The role of prime minister was not formally defined at first. Sir Robert Walpole is generally considered the first holder of the office, though the position evolved gradually from senior ministers advising the monarch.
Over time, power shifted from the Crown to Parliament, and the prime minister became the central figure in British government. The rise of organised political parties, electoral reform in the nineteenth century, and the expansion of democracy all reshaped the office into its modern form.
