Thomas Wriothesley, 1st Earl of Southampton, English politician, Lord Chancellor of the United Kingdom (born 1505)

Thomas Wriothesley, 1st Earl of Southampton, was an English peer, secretary of state, Lord Chancellor and Lord High Admiral. A naturally skilled but unscrupulous and devious politician who changed with the times, Wriothesley served as a loyal instrument of King Henry VIII in the latter's break with the Catholic Church. Richly rewarded with royal gains from the Dissolution of the Monasteries, he nevertheless prosecuted Calvinists and other Protestants when political winds changed.

The Lord Chancellor, formally titled Lord High Chancellor of Great Britain, is a senior minister of the Crown within the Government of the United Kingdom. The lord chancellor is the minister of justice for England and Wales and the highest-ranking Great Officer of State in Scotland and England, nominally outranking the prime minister. The lord chancellor is appointed and dismissed by the sovereign on the advice of the prime minister. Prior to the union of England and Scotland into the Kingdom of Great Britain, there were separate lord chancellors for the Kingdom of England and the Kingdom of Scotland. Likewise, the Lordship of Ireland and its successor states maintained the office of lord chancellor of Ireland until the establishment of the Irish Free State in 1922, whereupon the office was abolished.
