The Treaty of London (), signed on 18 August O.S. (28 August N.S.) 1604,see Old Style and New Style dates: the date in brackets the Gregorian Calendar used in Spain but not in England or Scotland at that timeRatified by the King of Spain on and ratified on 5/15 June 1605 and by King James I on 19/29 August 1604Davenport, pp. 246– 257 concluded the nineteen-year Anglo-Spanish War soon after the death of the childless Elizabeth I of England and the accession of James VI of Scotland to the throne of England in 1603 as James I. The treaty restored the status quo between the two nations prior to the war. The negotiations probably took place at Somerset House in Westminster and are sometimes known as the Somerset House Conference.
Background The Anglo-Spanish War, starting in 1585 had been complex and fluctuating conflict that also had connections with the Dutch Revolt, the French Wars of Religion, and the Nine Years' War in Ireland. By 1598, neither side had secured a decisive advantage; however, a series of events would pave the way for peace. France, England and the Dutch Republic had signed an alliance two years previous in their fight against Spain. France however went behind the backs of England and the Dutch and ended their war with Spain with the Peace of Vervins which was signed in 1598. As a result, England and the Dutch Republic signed the Treaty of Westminster later that year, renewing the military alliance. The treaty however reduced England's military commitment in the Low Countries as the Dutch states were in a much stronger position than it had been in 1585. Since then and with English help, the Dutch had reconquered, as well as captured, large swatches of territory from the Spanish. The Dutch also consented that there would be no restraint if England made a separate peace with Spain provided there was reduced instalments of Dutch debt to England.
For Spain, change was also in the air; the war by 1596 had taken a downturn. The defeat at Cadiz, and the failure of their 2nd armada had sent the nation into bankruptcy. The 3rd Spanish armada sent the following year was also a costly disaster, which affected the health of King Philip II and from which he never recovered. On September 1598, his death brought a significant change. The new young King Phillip III carried on the war, but his court was now dominated by the Duke of Lerma whose general policy was one of disengagement. In 1599, the Spanish Empire suffered further financial strain. As such, there was rebellious opposition for the King's request for money, which saw Spanish troops mutiny in the Netherlands. In addition, there was the fear of a new war with France over the Duchy of Saluzzo. All of these combined to emphasise the hopelessness of inflicting a vital blow on England.
Early peace proposals In April 1600, Archduke Albert, the governor of the Spanish Netherlands, opened secret negotiations with England for a settlement but did not inform Madrid.Maltby p. 120 The following month, negotiations culminated in a meeting of a conference at BourbourgMotley's "History of the United Netherlands", p.108 (ed. 1862) between representatives of Spain, England and Burgundy.
Bourbourg was chosen as it was a personal possession of the Kings of France from 1562 despite being under the sovereignty of Spain. This continued until 1659 when the town was reincorporated into the French kingdom.
Spain demanded the cession of the Cautionary Towns. England demanded free trade with Spain and her empire, freedom of English subjects from the inquisition and the exclusive right of having warships in the channel. The talks got nowhere, Spain contended that it was absurd to expect the sovereign of a worldwide empire to give the pas to a queen of a few islands. By August the talks were off – mutual distrust and United Provinces pressure made any agreement impossible. Despite this however diplomatic routes were open between England, Albert, and his wife, Isabella Clara Eugenia (Philip's sister). Letters from representatives showed that Albert, Isabella Clara Eugenia, and Philip were still anxious for peace despite their difference in policies. Philip wanted to preserve the hegemony of the Spanish empire, whilst the Archduke and Isabella sought peace and friendly relations.McCoog pp. 222–23
The concern of the government in Madrid was to improve their dire military situation in the Netherlands by reducing or stopping English help to the Dutch rebels.Brown, Elliott, Museo del Prado p. 14 Meanwhile, Johan van Oldenbarnevelt, heading the delegation of the States of Holland, tried to attract the complicity of the new English monarch in the conflict in Flanders, of which the focus was the Siege of Ostend.Fissel pp. 186–87 The siege had become a struggle of bloody attrition after just over two years.Rowse p. 413 Spain had also sent their 4th Spanish Armada in 1601 this time to Ireland in the hope of assisting the Irish rebels, who were fighting to rid England's rule. The town of Kinsale was held, and besieged by English forces led by the Earl of Mountjoy. The expedition ended in defeat when Kinsale surrendered in 1602. The defeat thus further weakened Spanish resolve in the war against England.
