The Battle of Barnet was a decisive engagement in the Wars of the Roses, a dynastic conflict of 15th-century England. The military action, along with the subsequent Battle of Tewkesbury, secured the throne for Edward IV. On 14 April 1471 near Barnet, then a small Hertfordshire town north of London, Edward led the House of York in a fight against the House of Lancaster, which backed Henry VI for the throne. Leading the Lancastrian army was Richard Neville, Earl of Warwick, who played a crucial role in the fate of each king. Historians regard the battle as one of the most important clashes in the Wars of the Roses, since it brought about a decisive turn in the fortunes of the two houses. Edward's victory was followed by 14 years of Yorkist rule over England.

The siege of Sidney Street of January 1911, also known as the Battle of Stepney, was a gunfight in the East End of London between a combined police and army force and two Latvian revolutionaries. The siege was the culmination of a series of events that began in December 1910, with an attempted jewellery robbery at Houndsditch in the City of London by a gang of Latvian immigrants which resulted in the murder of three policemen, the wounding of two others, and the death of George Gardstein, the leader of the Latvian gang.

The Blitz was a German bombing campaign against the United Kingdom in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term "Blitzkrieg", the German word for 'lightning war'.

The Battle of Brentford was a small pitched battle which took place on 12 November 1642, between a detachment of the Royalist army under the command of Prince Rupert, and two infantry regiments of Parliamentarians with some horse in support. The result was a victory for the Royalists.

The Battle of Brentford was fought in 1016 some time between 9 May and 18 October between the English led by Edmund Ironside and the Danes led by Canute. It was one of a series of battles fought between Edmund and Canute, ultimately resulting in the lands held by Edmund's father Æthelred the Unready being divided between the two. Edmund was victorious in this particular battle, but ultimately failed to defend the lands inherited from his father. "Then collected he [Edmund] his force the third time, and went to London, all by north of the Thames, and so out through Clayhanger, and relieved the citizens, driving the enemy to their ships. It was within two nights after that the king went over at Brentford; where he fought with the enemy, and put them to flight: but there many of the English were drowned, from their own carelessness; who went before the main army with a design to plunder." (Anglo-Saxon Chronicle)

Jack Cade's Rebellion was a popular revolt in 1450 against the government of England, which took place in the south-east of the country between the months of April and July. It stemmed from local grievances regarding the corruption, maladministration and abuse of power of the king's closest advisors and local officials, as well as recent military losses in France during the Hundred Years' War. Leading an army of men from south-eastern England, the rebellion's namesake and leader Jack Cade marched on London in order to force the government to reform the administration and remove from power the "traitors" deemed responsible for bad governance. It was the largest popular uprising to take place in England during the 15th century.

In the autumn of 1016, the Danish prince Cnut the Great (Canute) successfully invaded England. Cnut's father, Sweyn Forkbeard, had previously conquered and briefly ruled England for less than five weeks.

The Cornish rebellion of 1497, also known as the "First Cornish rebellion of 1497", was a popular uprising that began in Cornwall in the south-west of England and culminated with the Battle of Deptford Bridge near London on 17 June 1497.

The Gordon Riots of 1780 were several days of rioting in London motivated by anti-Catholic sentiment. They began with a large and orderly protest against the Papists Act of 1778, which was intended to reduce official discrimination against British Catholics enacted by the Popery Act 1698. Lord George Gordon, head of the Protestant Association, argued that the law would enable Catholics to join the British Army and plot treason. The protest led to widespread rioting and looting, including attacks on Newgate Prison and the Bank of England and was the most destructive in the history of London.

The Iranian Embassy siege took place from 30 April to 5 May 1980, after a group of six armed men stormed the Iranian embassy on Prince's Gate in South Kensington, London. The gunmen, Iranian Arabs campaigning for sovereignty of Khuzestan Province, took 26 people hostage, including embassy staff, several visitors, and a police officer who had been guarding the embassy. They demanded the release of prisoners in Khuzestan and their own safe passage out of the United Kingdom. The British government quickly decided that safe passage would not be granted and a siege ensued. Subsequently, police negotiators secured the release of five hostages in exchange for minor concessions, such as the broadcasting of the hostage-takers' demands on British television.

The Oldcastle Revolt was a Lollard uprising directed against the Catholic Church and the English king, Henry V. The revolt was led by John Oldcastle, taking place on the night of 9/10 January 1414. The rebellion was crushed following a decisive battle on St. Giles's Fields.

Sir John Oldcastle was an English Lollard leader. Being a friend of Henry V, he long escaped prosecution for heresy. When convicted, he escaped from the Tower of London and then led a rebellion against the King. Eventually, he was captured and executed in London. He formed the basis for William Shakespeare's character John Falstaff, who was originally called John Oldcastle.

The Peasants' Revolt, also named Wat Tyler's Rebellion or the Great Rising, was a major uprising across large parts of England in 1381. The revolt had various causes, including the socio-economic and political tensions generated by the Black Death in the 1340s, the high taxes resulting from the conflict with France during the Hundred Years' War, and instability within the local leadership of London.

The Second Great Fire of London in December 1940 was one of the most destructive air raids of the Blitz during World War II. The Luftwaffe raid caused fires over an area greater than that of the Great Fire of London in 1666, leading one American correspondent to say in a cable to his office that "The second Great Fire of London has begun". Fires started by the raid included an incendiary bomb that broke through the dome of St Paul's Cathedral, which was being guarded by a fire watch team at the behest of the Prime Minister Winston Churchill.

The siege was the culmination of a series of events that began in December 1910, with an attempted jewellery robbery at Houndsditch in the City of London by a gang of Latvian immigrants which resulted in the murder of three policemen, the wounding of two others, and the death of George Gardstein, the leader of the Latvian gang.
The Battle of Turnham Green took place on 13 November 1642 near the village of Turnham Green, at the end of the first campaigning season of the First English Civil War. The battle resulted in a standoff between the forces of King Charles I and the much larger Parliamentarian army under the command of the Earl of Essex. In blocking the Royalist army's way to London immediately, however, the Parliamentarians gained an important strategic victory as the standoff forced Charles and his army to retreat to Oxford for secure winter quarters.

Thomas Venner was a cooper and rebel who became the last leader of the Fifth Monarchy Men, who tried unsuccessfully to overthrow Oliver Cromwell in 1657, and subsequently led a coup in London against the newly restored government of Charles II. This event, known as "Venner's Rising", lasted four days before the Royal authorities captured the rebels. The rebel leadership suffered execution on 19 January 1661.
