Liechtenstein is formed of two historic regions, the Oberland (six independent municipalities) and the Unterland (five municipalities). These regions serve as constituencies during the parliamentary elections. Today there is nothing to indicate that modern-day Liechtenstein once used to be two separate regions.
Sometimes the populations of Liechtenstein's two historic regions, the Dominion of Schellenberg and the County of Vaduz, still like to tease each other. While those living in the Unterland (formerly the Dominion of Schellenberg) are known for their conservative voting habits, the citizens in the Oberland (formerly the County of Vaduz) have always been considered more open to new ideas.
If you take a look at a map of Liechtenstein then you will quickly see that the Unterland has much more land on the valley floor suitable for development than the Oberland. Differences between the two regions are also reflected in marriage trends. Those living in the Unterland traditionally married spouses from the border region in nearby Austria or in the Catholic municipalities in the Swiss canton of St. Gallen. People living in the Oberland, surrounded by Protestant areas to the west and south, tended to marry within their own communities. Today, however, this geographical division is hardly worth mentioning. The only manifestation is to be found in the political system, with the Oberland entitled to 15 members of parliament and the Unterland 10.
