Though inspired very generally by the ideas of liberal nationalism and democracy, the mostly middle-class demonstrators of 1848 had, like their Arab contemporaries, very different goals in different countries. In Hungary, they demanded independence from Habsburg Austria. In what is now Germany, they aimed to unify the German-speaking peoples into a single state. In France, they wanted to overthrow the monarchy (again). In some countries, revolution led to pitched battles between different ethnic groups. Others were brought to a halt by outside intervention.
In fact, most of the 1848 rebellions failed... Historian A.J.P. Taylor once called 1848 a moment when "history reached a turning point and failed to turn."
And yet--in the longer run, the ideas discussed in 1848 did seep into the culture... In 1849, many of the revolutions of 1848 might have seemed disastrous, but looking back from 1899 or 1919, they seemed like the beginning of a successful change.
