History
The first official historical mention of Schliengen was in 820. It belonged formerly to the prince-bishopric of Basel. In 1796, Schliengen was the site of a battle between the French army commanded by Jean Victor Marie Moreau and the Coalition Army commanded by Archduke Charles of Austria. After the secularization which was a result of the German Mediatisation of 1803, Schliengen became a part of the Grand Duchy of Baden. The railway first reached Schliengen a 15 June 1847 when the track to Müllheim was completed. Schliengen was traditionally a part of the :de:Landkreis Müllheim|district of Müllheim, but has been part of the district of Lörrach since the :de:Gebietsreform#Kreisreform|district reform of 1973.
Religion
As a part of the prince-bishopric of Basel the Reformation passed Schliengen by. As a result, the area is still today mainly Roman Catholic. There are however Lutheran churches in Schliengen and each of its boroughs.

;Schloss Bürgeln The palace lies high over the vineyards of the Markgräflerland, between blooming cherry trees, fields, and woods. It was built in the 11th century as a church, and from 1100 as a monastery. In 1762 the palace was rebuilt by Provost Aloysius Mader and Abbot Meinrad Troger. The palace was threatened with closure in 1920, which was prevented through the formation of the Bürgeln-Bund. It is now privately owned, and is maintained and restored by donations and through the work of the Bürgeln-Bund. Around the palace is an 80m² rose garden, with views of the French Vosges mountains, Basel, and the Sausenburg ruins. Today, particularly in the summer, Schloss Bürgeln plays host to many events. These include conferences, seminars, concerts, and parties. In the middle 80's the palace was the filming location of a ZDF series entitled "Lorenz & Söhne", which followed the story of the Lorenz family and their winery. ; Wasserschloss Entenstein The Wasserschloss Entenstein, in the center of the town of Schliengen, is a small moated castle, which today houses the city hall and the district administration offices. The black and yellow striped shutters are a traditional symbol warning passers-by that the building has a moat. The surrounding castle park invites walkers in every season, and in the summer hosts several events, such as street and wine festivals. ; Gasthaus Krone in Mauchen In this inn one finds a delightful wall built of multicolored bottles.
