Robert Devereux, 2nd Earl of Essex in the context of "Earls of Essex"

Sir Edward Coke (/kʊk/ CUUK, formerly /kuːk/; 1 February 1552 – 3 September 1634) was an English barrister, judge, and politician. He is often considered the greatest jurist of the Elizabethan and Jacobean eras.

Born into an upper-class family, Coke was educated at Trinity College, Cambridge, before leaving to study at the Inner Temple, where he was called to the Bar on 20 April 1578. As a barrister, he took part in several notable cases, including Slade's Case, before earning enough political favour to be elected to Parliament, where he served first as Solicitor General and then as Speaker of the House of Commons. Following a promotion to Attorney General he led the prosecution in several notable cases, including those against Robert Devereux, Sir Walter Raleigh, and the Gunpowder Plot conspirators. As a reward for his services he was first knighted and then made Chief Justice of the Common Pleas.

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.

Francis Tresham (c. 1567 – 23 December 1605) was a member of the group of English provincial Catholics who planned the failed Gunpowder Plot of 1605, a conspiracy to assassinate King James I of England.

Tresham joined the Earl of Essex's failed rebellion against the government in 1601, for which he was imprisoned. Only his family's intervention and his father's money saved him from attainder. Despite this, he became involved in two missions to Catholic Spain to seek support for English Catholics (then heavily persecuted), and finally with the Gunpowder Plotters.

Originally called Leicester House, it was built around 1575 for Robert Dudley, 1st Earl of Leicester, and was renamed Essex House after being inherited by his stepson, Robert Devereux, 2nd Earl of Essex, after Leicester's death in 1588. The poet Philip Sidney lived in Leicester House for some time.

The property occupied the site where the Outer Temple, part of the London headquarters of the Knights Templar, had previously stood, and was immediately adjacent to the Middle Temple, one of the four Inns of Court. The house was substantial; in 1590, it was recorded as having 42 bedrooms, plus a picture gallery, kitchens, outhouses, a banqueting suite and a chapel.
