The old social and political order was challenged by the creation of the USAQ (1776) and the French Revolution (1789); and the enlightenment thinking (which challenged theretofore beliefs)
The enlightenment encouraged people to question the divine right of kings (where monarchs said they were chosen by god to rule - monarchs and aristocrats had used this to remain in power)
The French Revolution released violence under ‘Liberty, fraternity, Equality’ these ideas spread (france was defeated in 1815 but liberal ideas continued)
Liberals wanted to belong to the party of ‘movement’ (not the party of ‘resistance‘) as they wanted a change in the system of government
liberals wanted power removed from the elite to be shared evenly in society (some wanted universal manhood sufferage, others wanted a republic or constitutional monarchy, others wanted the middle-class to hold political office)
The Carlsbad decrees were a reactionary response (by Metternich and William III) against the rise of liberalism (reactionary governments held from until 1848)
some liberal gains were made (in 1833 hanover gained its first constitution from king william, in the 1830s, 3 German states made their constitution more liberal, in Baden in 1846 press censorship was relaxed and police and judicial services reformed)
other liberal gains were made (in 1847 a liberal newspaper was published - ‘The german newspaper’ in Heidelberg; in 1847 was the Heppenheim meeting where liberals met from south west states demanding liberal reform in the national diet, armed forces, the press and taxation)
Frederick william III agreed to a meeting of the national diet in 1847, but he was afraid of the possible liberal ideas so disbanded the diet (this made liberals even more active)
Liberals were mostly middle-class people who wanted ‘equality’ (free trade, free press, office holding)
