The gulden first emerged as a common currency of the
Holy Roman Empire after the 1524 in the form of the . In the succeeding centuries the gulden was then defined as a fraction of the specie or silver coin. As of 1690 the gulden used in Southern Germany and the
Habsburg monarchy adhered to the Leipzig standard, with the gulden worth of a
Cologne Mark of fine silver or of a specie coin, or 12.992 g per gulden. Below is a history (in terms of grams of silver) of the standards of the Austro-Hungarian gulden from 1690 until the gold standard was introduced in 1892. A comparison with the lower-valued
South German gulden is also included. The course of value of the gulden before 1618 is found under . : The gulden departed from the Leipzig standard in the 1730s when the gold to silver price ratio dropped from 15 to 14.5, prompting several states to reissue their gulden in cheaper gold. The Austro-Hungarian gulden then departed from its South German counterpart after it valued the
Carolin d'or of 7.51 g fine gold at 9 Austrian gulden, versus 11 gulden in Southern Germany. This made the Austrian gulden worth = 0.834 g fine gold, or = 12.1 g fine silver. As Austria was the leading state of the
Holy Roman Empire, it initiated the currency convention of 1754 in which the replaced the
reichsthaler specie as the standard currency of the Holy Roman Empire. The was defined as half of a Conventionsthaler, equivalent to of a
Cologne mark of
silver, or 11.6928 g. The
South German gulden was set lower at 24 guldens per
Cologne mark of silver, or 2.4 guldens per Conventionsthaler, or 9.744 g. The
North German Reichsthaler currency unit was then defined as Gulden or Conventionsthaler, or 17.5392 g. Following the winding up of the Holy Roman Empire in 1806, the Gulden became the standard unit of account in the Habsburg lands and remained so until 1892. The gulden was subdivided in 60 , each of 4 or 8
heller. In 1857, the was introduced across the
German Confederation and Austria-Hungary, with a silver content of
grams. This was slightly less than times the silver content of the Gulden. Consequently, Austria-Hungary adopted a new standard for the gulden, containing two-thirds as much silver as the Vereinsthaler, or g. This involved a
debasement of the currency of 4.97%. Austria-Hungary also
decimalized at the same time, resulting in a new currency system of 100 kreuzer = 1 gulden and gulden = 1 . In 1892 the Austro-Hungarian gulden was replaced by the
krone, with each krone containing grams of gold, at a rate of 1 gulden = 2 kronen (gold–silver ratio 18.2). In 1946 the
Hungarian forint () was reintroduced and remains the official
currency in
Hungary. ==Coins==
