Ottoman Public Debt Administration
Ottoman Public Debt Administration (OPDA) was a European-controlled organization that was established in 1881 to collect the payments which the Ottoman Empire owed to European companies in the Ottoman public debt. The OPDA became a vast, essentially independent, bureaucracy within the Ottoman bureaucracy, run by the creditors: Its governing council included one representative each from British, French, German, Austrian, Italian, Dutch, and Ottoman creditors, and one representative from the Ottoman state.
