until 1750. The Central Council of Ukraine, or the Central Rada, founded on March 4, 1917, was the All-Ukrainian council of the Ukrainian People's Republic, which declared its full state independence in the Fourth Universal of the Ukrainian Central Council in 1918. The contemporary Ukrainian parliament is called the Verkhovna Rada of Ukraine. Development of modern parliaments The development of the modern concept of parliamentary government dates back to the Kingdom of Great Britain (1707–1800). United Kingdom The British Parliament is often referred to as the Mother of Parliaments (in fact a misquotation of John Bright, who remarked in 1865 that "England is the Mother of Parliaments") because the British Parliament has been the model for most other parliamentary systems, and its Acts have created many other parliaments. Many nations with parliaments have to some degree emulated the British "three-tier" model known as the Westminster system. Most countries in Europe and the Commonwealth have similarly organised parliaments with a largely ceremonial head of state who formally opens and closes parliament, a large elected lower house and a smaller, upper house. The Parliament of Great Britain was formed in 1707 by the Acts of Union that replaced the former parliaments of England and Scotland. A further union in 1801 united the Parliament of Great Britain and the Parliament of Ireland into a Parliament of the United Kingdom. In the United Kingdom, Parliament consists of the House of Commons, the House of Lords, and the Monarch. The House of Commons is composed of 650 (soon to be 600) members who are directly elected by British citizens to represent single-member constituencies. The leader of a Party that wins more than half the seats, or less than half but is able to gain the support of smaller parties to achieve a majority in the house is invited by the Monarch to form a government. The House of Lords is a body of long-serving, unelected members: Lords Temporal – 92 of whom inherit their titles (and of whom 90 are elected internally by members of the House to lifetime seats), 588 of whom have been appointed to lifetime seats, and Lords Spiritual – 26 bishops, who are part of the house while they remain in office. Legislation can originate from either the Lords or the Commons. It is voted on in several distinct stages, called readings, in each house. First reading is merely a formality.
