Aislabie's family were originally Yeoman farmers who lived in Hemingbrough. His father George Aislebie married into the highly influential Mallory family through Mary Mallory, daughter of Sir John Mallory of Studley Royal. He was admitted at St. John's College, Cambridge in 1687 and at Trinity Hall, Cambridge in 1692. He inherited the Studley estate from his mother's family in 1693, and started serious development of the garden around 1716. He was the first in England to introduce natural landscaping and created the water garden at Studley Royal. His son, William Aislabie, added the ruins of Fountains Abbey to the estate.
Political career
Aislabie was elected as a Member of Parliament for Ripon at the 1695 English general election, apparently on the assumption he was a Tory, though his political views were somewhat fluid. He voted for the attainder of Sir John Fenwick on 25 November 1696. He was returned again for Ripon at the 1698 English general election. The loss of his wife and daughter in a house fire in January 1700 may have dampened his political activity for a while. He was returned again for Ripon at the two general elections of 1701, and he kept well enough in with Robert Harley to be classed as a Tory. He was elected Mayor of Ripon for the year 1702 to 1703, and was returned instead as MP for Northallerton at the 1702 English general election in an exchange deal with William Hustler. As mayor he was generous in paying for the reconstruction of the Market Cross, and making gifts to the Corporation. He became more active in politics from 1704, especially on the economy. At the 1705 English general election, he was returned again for Ripon and voted for the Court candidate as speaker on 25 October 1705. He eventually became associated with the CountryWhigs. Under the patronage of Robert Harley he was appointed a Lord of the Admiralty from 1710 in the Tory administration. This proved a precarious appointment as Aislabie's Whig sympathies manifested in votes against the government. When the Whigs returned to office in 1714, Aislabie was made Treasurer of the Navy. He became an ally of the Earl of Sunderland who became, in effect, Prime Minister in 1718. Sunderland appointed Aislabie as Chancellor of the Exchequer. When in 1719 the South Sea Company proposed a deal whereby it would take over the national debt in exchange for government bonds, Aislabie was a very strong supporter of the scheme and negotiated the contract; he piloted the Bill through the House of Commons. The South Sea Company had been built on high expectations which it could never fulfil, and it collapsed in August 1720. An investigation by Parliament found that Aislabie had been given £20,000 of company stock in exchange for his promotion of the scheme. He resigned the Exchequer in January 1721, and in March was found guilty by the Commons of the "most notorious, dangerous and infamous corruption". He was expelled from the House, removed from the Privy Council, and imprisoned in the Tower of London.
Later life and contributions
After his release from prison, he retired to his estate and continued the development of the gardens. The obeliskin the Market Square, Ripon, the first in England, was provided by John Aislabie in 1702, and is now grade I listed. In 1723 Aislabie constructed Waverley Abbey House on the site of former Cistercian Waverley Abbey in Surrey. John's son William Aislabie would also serve in Parliament for the Ripon constituency.
