League \League\, n. [F. ligue, LL. liga, fr. L. ligare to bind;
   cf. Sp. liga. Cf. {Ally} a confederate, {Ligature}.]
   An alliance or combination of two or more nations, parties,
   or persons, for the accomplishment of a purpose which
   requires a continued course of action, as for mutual defense,
   or for furtherance of commercial, religious, or political
   interests, etc.

         And let there be 'Twixt us and them no league, nor
         amity.                                   --Denham.

   Note: A league may be offensive or defensive, or both;
         offensive, when the parties agree to unite in attacking
         a common enemy; defensive, when they agree to a mutual
         defense of each other against an enemy.
