Anton Lipošćak, was an Austro-Hungarian Army General of the Infantry of Croatian descent who served as the Governor-General of the Military Government of Lublin during the World War I. After the war, Lipošćak returned to Zagreb where the State of Slovenes, Croats and Serbs declared independence from Austria-Hungary. He was accused of plotting a coup d'état and arrested. Most present-day sources consider the charges false. The charges were dropped and Lipošćak released in two months, in early 1919.

The Kingdom of Poland, also known informally as the Regency Kingdom of Poland, was a short-lived polity that was proclaimed during World War I by the German Empire and Austria-Hungary on 5 November 1916 on the territories of formerly Russian-ruled Congress Poland held by the Central Powers as the Government General of Warsaw and which became active on 14 January 1917. It was subsequently transformed between 7 October 1918 and 22 November 1918 into the independent Second Polish Republic, the customary ceremonial founding date of the latter being later set at 11 November 1918.
