Europe (i/ˈjʊərəp/EWR-əp or /ˈjɜrəp/YUR-əp) is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally divided from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting the Black and Aegean Seas.
Graubünden or Grisons (German: Graubünden, [ɡraʊˈbʏndən] ( listen); Italian: Grigioni[ɡriˈdʒoːni]; Romansh: Grischun[ɡʁiˈʒun] ( listen); see also other names) is the largest and easternmost canton of Switzerland. The canton shares borders with the cantons of Ticino, Uri, Glarus and St. Gallen and international borders with Italy, Austria and Liechtenstein. The name Graubünden translates as the "Grey Leagues," referring to the canton's origin in three local alliances, the League of God's House, the Grey League, and the League of Ten Jurisdictions. Graubünden is also home to three of Switzerland's ethnic groups and the subsequent languages of Swiss German, Italian and Romansh are all native to the state. It is also the only canton where the Romansh language is still spoken.
