Anglo-Saxon charters are documents from the early medieval period in England, which typically made a grant of land, or recorded a privilege. The earliest surviving charters were drawn up in the 670s: the oldest surviving charters granted land to the Church, but from the eighth century, surviving charters were increasingly used to grant land to lay people.
The term charter covers a range of written legal documentation including diplomas, writs and wills. A diploma was a royal charter that granted rights over land or other privileges by the king, whereas a writ was an instruction (or prohibition) by the king which may have contained evidence of rights or privileges. Diplomas were usually written on parchment in Latin, but often contained sections in the vernacular, describing the bounds of estates, which often correspond closely to modern parish boundaries. The writ was authenticated by a seal and gradually replaced the diploma as evidence of land tenure during the late Anglo-Saxon and early Norman periods. Land held by virtue of a charter was known as bookland.
Charters have provided historians with fundamental source material for understanding Anglo-Saxon England, complementing the Anglo-Saxon Chronicle and other literary sources. They are catalogued in Peter Sawyer's Annotated List and are usually referred to by their Sawyer number (e.g. S407).
The Anglo-Saxon charter can take many forms: it can be a lease (often presented as a chirograph), a will, an agreement, a writ or, most commonly, a grant of land. Our picture is skewed towards those that regard land, particularly in the earlier period (though it must also be admitted that the emergence of wills and chirorographs also owed much to later development). Land charters can further be subdivided into royal charters, or diplomas, and private charters (donations by figures other than the king).
