To make a citizen. The first quotation goes back to T. Pickering, ab. 1811. (N.E.D.)
1841. To citizenize is to make a citizen, to admit to the rights and privileges of a citizen; and [Webster] gives as an example, that “Talleyrand was citizenized in Pennsylvania, when there in the form of an emigrant.”—Mr. Young of Ill., U.S. Senate, Feb. 1: Cong. Globe, p. 103, App.
1843. No man can be citizenized in this corner of the world.—Blackwood’s Mag., liv. 325/2 (Sept.). (N.E.D.)
1850. An act of Congress [was] as necessary to citizenize the one as the other.—Mr. Savage of Tenn., House of Repr., May 13: Cong. Globe, p. 559, App.
1850. [If Massachusetts should] see fit to citizenize monkeys, it will furnish no reason why we should allow them such rights in the streets of Charleston.—Mr. McQueen of S. Carolina, the same: Id., p. 738, App.
