Ostrubel (German and Polish: German: Ostrubel; Latvian and Lithuanian: Latvian: Ostrublis; Russian: Острубль) is the name given to a currency denominated in copecks and rubels, which was issued by Germany in 1916 for use in the eastern areas under German occupation (German: [[Ober Ost]] and the Government General of Warsaw). It was initially equal to the Imperial rouble. The reason for the issue was a shortage of currency. The banknotes were produced by the German: Darlehnskasse in German: Posen (now Polish: [[Poznań]]) on 17 April 1916.
From 4 April 1916, the German: Ostrubel circulated alongside the German: [[German ostmark|Ostmark]] in the German: [[Ober Ost]] area, with German: 2 Ostmarken = 1 German: Ostrubel. In the Government General of Warsaw the German: Ostruble was replaced by the Polish Polish: marka|nocat=y on 14 April 1917.
The banknote denominations available were:
The front sides of the banknotes carry a warning in German against forging banknotes. On the reverse sides is the same warning in Latvian (with old style orthography), Lithuanian and Polish.
There were also 1 copeck, 2 copeck and 3 copeck coins, made out of iron.
The German: Ostrubel circulated in Lithuania together with the Ostmark until 1 October 1922, when it was replaced by the Lithuanian: [[Lithuanian litas|litas]].
It was also still in use in a part of the Second Polish Republic during the first months of independence, until 29 April 1920.
