The Dette Publique Ottomane — the Ottoman Public Debt Administration — was not a Turkish institution in any ordinary sense. Established by European creditors in 1881 after the empire defaulted on its foreign loans, it functioned as a state-within-a-state, collecting specific tax revenues directly on behalf of bondholders in Paris, London, and Vienna. That this body was still issuing paper currency as late as 1918, with the empire collapsing and Allied forces closing in, is the detail that makes the series historically arresting.
By the final year of the war, severe coin shortages had forced emergency paper into denominations that would normally never exist as banknotes. The OPDA's wartime issues were effectively a fiscal stopgap for a government that had long since lost control of its own monetary apparatus.
