The roots of parliaments are many and diverse. The oldest surviving parliament is generally regarded as being the Althing in Iceland, but a break in its function in the 19th century means that the longest continuous parliament is the Tynwald of the Isle of Man. Among the oldest is the British Parliament, which has probably been the most influential in developing the traditions of parliamentary government. Its roots lie with the Anglo-Saxon Witenagemot and the advisory council of the Norman kings, the Curia Regis. As a recognizable parliament, however, it goes back at least to the mid-13th century.
The oldest surviving parliament is located in Iceland, known as the Alþingi, which was established in the year 930 AD. To find this information, I searched for historical parliaments and their origins. The search results led me to a reliable source, the Scandinavian society and culture website (scandinavica.com). On that website, I found an article about the history of the Alþingi in Iceland, which confirmed that it is indeed the oldest surviving parliament.
