A province is almost always an administrative division, within a country or state. The term derives from the ancient Roman provincia, which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term province has since been adopted by many countries, and in those with no actual provinces, it has come to mean "outside the capital city". While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of federal authority, especially in Canada. In other countries, like China, provinces are the creation of central government, with very little autonomy.
The English word "province" is attested since about 1330 and derives from the 13th-century Old French "province", which itself comes from the Latin word "provincia", which referred to the sphere of authority of a magistrate; in particular, to a foreign territory.
A popular etymology is from Latin"pro-" ("on behalf of") and "vincere" ("to triumph" or "to take control of"). Thus a "province" would be a territory or function that a Roman magistrate held control of on behalf of his government. In fact, the word Province is an ancient term from public law, which means: "office belonging to a magistrate". This agrees with the Latin term's earlier usage as a generic term for a jurisdiction under Roman law.
In France, the expression "en province" still tends to mean "outside the Paris region." Equivalent expressions are used in Peru ("en provincias", "outside the city of Lima"), Mexico ("la provincia", "lands outside Mexico City"), Romania ("în provincie", "outside the Bucharest region"), Poland ("prowincjonalny", "provincial"), Bulgaria ("в провинцията", "v provintsiyata", "in the provinces"; "провинциален", "provintsialen", "provincial") and the Philippines (taga-probinsiya, "from outside Metro Manila", sa probinsiya, "in the provinces"). Similarly, in Australia "provincial" refers to parts of a state outside of the state capital.
