The Polska Krajowa Kasa Pożyczkowa was established under German military occupation in December 1916 as the issuing authority for a new Polish currency — the marka — intended to replace the Russian ruble in the occupied territories. It was a political instrument as much as a financial one, designed to detach the local economy from Russian monetary structures while stopping well short of genuine Polish fiscal independence.

Printing at the S. Manitius press in Łódź rather than in Germany was a deliberate logistical choice given wartime conditions. Manitius was a known commercial printer, not a security printing specialist, and the notes from this series reflect that — they lack the intaglio depth of contemporary Western European currency and were relatively easy to counterfeit.
