Lord High Treasurer
Although the United Kingdom of Great Britain and Ireland was created in 1801, it was not until the Consolidated Fund Act 1816 that the separate offices of Lord High Treasurer of Great Britain and Lord High Treasurer of Ireland were united into one office as the "Lord High Treasurer of the United Kingdom of Great Britain and Ireland" on 5 January 1817.Other members of the government, usually whips in the House of Commons, are appointed to serve as the Junior Lords Commissioners of the Treasury.[2] The English Treasury seems to have come into existence around 1126, during the reign of Henry I, as the financial responsibilities were separated from the rest of the job that evolved into Lord Great Chamberlain.[3] During the sixteenth century, the Lord High Treasurer was often considered the most important official of the government, and became a de facto Prime Minister.Exemplifying the power of the Lord High Treasurer is William Cecil, 1st Baron Burghley, who served in the post from 1572 to 1598.
