Overview

The Parliament of Great Britain was the single legislature that governed the kingdom created by the 1707 union of England (which included Wales) and Scotland. It existed from 1707 until 1801 and replaced the separate parliaments of England and Scotland. Sitting at the historic Palace of Westminster in the City of Westminster, this Parliament combined representatives drawn from across Great Britain and exercised legislative authority for the new state.

Composition and institutions

The Parliament was bicameral, made up of two houses. The House of Commons consisted of elected Members of Parliament who represented counties and boroughs across Great Britain. The House of Lords comprised the Lords Temporal (secular peers) and Lords Spiritual (bishops of the Church of England). Bishops of the Church of England sat in the Lords as part of the established church for England and Wales; the Church of Scotland, which had a different ecclesiastical structure, did not send bishops to the Lords.

The body was created after both the Parliament of England and the Parliament of Scotland agreed to the terms set out in the Treaty of Union. Each legislature enacted corresponding measures—commonly known as the Acts of Union 1707—to dissolve the separate parliaments and form a new, single Parliament for the Kingdom of Great Britain. The new institution took over legislative powers and responsibilities previously exercised by the two former parliaments.

Functions and developments

As the national legislature, the Parliament of Great Britain passed laws affecting trade, taxation, defence, and civil rights within the kingdom. The eighteenth century saw important political developments within its operation: the gradual strengthening of collective cabinet government, the emergence of a leading ministerial figure often called the prime minister, and shifting patterns of party and factional alignment. Parliamentary business was shaped by patronage, electoral arrangements such as borough representation, and the privileges of the Houses. Debates occurred both within formal sessions and in wider public life, influencing governance and policy.

Dissolution and legacy

The Parliament of Great Britain continued until a further union with the kingdom of Ireland created a larger parliamentary body. Legislation passed at the turn of the nineteenth century merged the Parliament of Great Britain with the Parliament of Ireland to establish the Parliament of the United Kingdom, effective 1 January 1801. Many institutional practices, privileges, and precedents developed during the 1707–1801 period carried forward into the later United Kingdom Parliament and helped shape modern British parliamentary government.
