Ideas of national unity in early-nineteenth-century Europe were closely allied to the ideology of liberalism. The term 'liberalism' derives from the Latin root liber, meaning free. For the new middle classes liberalism stood for freedom for the individual and equality of all before the law. Politically, it emphasised the concept of government by consent. Since the French Revolution, liberalism had stood for the end of autocracy and clerical privileges, a constitution and representative government through parliament. Nineteenth-century liberals also stressed the inviolability of private property. Yet, equality before the law did not necessarily stand for universal suffrage.
Men without property and all women were excluded from political rights. Only for a brief period under the Jacobins did all adult males enjoy suffrage. However, the Napoleonic Code went back to limited suffrage and reduced women to the status of a minor, subject to the authority of fathers and husbands. Throughout the nineteenth and early twentieth centuries women and non-propertied men organised opposition movements demanding equal political rights.
