[1] After unsuccessfully running for a seat in the Diet of Hungary, his agitation on behalf of Slovak causes led to him being imprisoned for a year in 1906 along with Andrej Hlinka, on the grounds of "instigation against the Magyar nationality".

[1] Slovak aspirations towards independence continued to simmer during the First World War, accompanied by the rise of an agrarian movement with which Šrobár was involved.

By the end of the war the Austro-Hungarian Empire was beginning to disintegrate and on 1 May 1918 Šrobár proclaimed the Slovak people's right to self-determination and to create a common state with the Czechs.

[1] Šrobár was appointed the Slovak chairman of the CNR[1] and signed the new Czechoslovak state's proclamation of independence, which was read out in Prague on 28 October.

[4] He was not by any means a major political figure in Slovakia at the time and his involvement only a few days after his release from prison was quite fortuitous, as he later recalled: Around 24 October an unclear and vague unrest caught hold of me.

He retained both posts until 1920 and contributed significantly to the establishment of Czechoslovak rule in Slovakia, exercising virtually dictatorial powers on behalf of the Prague government.

[7] He dissolved the Slovak National Council on 8 January 1919 as part of a centralising drive, for which he was widely criticised,[8] and a year later Slovakia itself was abolished as an administrative unit under the new constitution.

He published a two-volume work, Oslobodené Slovensko (Liberated Slovakia), between 1928 and 1932, and in 1935 he was appointed by Comenius University as a tenured professor for the history of medicine.

[1] During the Second World War, when Slovakia was a nominally independent pro-Nazi puppet state, Šrobár was discreetly active as a supporter of the anti-fascist Czechoslovak opposition.

[2] Šrobár also founded the Catholic Freedom Party in 1946, which later merged into the Czechoslovak National Front, and published an autobiography, Z môjho života (From My Life) in the same year.
