Final answer:
Early 19th century British and European liberals were mostly educated elites from the middle classes who advocated for freedoms from various forms of restrictions, desiring a constitutional monarchy with limited voting rights to property-owning men. They opposed broad representation, excluding the working classes and women from the electorate.
Step-by-step explanation:
The individuals that comprised the early 19th century liberals in Britain and Europe included educated men and women, particularly the elites of industry, trade, professions, and the middle classes. These liberals were inspired by the Enlightenment and held the belief that freedom - from despotic monarchy, noble privilege, economic, religious interference, and restrictions on occupation, speech, and assembly - was essential for the improvement of society. They envisioned a constitutionally limited monarchy as opposed to a full democracy, and thus believed that voting rights should be constrained to property-owning men, which they thought would assure social stability by keeping the governance in the hands of those with economic interests.
Regarding representation in government, early 19th century liberals were against broad democratic participation, specifically opposing the notion that all individuals should have the right to vote. Instead, they believed in a restricted electorate where only males with substantial property ownership could vote, thus blocking representation from the working classes, women, and those who were property-less.
In Britain, the Great Reform Bill of 1832 was a response to liberal pressure, expanding the electorate to include most of the urban middle class and eliminating the "rotten boroughs". Nonetheless, throughout Europe, liberal reforms were enacted gradually and often incompletely. For instance, elected parliaments were introduced, but with electorates limited to property owners, excluding women until the 20th century.
