British Parliamentary Democracy
British parliamentary democracy, developed from Magna Carta (1215) through the Glorious Revolution (1688) to the Reform Acts of the 19th century, is the political system in which Parliament holds sovereign authority over the Crown, constitutional conventions constrain executive power without a written constitution, and gradual democratic expansion extended the franchise from aristocracy through the middle class to universal suffrage, providing the template for parliamentary governance adopted by Canada, Australia, India, and most of the Commonwealth.
Parliamentary sovereignty, the principle that Parliament can enact any law and no court can strike it down as unconstitutional (unlike American judicial review), is the defining feature of the Westminster system. This sovereignty was established through the Glorious Revolution (1688): William III accepted the English throne on parliamentary terms, signing the Bill of Rights (1689) that explicitly stated parliamentary authority over royal prerogative. The constitutional settlement was unwritten but real: the monarch reigns but does not govern; the Prime Minister governs by maintaining parliamentary confidence rather than serving at royal pleasure.
The democratic expansion was gradual and contested: the Great Reform Act (1832) broke the rotten boroughs (constituencies with few voters electing MPs) and extended the franchise to middle-class property-owners; the Second Reform Act (1867) extended it to working-class urban men; the Third Reform Act (1884) to rural workers; women gained partial suffrage in 1918 and equal suffrage in 1928. This incremental expansion, each extension producing demands for the next, is the characteristic pattern of British constitutional development: reform just sufficient to defuse immediate pressure, never enough to satisfy the next generation.
Predictive History's analysis: the British parliamentary tradition is the practical expression of the common law mentality, constitutional development through accumulated precedent and incremental reform rather than revolutionary rupture. The contrast with the French constitutional tradition (France has had 5 republics, 2 empires, and 3 monarchies since 1789; the UK has had the same constitutional framework since 1689) reflects genuinely different political cultures: British conservatism and gradualism vs. French revolutionary willingness to remake the political order from first principles.
