The twin towns of LAUFEN/OBERNDORF Laufen owes its former economical and cultural significance to the river Salzach,which forms a peninsula with its sharp curves（弯） there. Laufen’s economic boom began with the salt trade and the shipping on the river.The salt—mainly coming from Hallein and Bad Reichenhall—was loaded onto bigger ships downstream,which made Laufen one of the most important ports of shipment for salt in Salzburg and Bavaria. The archbishop（大教主） of Salzburg had given special privileges to the people who were involved in the shipping of salt on the river Salzach. The Napoleonic Wars brought occupation and serious distces.They brought the sudden end to the independent state of the Duke—Archbishop of Salzburg.The end of the 18th century brought a decrease in shipping because of the general economic situation.On the 1st May 1816 Salzburg definitively became a part of Austria （Munich agreement） that’s why the Salzach became the border between Bavaria and Austria.Laufen’s suburbs Oberndorf and Altach were divided up.The number of inhabitants fell from 1392 to 809.Even the re－unification of the two towns’shipsmen’s guilds（行会） and the reorganization of 1928 could not pr the decline of shipping which finally came to an end in the late 19th century. 小题1:________played an important role in Laufen’s economy and culture life.
