The Treaty of Berwick is signed by England and the Lords of the Congregation of Scotland, establishing the terms under which English armed forces were to be permitted in Scotland in order to expel occupying French troops.

The Treaty of Berwick was negotiated on 27 February 1560 at Berwick-upon-Tweed. It was an agreement made by the representative of Queen Elizabeth I of England, the Duke of Norfolk, and a group of Scottish nobles, the Lords of the Congregation. The treaty set the terms under which an English fleet and army would come to Scotland to expel the French troops who were defending the Regency of Mary of Guise. The Lords were trying both to expel the French and to effect the Scottish Reformation, and this led to rioting and armed conflict.

England is a country that is part of the United Kingdom. It is located on the island of Great Britain, of which it covers about 62%, and more than 100 smaller adjacent islands. England shares a land border with Scotland to the north and another land border with Wales to the west, and is otherwise surrounded by the North Sea to the east, the English Channel to the south, the Celtic Sea to the south-west, and the Irish Sea to the west. Continental Europe lies to the south-east, and Ireland to the west. At the 2021 census, the population was 56,490,048. London is both the largest city and the capital.

The Lords of the Congregation, originally styling themselves the Faithful, were a group of Protestant Scottish nobles who in the mid-16th century favoured a reformation of the Catholic church according to Protestant principles and a Scottish-English alliance. The Confederate Lords were nobles who opposed Mary, Queen of Scots, after she married the Earl of Bothwell.

Scotland is a country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent islands, principally in the archipelagos of the Hebrides and the Northern Isles. In 2022, the country's population was about 5.4 million. Its capital city is Edinburgh, whilst Glasgow is the largest city and the most populous of the cities of Scotland. To the south-east, Scotland has its only land border, which is 96 miles (154 km) long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The legislature, the Scottish Parliament, elects 129 MSPs to represent 73 constituencies across the country.
