Six of the 26 cantons are traditionally, but no longer officially, called "half-cantons" (, , , ). In two instances (Basel and Appenzell) this was a consequence of a historic division, whilst in the case of Unterwalden a historic mutual association, resulting in three pairs of half-cantons. The other 20 cantons were, and in some instances still are—though only in a context where it is needed to distinguish them from any half-cantons—typically termed "full" cantons in English. The first article of the 1848 and 1874 constitutions constituted the Confederation as the union of "twenty-two sovereign cantons", referring to the half-cantons as "
Unterwalden ( ['
above and
beneath the woods'])", "Basel ( ['city and country'])" and "Appenzell ( ['both Rhoden'])". The 1874 constitution was amended to list 23 cantons with the accession of the
Canton of Jura in 1978. The historic half-cantons, and their pairings, are still recognizable in the first article of the
Swiss Federal Constitution of 1999 by being joined to their other "half" with the conjunction "and": The 1999 constitutional revision retained the traditional distinction, on the request of the six cantonal governments, as a way to mark the historic association of the half-cantons to each other. While the older constitutions referred to these states as "half-cantons", a term that remains in popular use, the 1999 revision and official terminology since then use the appellation "cantons with half of a cantonal vote". The
, 1 and 2 francs coins as minted since 1874 represent the number of cantons by 22 stars surrounding the figure of
Helvetia on the obverse. The design of the coins was altered to show 23 stars, including Jura, beginning with the 1983 batch. The design has remained unchanged since, and does not reflect the official number of "26 cantons" introduced in 1999. , 1833 The reasons for the existence of the three pairs of half-cantons are varied: •
Unterwalden never consisted of a single unified jurisdiction. Originally, Obwalden, Nidwalden, and the
Abbey of Engelberg formed distinct communities. The collective term
Unterwalden remains in use, however, for the area that partook in the creation of the original Swiss confederation in 1291 with
Uri and
Schwyz. The
Federal Charter of 1291 called for representatives from each of the three "areas". • The historical
canton of Appenzell divided itself into "inner" and "outer" halves as a consequence of the
Reformation in Switzerland in 1597:
Appenzell Innerrhoden (
Catholic) and
Appenzell Ausserrhoden (
Protestant). • The historical
canton of Basel was divided in 1833 after the Basel countryside (which became the canton of
Basel-Landschaft) declared its independence from the city of Basel (which became the
canton of Basel-Stadt), following a period of protest and armed conflict about the under-representation of the more populous countryside in the canton's political system. With their original circumstances of partition now a historical matter, the half-cantons are since 1848 equal to the other cantons in all but two respects: • They elect only one member of the
Council of States instead of two (Cst. art. 150 par. 2). This means there are a total of 46 seats in the council. • In
popular referendums about constitutional amendments, which require for adoption a national popular majority as well as the assent of a majority of the cantons (
/ ), the result of the half-cantons' popular vote counts only one half of that of the other cantons (Cst. arts. 140, 142). This means that for purposes of a constitutional referendum, at least 12 out of a total of 23 cantonal popular votes must support the amendment. Between 1831 and 1833 the canton of Schwyz was divided into half-cantons: (Inner) Schwyz and the break-away
Outer Schwyz; in this instance, the half-cantons were forced by the Confederation to settle their disputes and reunite. In the 20th century, some
Jura separatists suggested a new canton of Jura to be divided into half-cantons of North Jura and South Jura. Instead, North Jura became the (full)
canton of Jura while South Jura remains in the canton of Bern as the
region of
Bernese Jura. == Names in national languages ==
