Berwick-upon-Tweed is a town in the county of Northumberland and is the northernmost town in England, on the east coast at the mouth of the River Tweed. It is south of the Scottish border. It is about east-south east of Edinburgh, north of Newcastle upon Tyne and north of London.
Founded as an Anglo-Saxon settlement during the time of the kingdom of Northumbria, the area was for more than 400 years central to historic border war between the Kingdoms of England and Scotland, and several times possession of Berwick changed hands between the two kingdoms. The last time it changed hands was when England retook it in 1482. Berwick remains a traditional market town and also has some notable architectural features, in particular its medieval town walls, its Elizabethan ramparts and Britain's earliest barracks buildings (1717–21 by Nicholas Hawksmoor for the Board of Ordnance).
In the post-Roman period, the area was inhabited by the Brythons of Bryneich. Later, the region became part of the Anglian kingdom of Bernicia. Bernicia later united with the kingdom of Deira to form Northumbria, which in the mid-10th century entered the Kingdom of England under Eadred.
Between the late 10th and early 11th centuries, the land between the rivers Forth and Tweed came under Scottish control, either through conquest or through cession. Berwick was made a royal burgh in the reign of David I. A mint was present in the town by 1153.
Berwick's strategic position on the Anglo-Scottish border during centuries of war between the two nations and its relatively great wealth led to a succession of raids, sieges and takeovers. William I of Scotland invaded and attempted to capture northern England in 1173-74. After his defeat, Berwick was ceded to Henry II of England. It was later sold back to William by Richard I of England in order to raise funds for his Crusade. Berwick had become a prosperous town by the middle of the 13th century. According to William Edington, a bishop and chancellor of Scotland, Berwick was "so populous and of such commercial importance that it might rightly be called another Alexandria, whose riches were the sea and the water its walls". In 1291–92 Berwick was the site of Edward I of England's arbitration in the contest for the Scottish crown between John Balliol and Robert Bruce, 5th Lord of Annandale. The decision in favour of Balliol was pronounced in the Great Hall of Berwick Castle on 17 November 1292.
Between 1315 and 1318 Scottish armies, sometimes with the help of Flemish and German privateers, besieged and blockaded the town, finally invading and capturing it in April 1318. England retook Berwick some time shortly after the Battle of Halidon Hill in 1333. In October 1357 a treaty was signed at Berwick by which the Scottish estates undertook to pay 100,000 marks as a ransom for David II of Scotland, who had been taken prisoner at the Battle of Neville's Cross on 17 October 1346.
In 1461 Berwick was ceded back to Scotland by Margaret of Anjou on behalf of her husband, Henry VI, in return for help against the Yorkists during the Wars of the Roses. Robert Lauder of Edrington was put in charge of the castle. He was succeeded in 1474 by David, Earl of Crawford. On 3 February 1478, Robert Lauder of The Bass and Edrington was again appointed Keeper of the castle, a position that he held until the final year of Scottish occupation, when Patrick Hepburn, 1st Lord Hailes, had possession.
Berwick had a mediaeval hospital for the sick and poor which was administered by the Church. A charter under the Great Seal of Scotland, confirmed by King James I of Scotland, grants the king's chaplain "Thomas Lauder of the House of God or Hospital lying in the burgh of Berwick-upon-Tweed, to be held to him for the whole time of his life with all lands, teinds, rents and profits, etc., belonging to the said hospital, as freely as is granted to any other hospital in the Kingdom of Scotland; the king also commands all those concerned to pay to the grantee all things necessary for the support of the hospital. Dated at Edinburgh June 8, in the 20th year of his reign."
In 1551 the town was made a county corporate. During the reign of Queen Elizabeth I of England, vast sums – one source reports "£128,648, the most expensive undertaking of the Elizabethan period" – were spent on its fortifications, in a new Italian style (trace italienne), designed both to withstand artillery and to facilitate its use from within the fortifications. These fortifications have been described as "the only surviving walls of their kind". Sir Richard Lee designed some of the Elizabethan works.
In 1639 the army of Charles I faced that of General Alexander Leslie at Berwick in the Bishops' Wars, which were concerned with bringing the Presbyterian Church of Scotland under Charles's control. The two sides did not fight, but negotiated a settlement, "Pacification of Berwick", in June.
Holy Trinity Church was built in 1648–52; a rare example of a church being built in the Commonwealth period.
In 1707, the Act of Union between England and Scotland largely ended the contention about which of the countries Berwick belonged to. Since then, Berwick remained within the laws and legal system of England and Wales. The Wales and Berwick Act 1746 (since repealed) deemed that whenever legislation referred to England it applied to Berwick. England now is officially defined as "subject to any alteration of boundaries under Part IV of the Local Government Act 1972, the area consisting of the counties established by section 1 of that Act, Greater London and the Isles of Scilly.", which thus includes Berwick.
Berwick remained a county in its own right, and was not included in Northumberland for Parliamentary purposes until 1885. In the same year, the Redistribution of Seats Act reduced the number of Members of Parliament (MPs) returned by the town from two to one.
In 2008 Scottish National Party Member of Scottish Parliament (MSP) Christine Grahame made calls in the Scottish Parliament for Berwick to become part of Scotland again, saying, "Even the Berwick-upon-Tweed Borough Council leader, who is a Liberal Democrat, backs the idea and others see the merits of reunification with Scotland." The Liberal Democrat MSP Jeremy Purvis, who was born and brought up in Berwick, also asked for the border to be moved twenty miles south (i.e., a significant distance south of the Tweed) to include Berwick borough council rather than just the town. stating: "There’s a strong feeling that Berwick should be in Scotland. Until recently, I had a gran in Berwick and another in Kelso, and they could see that there were better public services in Scotland. Berwick as a borough council is going to be abolished and it would then be run from Morpeth, more than 30 miles away." However, Alan Beith, the Liberal Democrat MP for Berwick, said the move would require a massive legal upheaval and is not realistic. The issue was set to be the centre of a new BBC comedy-drama series, A Free Country, commissioned in 2008 from writer Tony Saint, but to date this project has vanished from view.
In 2009 the Borough of Berwick-upon-Tweed was abolished as part of wider structural changes to local government in England. All functions previously exercised by Berwick Borough Council were transferred to Northumberland County Council, which is the unitary authority for the area.
