Christian Social Party (Austria) on 31 May 1922. From 1929 onwards, the party tried to form an alliance with the Heimwehr movement. Because of the instability of this coalition the party leadership decided to reform a coalition with the agrarian Landbund. In the process of establishing the so-called Austro-fascist dictatorship, Christian Social Chancellor Engelbert Dollfuß founded the Patriotic Front ("Vaterländische Front") on 20 May 1933, merging the CS with the Landbund, Heimwehr and other conservative groups. The party was finally dissolved with the entry into force of the "May Constitution" of 1934, the foundation of the Federal State of Austria. With the assumption of
Chancellor of Austria sovereign head of government was the State Chancellor of the Austrian Empire, a position only held by Klemens von Metternich. The office was later renamed to Minister-President of the Austrian Empire and remained from there on until the dissolution of Austria-Hungary. The first head of government after the monarchy was the State Chancellor of German-Austria, an office again only held by one person; Karl Renner. After allied powers declined a union between Austria and Germany, the office was renamed to just State Chancellor of Austria and later changed to Federal Chancellor, which remained the position's final form until present day.
