The Neue Helvetische Gesellschaft (NHG) / "New Helvetic Society") was a non-party political movement in Switzerland, founded in 1914 and subsumed into a successor organisation in 2007.
In 1912 the three (by origin francophone) writers Robert de Traz, Alexis François and Gonzague de Reynold produced a manifesto entitled "Pro helvetica dignitate ac securitate" ("For Swiss dignity and Security”) in which they called for the creation of such a society.
In 1914 it acquired nationwide exposure as a result of a speech given by the high-profile poet Carl Spitteler and entitled "Unser Schweizer Standpunkt" (literally "Our Swiss Standpoint").
Following the First World War (from which Switzerland abstained) the NHG launched a successful campaign for the country to enter the League of Nations.
Later, in 1952, it campaigned energetically and effectively to block the creation of a massive hydro-electric power station at the Rhine Falls near Schaffhausen.
