  • July 12 – The Lords Justice in Great Britain attempt to curb some of the excesses of the stock markets during the South Sea Bubble. They dissolve a number of petitions for patents and charters, and abolish more than 80 joint-stock companies of dubious merit, but this has little effect on the creation of "Bubbles", ephemeral joint-stock companies created during the hysteria of the times.[2]
  • August 14 – The Spanish Villasur expedition, which set out on June 16 from New Mexico, with the intention of checking French influence on the Great Plains of North America, ends in failure, as it is ambushed by a Pawnee and Otoe force.
  • September – "South Sea Bubble": The English stock market crashes, with dropping prices for stock in the South Sea Company.

Calico Jack

John Rackham (26 December 1682 – 18 November 1720), commonly known as Calico Jack, was an English pirate captain operating in the Bahamas and in Cuba during the early 18th century. His nickname was derived from the calico clothing that he wore, while Jack is a nickname for "John".

Rackham was active towards the end (1718–1720) of the "Golden Age of Piracy" which lasted from 1650 to 1730. He is most remembered for having two female crew members: Mary Read and his lover, Anne Bonny.

Rackham deposed Charles Vane from his position as captain of the sloop Ranger, then cruised the Leeward Islands, Jamaica Channel and Windward Passage. He accepted a pardon in 1719 and moved to New Providence, where he met Anne Bonny, who was married to James Bonny at the time. He returned to piracy in 1720 by stealing a British sloop and Anne joined him. Their new crew included Mary Read, who was disguised as a man at the time. After a short run, Rackham was captured by Royal Navy pirate hunter Jonathan Barnet in 1720, put on trial by Sir Nicholas Lawes, Governor of Jamaica, and was hanged in November of that year in Port Royal, Jamaica.

Capture of the sloop William

The Capture of the sloop William refers to a small single ship action fought between Calico Jack's pirate ship and a British sloop-of-war from Port Royal, Jamaica. The battle was fought in Dry Harbor Bay, and ended with the capture of the famed pirate and his small crew of which several were hanged later on as a warning to other brigands.

Charles Edward Stuart

Charles Edward Louis John Casimir Sylvester Severino Maria Stuart (31 December 1720 – 31 January 1788) was the elder son of James Francis Edward Stuart, grandson of James II and VII and after 1766 the Stuart claimant to the throne of Great Britain. During his lifetime, he was also known as "The Young Pretender" or "The Young Chevalier" and in popular memory as "Bonnie Prince Charlie". He is best remembered for his role in the 1745 rising; his defeat at Culloden in April 1746 effectively ended the Stuart cause, and subsequent attempts (such as a planned French invasion in 1759) failed to materialise. His escape from Scotland after the uprising led him to be portrayed as a romantic figure of heroic failure in later representations.

Chinese expedition to Tibet (1720)

The 1720 Chinese expedition to Tibet or the Chinese conquest of Tibet in 1720 was a military expedition sent by the Qing dynasty to expel the invading forces of the Dzungar Khanate from Tibet and establish a Chinese protectorate over the country. The expedition occupied Lhasa and marked the beginning of Qing rule in Tibet, which lasted until the empire's fall in 1912.

List of Acts of the Parliament of Great Britain, 1720–1739

This is an incomplete list of Acts of the Parliament of Great Britain for the years 1720–1739. For Acts passed up until 1707 see List of Acts of the Parliament of England and List of Acts of the Parliament of Scotland. See also the List of Acts of the Parliament of Ireland to 1700 and the List of Acts of the Parliament of Ireland, 1701–1800.

For Acts passed from 1801 onwards see List of Acts of the Parliament of the United Kingdom. For Acts of the devolved parliaments and assemblies in the United Kingdom, see the List of Acts of the Scottish Parliament from 1999, the List of Acts of the Northern Ireland Assembly, and the List of Acts and Measures of the National Assembly for Wales; see also the List of Acts of the Parliament of Northern Ireland.

The number shown after each Act's title is its chapter number. Acts are cited using this number, preceded by the year(s) of the reign during which the relevant parliamentary session was held; thus the Union with Ireland Act 1800 is cited as "39 & 40 Geo. 3 c. 67", meaning the 67th Act passed during the session that started in the 39th year of the reign of George III and which finished in the 40th year of that reign. Note that the modern convention is to use Arabic numerals in citations (thus "41 Geo. 3" rather than "41 Geo. III"). Note also that Acts of the last session of the Parliament of Great Britain and the first session of the Parliament of the United Kingdom are both cited as "41 Geo. 3".

Acts passed by the Parliament of Great Britain did not have a short title; however, some of these Acts have subsequently been given a short title by Acts of the Parliament of the United Kingdom (such as the Short Titles Act 1896).

Before the Acts of Parliament (Commencement) Act 1793 came into force on 8 April 1793, Acts passed by the Parliament of Great Britain were deemed to have come into effect on the first day of the session in which they were passed. Because of this, the years given in the list below may in fact be the year before a particular Act was passed.

Sieges of Ceuta (1694–1727)

The Sieges of Ceuta (also known as the Thirty-year Siege) were a series of blockades by Moroccan forces of the Spanish-held city of Ceuta on the North African coast. The first siege began on 23 October 1694 and finished in 1720 when reinforcements arrived. During the 26 years of the siege, the city underwent changes leading to the loss of its Portuguese character. While most of the military operations took place around the city walls (Muralles Reales), there were also small-scale penetrations by Spanish forces at various points on the Moroccan coast, and seizure of shipping in the Strait of Gibraltar. The city was placed under a second siege in 1721 until 22 April 1727.

Treaties of Stockholm (Great Northern War)

The Treaties of Stockholm are two treaties signed in 1719 and 1720 that ended the war between Sweden and an alliance of Hanover and Prussia.

Aspects of the conflict that remained unresolved would be dealt with by two further treaties: the Treaty of Frederiksborg between Sweden and Denmark-Norway in 1720, which was a pure renewal of four previous treaties, Treaty of Copenhagen 1660, Malmö Recess 1662, Treaty of Fontainebleau 1679 and the Peace of Lund (written in Stockholm in 1679); and the Treaty of Nystad between Sweden and Russia in 1721.

Frederick I began negotiating the Treaties of Stockholm following the death of Charles XII of Sweden in 1718. The death of the Swedish monarch heralded the impending conclusion of the Great Northern War.

Treaty of Frederiksborg

The Treaty of Frederiksborg (Danish: Frederiksborgfreden) was a treaty signed at Frederiksborg Castle, Zealand, on 3 July 1720 (14 July 1720 according to the Gregorian calendar), ending the Great Northern War between Denmark-Norway and Sweden. Their Danish-Swedish part of the conflict began in 1700 but peace was restored the same year. Denmark rejoined the war in 1709 in a campaign to regain their lost provinces, Scania, Blekinge and Halland. However the Swedish general Magnus Stenbock managed to defend the provinces without presence of the king, Charles XII. On other fronts Sweden was not so lucky, primarily at the hands of Russia in 1721, and the destruction of the Swedish army from Stralsund, Swedish Pomerania.

Sweden paid 600,000 Riksdaler in damages (as deposit for this money, Denmark temporary had held Wismar, in Swedish Pomerania), broke her alliance with Holstein and forfeited her right to duty-free passage of Øresund. Denmark also gained full control over Schleswig, while Danish-held areas of Swedish Pomerania were returned to Sweden. The Treaty of Copenhagen from 1660, Malmö Recess 1662, Treaty of Fontainebleau (1679) and Stockholm also in 1679 (known as Peace of Lund) was now ratified for the fifth time.
