The Parliament of England was the legislature of the Kingdom of England, existing from the early 13th century until 1707, when it became the Parliament of Great Britain after the political union of England and Scotland created the Kingdom of Great Britain. 

In 1066, William of Normandy introduced what, in later centuries, became referred to as a feudal system, by which he sought the advice of a council of tenants-in-chief (a person who held land) and ecclesiastics before making laws. In 1215, the tenants-in-chief secured Magna Carta from King John, which established that the king may not levy or collect any taxes (except the feudal taxes to which they were hitherto accustomed), save with the consent of his royal council, which gradually developed into a parliament. 

Over the centuries, the English Parliament progressively limited the power of the English monarchy which arguably culminated in the English Civil War and the trial and execution of Charles I in 1649. After the restoration of the monarchy under Charles II, and the subsequent Glorious Revolution of 1688, the supremacy of Parliament was a settled principle and all future English and later British sovereigns were restricted to the role of constitutional monarchs with limited executive authority. The Act of Union 1707 merged the English Parliament with the Parliament of Scotland to form the Parliament of Great Britain. When the Parliament of Ireland was abolished in 1801, its former members were merged into what was now called the Parliament of the United Kingdom.
