The enlargement of Switzerland by way of the admission of new cantons to the Swiss Confederation ended in 1815. After a failed attempt of Vorarlberg to join Switzerland in 1919, the idea of resuming Swiss enlargement was revived in 2010 by a parliamentary motion of 28 right-wing members of the Swiss federal parliament. Their proposal would change Swiss law to allow French, German, Austrian or Italian border regions to join the Confederation, should the majority of the population in these regions request this. As possible candidates for accession, the motion names Alsace (F), Aosta (I), South Tyrol (I), Jura (F), Vorarlberg (A), Ain (F), Savoie (F), Baden-Württemberg (D), Varese (I), Como (I) "and others".
