of Parliament is one of long competition with the
monarchy, and Parliament's eventual supremacy. Important milestones in that competition include:
the early Commons' assertion of control over grants of revenue to the monarch;
the English Civil war when Parliament ordered the beheading of the king;
the Glorious Revolution of 1688, during which Parliament succeeded in establishing its sovereignty over the Crown;
the growing dependence of the Prime Minister on Parliament in the 18th century;
the great reforms of the 19th century, which extended suffrage to most of the adult male population and established the secret ballot;
the Parliament Act of 1911, which abolished the veto power of the Lords;
the Representation of the People Acts of 1918, 1928, 1948, and 1969, which extended the suffrage to women, established the principle of one person one vote, and lowered the voting age from 21 to 18.
Major parliamentary reforms of 1999-2003 initiated by the Labour Government.
