to Blieskastel and built up Blieskastel as their seat. Under the regent Marianne von der Leyen a cultural center was established in Blieskastel. A period of brisk building activity followed. The palace was further expanded and on the Schlossberg there were a number of outstanding palaces and mansions for the court officials of the small court, including the so-called "Schlößchen", attributed to the Zweibrücken building director and architect Christian Ludwig Hautt. In addition, other master builders worked there, such as A. G. F. Guillemard, Matthias Weysser, Peter Reheis and the master carpenter Franz Schmitt. During this time the former Franciscan monastery church, the former orphanage and the government building were built. With the French Revolution, the von der Leyen were expelled in 1793, their palace plundered and subsequently destroyed. The ruins were removed in 1802. In 1795 Blieskastel, like the entire left bank of the Rhine, came under French rule, and in 1798 was the capital of the canton of Blieskastel in the Sarre Department. With the defeat of France in 1814, the area belonging to France west of the Rhine came first to the Generalgouvernement Mittelrhein. The canton of Blieskastel was placed under the joint Austro-Bavarian State Administration Commission after 1814. In 1816 Austria and Bavaria concluded an exchange agreement, after which the Rheinkreis, the later Bavarian Palatinate, was assigned to kingdom of Bavaria. The canton of Blieskastel was subordinated to the district administration in Zweibrücken, and, in 1818, came to the Landkommissariat Zweibrücken, and in 1902 to the newly formed district office Sankt Ingbert. From 1920 to 1935 Blieskastel belonged to the Territory of the Saar Basin (Saargebeit), which was put under French administration by a mandate of the League of Nations for 15 years. In the Nazi era Blieskastel was governed from Saarbrücken, until 1935 as part of Pfalz-Saar, until 1940 as part of the Saarpfalz and until the end of the war together with Lorraine as "Westmark". After the Second World War, the city of Blieskastel was initially in the French occupation zone and from 1947 to 1956 in the partly autonomous Saarland, which, after rejection of the second Saar statute on January 1, 1957, became a federal state of the Federal Republic of Germany. As part of a territorial and administrative reform of 1974, Blieskastel, which until then belonged to the district of Sankt Ingbert, became part of the newly created Saar-Pfalz-Kreis (now Saarpfalz-Kreis).
