In the 19th century unification movements there was a nice load of irredentism among their members which called for the creation of nation-states composed of the territories where nationals were living.
Sometimes opinions diverged and some people wanted to join with others to form a greater nation, while some wanted to stay apart and keep their existing rights.
I think Switzerland is an interesting case to speak of, as we know, this country is composed by people with different ethnic background: german, french and italian. Nut, If I recall correctly, Switzerland was kept untouched by the wars/nationalist movements ravaging her neighbours. However, I remember reading that in WWI there were clashed between the swiss who supported the side of thei ethnic background (french vs germans).
I want to know how big was the support among the swiss for unification with their cultural kin during the unification wars.
Also, how come that neither Sardinia/Italy nor Prussia/Germany tried to grab their respective language areas of Switzerland? Nobody could stop them from doing it, since France and Austria were badly beaten. I can guess France wouldn't mind much, since they could get their share through direct anexation or puppeting of the remaning french swiss cantons.
While thinking of this I can imagine Garibaldi infiltrating into Bellinzona area trying to spark an inside rebellion and then calling for Sardinia aid (like he done in Two Sicilies)
