The Great Seal of the Realm or Great Seal of the United Kingdom (known prior to the Treaty of Union of 1707 as the Great Seal of England; and from then until the Union of 1801 as the Great Seal of Great Britain) is a seal that is used to symbolise the Sovereign's approval of state documents. Scotland has had its own great seal since the 14th century. The Acts of Union 1707, joining the kingdoms of Scotland and England, provided for the use of a single Great Seal for the new Kingdom of Great Britain. However, it also provided for the continued use of a separate Scottish seal to be used there, and this seal continues to be called the Great Seal of Scotland, although it is not technically one. Similarly, a separate Great Seal of Ireland, which had been used in Ireland since the 13th century, continued in use after the union of 1801, until the secession of the Irish Free State, after which a new Great Seal of Northern Ireland was created for use in Northern Ireland. A new Welsh Seal was introduced in 2011. Sealing wax is melted in a metal mould or matrix and impressed into a wax figure that is attached by cord or ribbon to documents that the Monarch wishes to seal officially. The formal keeper of the seal is the Lord High Chancellor of Great Britain. History At some time before the year 1066 Edward the Confessor began to use a "Great Seal", which created a casting in wax of his own face, to signify that a document carried the force of his will. With some exceptions, each subsequent monarch up to 1603, when the king of Scotland succeeded to the throne of England, chose his or her own design for the Great Seal. Levina Teerlinc is believed to have designed the seal of Queen Mary I, and also the earliest seal used by her successor Elizabeth I, in the 1540s. When opening Parliament on 3 September 1654, the Lord Protector Oliver Cromwell was escorted by the three "Commissioners of the Great Seal of the Commonwealth of England", who were Whitelock, Lisle, and Widdrington. This Seal was inscribed with 'The Great Seal of England, 1648', displaying a map of England, Ireland, Jersey, and Guernsey on one side, with the Arms of England and Ireland. On the other side was shown the interior
