Parliamentary system

Origin
Over the course of the centuries from the Magna Carta to the present day, the parliamentary system of government evolved in England as a method of, first limiting, and at last, virtually replacing, the absolute power of the monarchy with representative democratic rule. At the time of the American Revolution, this system was still very much in transition, and it has undergone significant changes since then. Many countries have adopted some variation upon a parliamentary democracy as their system of government; indeed, it can be argued that, for all of its multitudinous differences in detail, the American presidential system is the direct offspring of the British parliamentary system, and resembles its parent in many ways. See Wikipedia: Parliamentary System.
Countries of the Commonwealth have, for the most part, adopted a form of parliamentary democracy much like that in the UK: this is usually called the Westminster System. Yet, each of these countries (for instance, Australia, Canada, India, Jamaica, Malaysia, New Zealand, and Singapore) has made some local changes to the Westminster System, which results in a different political dynamic.
