Guy Fawkes in the context of "Robert Catesby"

Westminster Hall is a medieval great hall which forms part of the Palace of Westminster in London. It was built in 1097 for William II, and at that time was one of the largest halls in Europe. It is particularly notable for its hammerbeam roof, which was commissioned for Richard II in 1393 and built by the royal carpenter, Hugh Herland. At the same time the rest of the hall was remodelled by the master mason Henry Yevele. The hall survived the fire of 1834 and bombing in World War II and, in spite of various restorations, has maintained its medieval structure and many of its features.

The hall has served a variety of ceremonial and administrative functions throughout its history. From the twelfth to the nineteenth centuries it was home to the courts of King's Bench, Chancery, and Common Pleas. It was the scene of important state trials, including those of Thomas More,Guy Fawkes and King Charles I. Banquets and royal entertainments were hosted in the hall, with the last coronation banquet being that of George IV in 1821. Since the twentieth century, the hall has been the venue for the lyings in state of state funerals. It is used for special addresses by Parliament to the monarch, and is on rare occasions the venue for joint addresses to the two chambers of Parliament.

The Gunpowder Plot of 1605, in earlier centuries often called the Gunpowder Treason Plot or the Jesuit Treason, was an unsuccessful attempted regicide against King James VI of Scotland and I of England by a group of English Catholics, led by Robert Catesby.

The plan was to blow up the House of Lords during the State Opening of Parliament on Tuesday 5 November 1605, as the prelude to a popular revolt in the Midlands during which King James's nine-year-old daughter, Elizabeth, was to be installed as the new head of state. Catesby is suspected by historians to have embarked on the scheme after hopes of greater religious tolerance under James had faded, leaving many English Catholics disappointed. His fellow conspirators were John and Christopher Wright, Robert and Thomas Wintour, Thomas Percy, Guy Fawkes, Robert Keyes, Thomas Bates, John Grant, Ambrose Rookwood, Sir Everard Digby and Francis Tresham. Fawkes, who had 10 years of military experience fighting in the Spanish Netherlands in the failed suppression of the Dutch Revolt, was given charge of the explosives.

Old Palace Yard is a paved open space in the City of Westminster, England. It lies between the Palace of Westminster to its north and east and Westminster Abbey to its west. It is known as the site of executions, including those of Sir Walter Raleigh, Guy Fawkes and other conspirators of the Gunpowder Plot, and James Hamilton, 1st Duke of Hamilton, following the Battle of Preston.

St Margaret Street/Abingdon Street divides Old Palace Yard into two parts, running diagonally from the north-west to the south-east. The eastern, larger part belongs to the grounds of the Palace of Westminster, the seat of the Parliament of the United Kingdom. To the north of the Yard is St Stephen's Entrance, the public entrance into the Palace, as well as the great South Window of Westminster Hall. Standing near this window and facing away from it is a bronze equestrian statue of Richard Coeur de Lion (King Richard I, also known as "Richard the Lionheart"). Created by Baron Carlo Marochetti, the statue was completed in 1856 and installed in its present location in 1860. The eastern side of Old Palace Yard is defined by the West Front of the Palace, which is part of the precincts of the House of Lords; the carriage porch of the Peers' Entrance marks the middle of this frontage, and the Victoria Tower its southern end.

John Wright (January 1568 – 8 November 1605), and Christopher Wright (1570? – 8 November 1605), were brothers and members of the group of provincial English Catholics who planned the failed Gunpowder Plot of 1605, a conspiracy to assassinate King James I by blowing up the House of Lords. Their sister married another plotter, Thomas Percy. Educated at the same school in York, the Wrights had early links with Guy Fawkes, the man left in charge of the explosives stored in the undercroft beneath the House of Lords. As known recusants the brothers were on several occasions arrested for reasons of national security. Both were also members of the Earl of Essex's rebellion of 1601.

John was one of the first men to join the conspiracy, which was led by Robert Catesby. Christopher joined in March 1605. At about midnight on 4 November Fawkes was discovered and arrested, following which John, Christopher and the rest of the conspirators travelled across the Midlands, attempting to gain support for a popular uprising. Eventually the group opted to wait for the authorities at Holbeche House, on the border of Staffordshire. On 8 November the Sheriff of Worcester arrived with a large group of armed men, and both brothers were killed in the ensuing firefight.

Robert Wintour (1568 – 30 January 1606) and Thomas Wintour (1571 or 1572 – 31 January 1606), also spelt Winter, were members of the Gunpowder Plot, a failed conspiracy to assassinate King James I. They were brothers, and related to other conspirators, such as their cousin, Robert Catesby; a half-brother, John Wintour, also joined them following the plot's failure. Thomas was an intelligent and educated man, fluent in several languages and trained as a lawyer, but chose instead to become a soldier, fighting for England in the Low Countries, France, and possibly in Central Europe. By 1600, however, he changed his mind and became a fervent Catholic. On several occasions he travelled to the continent and entreated Spain on behalf of England's oppressed Catholics, and suggested that with Spanish support a Catholic rebellion was likely.

As momentum was building behind a peace settlement between the two countries, Thomas's pleas were ignored. Instead, in 1604 he decided to join with Catesby, who planned to restore England to Catholicism by killing the king and inciting a popular revolt in the Midlands, during which James's daughter, Princess Elizabeth, would be installed as titular queen. Thomas returned to the continent and again failed to elicit Spanish support, but instead met Guy Fawkes, with whom he returned to England. Robert, a devout Catholic who inherited Huddington Court near Worcester, joined the conspiracy the following year.

Thomas Bates (1567 – 30 January 1606) was a member of the group of provincial English Catholics who planned the failed Gunpowder Plot of 1605.

Bates was born at Lapworth in Warwickshire, and became a retainer to Robert Catesby, who from 1604 planned to kill King James I by blowing up the House of Lords with gunpowder, and inciting a popular revolt during which a Catholic monarch would be restored to the English throne. Bates was invited to join the conspiracy after he accidentally became aware of it. As he rode with Catesby to prepare for the group's planned uprising on 5 November 1605, Guy Fawkes was found guarding the gunpowder stored under the House of Lords and arrested. Bates subsequently accompanied Catesby and his small group of fugitives to Holbeche House in Staffordshire, but left shortly before his master was killed there by government forces on 8 November. He was subsequently captured and taken to London.

John Grant (c. 1570 – 30 January 1606) was a member of the failed Gunpowder Plot, a conspiracy to replace the Protestant King James I of England with a Catholic monarch. Grant was born around 1570, and lived at Norbrook in Warwickshire. He married the sister of another plotter, Thomas Wintour. Grant was enlisted by Robert Catesby, a religious zealot who had grown so impatient with James's lack of toleration for Catholics that he planned to kill him, by blowing up the House of Lords with gunpowder. Grant's role in the conspiracy was to provide supplies for a planned Midlands uprising, during which James's daughter, Princess Elizabeth, would be captured. However, on the eve of the planned explosion, Guy Fawkes was discovered guarding the explosives the plotters had positioned in the undercroft beneath the House of Lords, and arrested.

As the government searched for Fawkes's accomplices, Grant and the others engaged in a futile mission for support for the uprising. They stole horses from Warwick Castle, and further supplies from Hewell Grange, before stopping at Holbeche House. The plotters laid in front of the fire some of the gunpowder they had collected, to dry out, but a stray spark ignited the powder, and in the resultant conflagration Grant was blinded. Government forces besieged the house, and he was captured and taken to London.
