Italy's 1866 unification finances were in crisis almost immediately. The Third Italian War of Independence, fought that same year alongside Prussia against Austria, forced the government to suspend specie convertibility in May 1866 — the so-called "corso forzoso" — marking the first time Italy issued inconvertible paper money as a unified state. This note was part of that emergency emission.

At 60 × 24 mm, it belongs to a class of fractional currency more akin to stamped tickets than banknotes. The Officina Carte Valori in Turin handled production throughout, but the extreme format created persistent counterfeiting problems and significant public resistance from a population that had barely accepted paper money at all.