After the death of Queen Elizabeth I in 1603, her successor, James I, quickly sought to end the long and draining conflict. By this time Spanish hopes of a decisive military victory in the Netherlands, or a successful invasion of England, were relatively remote. James, an idealistic Protestant practitioner of Christian peace and unity, was the son and successor to the Catholic Mary, Queen of Scots, whose execution had been a proximate cause of the conflict. Philip III warmly welcomed the offer and ordered the commencement of the difficult negotiations that followed.
Treaty The first moves towards a treaty were taken in June 1603, when Juan de Tassis headed a Spanish–Flemish Commission which visited London, seeking truces and mutual good faith. Tassis was despatched to England by Philip III to explore the possibilities for a settlement following Elizabeth's death.van Nimwegen p. 187
Archduke Albert had already sent his envoy Charles de Ligne, prince-count of Arenberg, to London and was joined by Juan de Tassis, in September 1603. Although De Tassis lacked full negotiating powers he was active behind the scene the following month in preparation for a settlement.
At the end of 1603, the constable of Castile arrived in Brussels with the authorisation to conclude the treaty if one could be negotiated. On 19 May 1604, with the constable still waiting in the wings, the rest of the Habsburg delegation arrived in London and the English negotiating team was appointed. The meetings took place in Somerset House, probably in the hall used by the Queen's council.Susan Doran, From Tudor to Stuart: The Regime Change from Elizabeth I to James I (Oxford, 2024), p. 440.

Terms Spain recognizes the Protestant monarchy of England and renounces intentions to restore the Church of Rome in the country. An end to Spanish military intervention in Ireland.O'Connor p. 63 An end to English disruption to Spanish trans-Atlantic shipping and colonial expansion (article 6)."The first item of James' agenda was to bring to a close the long standing war with Spain. This was done by the Treaty of London in August 1604. Its terms were flagantry generous to the Spanish, the first black mark against the new king. Moreover James, unlike Elizabeth, had every intention of honoring them." Burgess, Douglas: The Pirates' Pact: The Secret Alliances Between History's Most Notorious Buccaneers and Colonial America. McGraw-Hill Professional, 2008, page 29. Channing, Edward: A history of the United States. Octagon Books, 1977, v. 1, page 158. The English Channel opened to Spanish shipping. An end to English intervention in the Dutch Revolt (articles 4,5,7); England withdraws military and financial support to the Dutch rebels. Ships of both countries, merchants or warships, could use the mainland seaports of the other party for refit, shelter or buy provisions (article 10). Fleets of less than eight ships did not even have to ask for permission, which provided an extensive network of naval bases for the Spaniards in England to help their war against the Protestant Dutch.
The treaty was signed on 28 August (New Style), at Whitehall Palace, by the Constable of Castile who was lodged at Somerset House.Janette Dillon, The Language of Space in Court Performance, 1400–1625 (Cambridge, 2010), pp. 83–89.Thomas Rymer, Foedera, 16, p. 629 The treaty restored the status quo ante bellum.Hiram Morgan, 'Teaching the Armada: An Introduction to the Anglo-Spanish War, 1585-1604', History Ireland, Vol. 14, No. 5 (Sep. - Oct., 2006), p. 43.Paul Allen, Philip III and the Pax Hispanica, 1598-1621 (New Haven, 2000). It amounted to an acknowledgement by Spain that its hopes of restoring Roman Catholicism in England were at an end and it had to recognise the Protestant monarchy in England. In return, England ended its financial and military support for the Dutch rebellion, ongoing since the Treaty of Nonsuch (1585), and had to end its wartime disruption of Spanish trans-Atlantic shipping and colonial expansion.
Aftermath With England out of the way, the Spanish hoped for a knock-out blow that would force the Dutch into a peace by launching a huge campaign led by Ambrogio Spinola in 1606.Allen pp. 142-43 James still allowed the Dutch army to recruit English volunteer soldiers in their service – 8,000 having served in the Netherlands in 1605.Dunthorne p. 65 In addition, English corsairs were now finding their needs in the service of the Dutch, who preyed on Spanish shipping. Conversely, Spanish warships and privateers were allowed to use English ports as naval bases to attack Dutch shipping or to transport reinforcements to Flanders. In November 1607, the costs of the recent wars with France, the Protestant Dutch as well as England resulted in Spain's bankruptcy. The Twelve Years' Truce was thus signed, which formally recognized the independence of the Dutch Republic.
