7. About 1432, "land under the jurisdiction of a town, state, etc.", probably from Latin territorium "land around a town, domain, district", from terra "earth, land".
An alternate theory, somewhat supported by the vowels of the original Latin word, suggests derivation from terrere "to frighten"; as in terrible; therefore, territorium would mean "a place from which people are warned off".
The meaning of "any tract of land, district, region" is first indicated in 1610. Specific U.S. sense of "organized self-governing region not yet a state" is from 1799. Territorial waters is traced back to 1841; territorial imperative "animal need to claim and defend territory" is recorded from 1966.
