British Parliament

British Parliament the world's oldest
The Parliament of England traces its origin from the Anglo-Saxon Witenagemot. When William the Conqueror, who ruled England from 1066, there were large landowners and advice church hierarchs. In 1215, large landowners have John Lackland signing of the Magna Carta, according to which the king could appoint new taxes (except for some of the old feudal taxes) without the consent of the board of the Royal (royal court), which gradually evolved into a parliament.
In 1265, Simon de Montfort, 6th Earl of Leicester, has collected the first elected Parliament.
