' (although elections were restricted to nobility and elected kings, who were bound to certain contracts ''Pacta conventa (Poland), Pacta conventa'' from the beginning of the reign). "A commonwealth of good counsaile" was the title of the 1607 English translation of the work of Wawrzyniec Grzymała Goślicki "De optimo senatore" that presented to English readers many of the ideas present in the political system of the Polish–Lithuanian Commonwealth.

Current use

Australia

"Commonwealth" was first proposed as a term for a Federation of Australia, federation of the six Australian crown colony, crown colonies at the Constitutional Convention (Australia)#1891 convention, 1891 constitutional convention in Sydney. Its adoption was initially controversial, as it was associated by some with the republicanism of

(#England, see above), but it was retained in all subsequent drafts of the constitution. The term was finally incorporated into law in the ''Commonwealth of Australia Constitution Act 1900'', which established the federation. Australia operates under a federal system, in which power is divided between the federal (national) government and the States and territories of Australia, state governments (the successors of the six colonies). So, in an Australian context, the term "Commonwealth" (capitalised), which is often abbreviated to Cth, refers to the Government of Australia, federal government, and "Commonwealth of Australia" is the official name of the country.
