An assignat [asiɲa] was a type of a monetary instrument used during the time of the French Revolution, and the French Revolutionary Wars.
Assignats were paper money issued by the National Assembly in France from 1789 to 1796, during the French Revolution. Backed by the value of properties formerly held by the Catholic Church, the assignats were immediately a source of political controversy. While their proponents, like other eighteenth-century advocates of "land banks," argued that land was a more stable source of value than was gold or silver, the assignats' opponents saw them as based on an illegitimate seizure of property.
Originally meant as bonds, the assignats were re-defined as legal tender (assignats-monnaie) in April 1790 to address the liquidity crisis provoked by the political, social, and cultural instability of the Revolution. As soon as the assignats started to circulate, their value decreased by 5 percent. When the cost of reimbursing Old Regime venal office holders for their properties (judgeships, military ranks etc.) added yet more to the Revolution's inherited debts, the National Assembly voted by a narrow margin to issue additional assignats in Sept. 1790.By September 1791, the value of the assignats had depreciated by 18-20 percent.
The properties backing the assignats were renamed biens nationaux (“national goods”) and auctioned by district-level authorities. Through the sale of these properties, assignats were used to successfully retire a significant portion of the national debt. However, since these land sales were their original intent, the assignats were issued only in large denominations (50, 100, 200, and 1000 livres) that worked poorly as a daily medium of exchange. Moreover, the National Assembly never mandated that assignats and Old Regime coins (which remained in circulation) had to be exchanged on par. Already in fall 1790, the National Assembly itself was paying a 7.5% commission to exchange large denomination assignats for smaller coins. By the end of 1791, the discount rate was often 20% or more. These limits on the bills' practical use, coupled with the organized opposition of counter-revolutionaries, led to their losing value. Patriotic revolutionaries blamed the assignats' depreciation on foreign conspiracies. There was some basis for these suspicions. The British, Belgian, and Swiss counterfeited the currency industrially - according to Dillaye: “Seventeen manufacturing establishments were in full operation in London, with a force of four hundred men devoted to the production of false and forged Assignats.”
