In 1908, Gregor Zerjav became the chief coordinator of the National Progressive Party in Carniola. Despite his young age, he became one of the main financial advisors of the Slovene national liberal political establishment. In 1910, he became notorious for his involvement in the bankruptcy of the Agro Merkur credit bank, established a few years earlier as a financial institution supporting the National Progressive Party.[1]
In 1911, he was elected to the Austrian parliament, where he became the leader of the 'Yugoslav Club', a caucus of South Slav national liberal representatives from the Slovene Lands, Istria, and Dalmatia.
After the outbreak of World War I, Žerjav launched an underground network which was working against the Austro-Hungarian Monarchy in favour of the creation of a unified Yugoslav state.[2] Among his closest collaborators in this endeavour were two other radical liberal nationalists from the younger generation, Albert Kramer and Bogumil Vošnjak.[3] The Austro-Hungarian authorities never disclosed the network. However, already in the first moths of the war, Žerjav was preventively arrested and imprisoned in Ljubljana Castle for his "notorious pro-Serbian attitudes". He was released after less than a month. In May 1915, when his colleague Bogumil Vošnjak fled to the west in order to join the Yugoslav Committee, Žerjav was again arrested and put into custody in the town of Gmund and later in Graz, where he spent most of the war.
He was elected to the Yugoslav parliament for three consecutive terms, in 1920, 1925, and 1927 (the first time as representative of the Democratic Party, and the last two on the list of the Independent Democratic Party. From December 1921 to December 1922, he served as the Minister for Welfare, and between November 1924 and July 1925 as Minister of Forestry and Mining in the Democratic-Radical coalition governments of Nikola Pašić.
Private life
Gregor Žerjav was married to Milena Žerjav, née Lavrenčič. The couple had three children, first Borut, then the twins Nadina and Tatjana (born 5 March 1912 in Gorizia).
The last years of his life he suffered tuberculosis; for an attempt of operative surgery he went to Berlin to the Charité as one of the first patients of Ferdinand Sauerbruch when using the iron lung there.
About half a year later he died in his estate in Poljče near Radovljica, and was buried in Žale Cemetery in Ljubljana.
His wife and this daughter Tatjana also died of tuberculosis later on.
