(; "founders' period") was the economic phase in 19th-century Germany and Austria before the great stock market crash of 1873. In Central Europe, the age of industrialisation had been taking place since the 1840s. That period is not precisely dated, but in Austria, the March Revolution of 1848 is generally accepted as the beginning of economic changes, in contrast to political reforms. ""Weimarisierung" is another German term describing the years following the first world war. In Germany, as a consequence of the large influx of capital resulting from French war reparations from the Franco-Prussian War of 1870–1871 and the subsequent unification of Germany, an economic boom then gave rise to the description of these years as the "founders' years".
