The term 'écu' may refer to one of several
French coins. The first écu was a
gold coin (the ''écu d'or'') minted during the reign of
Louis IX of France, in
1266. ''Ecu'' (from
Latin ''scutum'') means shield, and the coin was so called because its design included a shield bearing a
coat of arms. The word is related to
scudo and
escudo. The value of the écu varied considerably over time, and
silver coins (known as ''écu d'argent'') were also introduced.
In the
17th and
18th centuries, the name ''écu'' was applied exclusively to a large silver coin (introduced by
Louis XIII in
1640) initially worth three ''
livres tournois''. From 1690 to 1725 rates were unstable and new écus were issued, and existing écus revalued. After
1726 the final écu remained stable at six ''
livres tournois''. The silver ''écu'' (sometimes also called the ''
louis d'argent'') was further broken down into a 1/4 value coin (the ''quart d'écu'') and a 1/2 value coin (the ''demi-écu''). For more on the 17-18th century currency system, see
Louis (coin),
livre tournois and
Italian scudo.
The ''écu'' disappeared during the
French Revolution, but the 5 francs silver coins minted throughout the
19th century were but the continuation of the old ''écus'', and were often still called ''écu'' by French people.
The ''écu'', as it existed immediately before the
French Revolution, is approximately equivalent (in terms of purchasing power) to 20
euros or 25
dollars in
2006.
