Question: What major landmarks are in the district Rohrbach went to in 1803? Passage:Rohrbach was first mentioned in 795 as Roorbah when a local noble, Heribold, gave his lands in Madiswil to the church in Rohrbach. In the 9th century some land around the village was given to the Abbey of St. Gall. The Abbey established an administrator in Rohrbach to manage their lands in the Oberaargau region. Since the Abbey was an Imperial Abbey, the administrator and the landholders on the Abbey's land had immunity from the local count's court and could only be arrested or tried by the Abbey court. At the beginning of the 14th century the bailiwick and the low court of the local Barons of Ruti. Between 1314 and 1370 both offices were held by the Count of Signau and after 1371 by the Count of Grunenberg. The Grunenberg Counts incorporated the village into their personal territory. Hermann of Eptingen then acquired the rule over the village by marriage. He supported the Austrian Habsburgs in the Old Zurich War (144046) and lost the village to a Bernese army. After the war, the village was returned to his wife in 1449. In 1504 Bern bought the entire village from Hermann's decedents. In 1505 the village was incorporated into the bailiwick of Wangen. However, Rohrbach retained several special privileges. They were exempt from forced labor for the bailiff and in wars they marched under the banner of the city of Bern. After the 1798 French invasion it was part of the District of Langenthal in the Helvetic Republic and in 1803 it went to the District of Aarwangen.

Question: How long had the European Union been established when Albania was granted membership to NATO? Passage:In 1991, the Socialist Party of Albania, with specific social democratic ideology took control of the country through democratic elections. One year later the Democratic Party of Albania won the new elections. After 1990, Albania has been seeking a closer relationship with the West. What followed were deliberate programs of economic and democratic reform, but Albanian inexperience with capitalism led to the proliferation of pyramid schemes which were not banned due to the corruption of the government. Chaos in late 1996 to early 1997, as a result of the collapse of these pyramid schemes, alarmed the world and prompted the influx of international peacekeeping forces. In 1995, Albania was accepted into the Council of Europe and requested membership in NATO (obtained in 2009) and is a potential candidate country for accession to the European Union. The workforce of Albania has continued to emigrate to Western countries, especially Greece and Italy.
