EVERLASTING LEAGUE, a league formed in Switzer land on Aug. 1, 1291 between Uri, Schwyz and Nidwalden for the purpose of self-defence. After the defeat of Austria at the battle of Mortgarten representatives of the victorious confederates met at Brunner on Dec. 9, 1315 and a renewed treaty was drawn up, the second document being largely an expansion of the first, with the addition of certain important clauses stipulating that no government was to be recognized or negotiations made except with the consent of the three districts constituting the League.
