A referendum on whether the Provisional Provincial Assembly of Vorarlberg should announce the intention of the people of Vorarlberg to join the Swiss Confederation and to enter into negotiations with the Swiss Federal Government was held on 11 May 1919. The proposal received substantial support, with 80.7% of voters and a majority in 93 out of 96 municipalities voting in favor.

Opinions on the integration of Vorarlberg, a predominantly Catholic and rural region with a concentrated industrial sector, into the Swiss Confederation were mixed. A petition for a popular initiative for union failed and only one member of the seven-person Swiss Federal Council, Foreign Affairs Minister Felix Calonder, strongly endorsed the idea. The Swiss government did, however, provide aid to the region, allowing the local government to avoid a serious famine.

The Treaty of Saint-Germain-en-Laye, signed on 10 September 1919, made no provision for a plebiscite in Vorarlberg and with no support from any outside power, the province was to remain with Austria as the independence of Austria was "inalienable otherwise than with the consent of the Council of the League of Nations."
