ALLEGIANCE. The tie which binds the citizen to the government, in return for the protection which the government affords him.

2. It is natural, acquired, or local. Natural allegiance is such as is due from all men born within the United States; acquired allegiance is that which is due by a naturalized citizen. It has never been decided whether a citizen can, by expatriation, divest himself absolutely of that character. 2 Cranch, 64; 1 Peters' C. C. Rep. 159; 7 Wheat. R. 283; 9 Mass. R. 461. Infants cannot assume allegiance, (4 Bin. 49) although they enlist in the army of the United States. 5 Bin. 429.

3. It seems, however, that he cannot renounce his allegiance to the United States without the permission of the government, to be declared by law. But for commercial purposes he may acquire the rights of a citizen of another country, and the place of his domicil determines the character of a party as to trade. 1 Kent, Com. 71; Com. Rep. 677; 2 Kent, Com. 42.

4. Local allegiance is that which is due from an alien, while resident in the United States, for the protection which the government affords him. 1 Bl. Com. 366, 372; Com. Dig. h.t; Dane's Ab. Index, h. t.; 1 East, P.C. 49 to 57.

ALLIANCE, relationship. The union or connexion of two persons or families by marraiage, which is also called affinity. This is derived from the Latin preposition ad and ligare, to bind. Vide Inst 1, 10, 6; Dig 38, 10, 4, 3; and Affinity.

ALLIANCE, international law. A contract, treaty, or league between two sovereigns or states, made to insure their safety and common defence.

2. Alliances made for warlike purposes are divided in general into defensive and offensive; in the former the nation only engages to defend her ally in case he be attacked; in the latter she unites with him for the purpose of making an attack, or jointly waging the war against another nation. Some alliances are both offensive and defensive; and there seldom is an offensive alliance which is not also defensive. Vattel, B. 3, c. 6, 79; 2 Dall. 15.

ALLISION, maritime law. The running of one vessel against another. It is distiguished from collision in this, that the latter means the running of two vessels against each other; this latter term is frequently used for allision.
