Karl Josef Seitz (German pronunciation: [kaʁl ˈzaɪts] ^ⓘ; 4 September 1869 – 3 February 1950) was an Austrian politician of the Social Democratic Workers' Party. He served as member of the Imperial Council, President of the National Council and Mayor of Vienna.^[1]

Seitz was born in Vienna, the capital of Austria-Hungary. He was the son of a struggling small-time coal trader. After the premature death of his father, in 1875, the family was thrown into abject poverty, and Seitz had to be sent off to an orphanage.

He, nonetheless, received adequate education and earned a scholarship so that he could enroll in a teacher-training college in the city of St. Pölten, Lower Austria. In 1888, he took employment as a public elementary school teacher in Vienna.

Already an outspoken social democrat, he was disciplined several times for his political activism. His founding of a Social Democratic teachers' union in 1896 led to his delegation into the Lower Austrian Board of Education in 1897, which then led to his termination as a teacher later that year.

Seitz now turned to full-time politics and established himself as one of the party's most eminent experts on educational policy. In 1901, Seitz was elected to the Imperial Council and, in 1902, to the provincial parliament of Lower Austria. Following the outbreak of World War I in 1914, Seitz developed pronounced pacifist leanings and participated in the 1917 Stockholm Socialists' Congress.

Seitz entered history in 1918, when Austria-Hungary was breaking down, and its disintegration into smaller independent nation states was becoming manifest. On 21 October the Imperial Council members, representing the empire's ethnically-German provinces, moved to form a Provisional National Assembly for "German Austria". In its constituent session, the Provisional National Assembly appointed Seitz as one of its three chairmen. All three presidents together functioned as head of state in the Staatsratsdirektorium. After the election to the Constituent National Assembly, that was changed on 15 March 1919. Seitz became the First President, and the other two presidents became deputies of the First President. The First President was also to be head of state. He retained the position until 9 December 1920.

Almost simultaneously, Seitz was also appointed provisional chairman of the Social Democratic Workers' Party of Austria after the death of the party nestor Victor Adler. In 1919, his positions both as President of Austria and as party chairman were formalised.

Following the implementation of the definitive Constitution of Austria on 1 October 1920, Seitz declined to seek re-election. He left office on 9 December but did not retire from politics and retained both his party chairmanship and his seat in the newly established National Council, Seitz now devoted his attention to Vienna local affairs.

On 13 November 1923, he was elected Mayor of Vienna.^[2]

The extensive and competently administered public welfare and education programs that he implemented, particularly promoting the building of residences, were very popular, even by his party's opponents, and they were positively remembered for decades.

Karl Seitz married Emma Seidel, daughter of Amalie Seidel, one of the first women members of the Austrian parliament.

With the rise of the Fatherland Front in 1934 and the Social Democracts' failed insurrection against the federal government, the Social Democratic Worker's Party was outlawed. Having thus lost his party chairmanship, Seitz was also removed from his post as a mayor, taken into custody and released without charge a few weeks later. Even though a majority of Viennese considered his removal from office illegitimate, Seitz's political career had essentially been brought to an end.

Continuing to live in Vienna, Seitz witnessed the Anschluss with Nazi Germany in 1938 and the outbreak of World War II in 1939. There were contacts with the important resistance group (Maier-Mesner group, CASSIA) around the later-executed priest Heinrich Maier, who was in contact with the American secret service OSS. Maier had set up an information network to receive important information and to realise political plans for after the war.^[3] In 1944, he was placed under arrest a second time and for a time was even imprisoned in the Ravensbrück concentration camp, only to again return to Vienna when Nazi Germany eventually collapsed in May 1945. Though now ill, Seitz served the newly established Social Democratic Party of Austria as its honorary chairman and a nominal National Council member until his death, at the age of 80.^[2]
