Robert Devereux, 2nd Earl of Essex (; 10 November 1565 – 25 February 1601) was an English army officer who was a favourite of Queen Elizabeth I.

A charismatic and ambitious youth, Essex grew up in a family of courtiers with strong ties to the Queen. He became a royal ward following his father's death in 1576. He entered court in 1585 as a member of the Earl of Leicester's entourage. Essex rose quickly at court and developed a close personal relationship with the Queen. He played a prominent role in England's military campaigns during the Anglo-Spanish War and Eighty Years' War, including expeditions to Portugal and the Azores, particularly a victory at Cádiz, which gave him celebrity status among the London elite.

Towards the end of the 1590s, Essex's position at court was threatened by Robert Cecil. Essex was appointed Lord Deputy of Ireland during the Nine Years' War. Despite considerable resources, his 1599 campaign against the Irish confederacy was a military disaster, ruining his reputation and straining his relationship with the Queen. He deserted his post and was subsequently placed under house arrest, leading to a nervous breakdown. In February 1601, he led a failed coup against the government and was arrested, tried for treason, and executed by beheading at the Tower of London.

The nature of Essex's turbulent relationship with Elizabeth has been the subject of speculation by both historians and dramatists.

Early life and education

Robert Devereux was born on 10 November 1565 at Netherwood in Herefordshire, the eldest son of Walter Devereux, 1st Earl of Essex, and his wife Lettice Knollys. From birth, the young Robert Devereux had a strong association with Queen Elizabeth I. Lettice was a close friend of Elizabeth and served as her Maid of the Privy Chamber. Robert Devereux was presumably named after his godfather Robert Dudley, Earl of Leicester, who was the Queen's favourite for many years. Additionally, Devereux's maternal great-grandmother Mary Boleyn was a sister of Elizabeth's mother Anne Boleyn, making him a first-cousin-twice-removed of the Queen.

Devereux had two older sisters, Penelope and Dorothy, a younger brother, Walter, and another brother Francis who died soon after birth. Devereux and his siblings were brought up at the family seat at Chartley in Staffordshire. From 1573, Devereux's father, Walter, was involved in a scheme to colonise Ulster and thus spent much of his time in Ireland.

Walter died in September 1576. Ten-year-old Robert Devereux—who acceded to the earldom as 2nd Earl of Essex—became a ward of the Crown. Prominent minister Lord Burghley was Master of the Court of Wards and thus took on chief responsibility for young Essex's welfare. He was also brought up by leading courtiers Thomas Radclyffe, 3rd Earl of Sussex and Henry Hastings, 3rd Earl of Huntingdon. Essex was an intelligent and promising child; a report of November 1576 described him as "very courteous and modest, rather disposed to hear than to answer, given greatly to learning, weak and tender, but very comely and beautiful". By this time, he could speak both Latin and French.

Essex's late father had crippled his family's finances and left the young earl £18,000 in debt. His father's legal advisor Richard Broughton oversaw the family estate whilst he was still a minor. In January 1577, Essex left Chartley to travel to London, where he briefly stayed at Burghley's residence Cecil House. He also spent time at Theobalds, Burghley's estate in Hertfordshire, where he mixed with Burghley's son Robert Cecil.

As a boy he was tutored by Thomas Ashton, headmaster of Shrewsbury School and a family servant, then by Ashton's protégé Robert Wright. In early May 1577, Essex entered Trinity College, Cambridge. He matriculated by 1579, and in 1581 he graduated with a Master of Arts. He spent the next four years travelling the British countryside.

Early career

Apprenticeship in Netherlands

He joined the entourage of his new stepfather Leicester (Lettice and Leicester married in 1578) and visited the royal court in September 1585. Leicester became a significant patron for his stepson, and he instilled in Essex a sense of unity with fellow Protestants across Europe. Despite his later status as a royal favourite, Essex went unnoticed by the Queen in his early visits to court; she was preoccupied by both the Anglo-Spanish War and the Eighty Years' War.

Essex was granted permission to accompany Leicester on a military apprenticeship in the Spanish Netherlands. He was appointed colonel-general of the English cavalry in the Netherlands, a prestigious position which signified his status as Leicester's new protégé. In September 1586, Essex and his horsemen successfully attacked a much larger Spanish force in the Battle of Zutphen, for which Leicester made him a knight-banneret. Leicester's nephew Philip Sidney, a beloved courtier mortally wounded at Zutphen, bequeathed one of his best swords to Essex. In effect, Sidney transferred to Essex his dual roles as England's champion of Protestantism and Leicester's right-hand man.

Royal favourite

Essex returned to England as a war hero in late October 1586 and quickly caught the Queen's eye. Women were susceptible to Essex's looks and charm, and Elizabeth was no exception. His attention, which made the aging Queen feel young again, was a welcome distraction from her angst over the impending execution of Mary, Queen of Scots. Leicester, himself a former favourite, backed Essex at court to further his own interests and weaken the standing of his rival Walter Raleigh. By May 1587, Essex was a constant companion of Elizabeth, and all through the summer they were observed riding and walking together.The extent of Elizabeth's leniency towards Essex is evident from the outcome of a furious argument between the two in July 1587, where Essex criticised her attachment to Raleigh. Essex rode off to join the Siege of Sluis, but was stopped at the coast by a courtier sent by the Queen. Essex apparently suffered no serious consequences and was back at court within days. Leicester convinced Elizabeth to appoint Essex as Master of the Horse, which ensured a close attendance with the Queen and boosted Essex's pay by about £1500
