Gavelkind

Gavelkind () was a system of land tenure chiefly associated with the Celtic law in Ireland and Wales and with the legal traditions of the English county of Kent.
The word may have originated from the Old Irish phrases "Gabhaltas-cinne" or "Gavail-kinne", which meant "family settlement" (Modern Gaelic "gabhail-cine"). The term came to describe all tenure and inheritance practices where land was divided equally among sons or other heirs.
Kent's inheritance pattern was a system of partible inheritance and bears a resemblance to Salic patrimony. As such, it might testify in favour of a wider Germanic tradition that was probably ancient. Over the centuries, various acts were passed to degavel individual manors, but the custom was only fully abolished in England and Wales by the Administration of Estates Act 1925.
Gavelkind in Kent.
Before the abolition of gavelkind tenure by the Administration of Estates Act 1925, all land in Kent was presumed to be held by gavelkind until the contrary was proved. It was more correctly described as socage tenure, subject to the custom of gavelkind. The chief peculiarities of the custom were the following:
Gavelkind, an example of customary law in England, was thought to have existed before the Norman Conquest of 1066, but was generally superseded by the feudal law of primogeniture introduced by the Normans. Its survival in Kent has been popularly attributed to a concession made to the people of the county by William the Conqueror, although this suggestion is now largely dismissed by scholars as legend.
Gavelkind in Wales.
In medieval Wales, a legal framework had developed based on the ancient Celtic laws and traditions similar to those in Ireland. These included a custom of gavelkind inheritance known as ".
"Cyfran" was an ancient tradition passed down orally by jurists and bards until the mid-10th century, when the laws were finally codified during the reign of Hywel Dda. The "Cyfraith Hywel" would become the most well-known and widely-adopted Welsh legal structure, and many of the laws were concerned with inheritance. The concept of "cyfran" stated that on a landowner's death, his land would be divided equally among all of the sons, including those who were illegitimate.
The continual division of lands and titles with each successive generation has been seen by some historians as detrimental to the success and stability of Welsh princes and lords, especially compared to the system of primogeniture practiced in Norman England and by the Marcher Lords, whose entire patrimony was often passed on directly to the eldest son. The Welsh historian Philip Yorke, writing in 1799, summarised the situation:
 
The Laws in Wales Acts 1535–1542 saw the Welsh legal system being replaced with English law, and the laws associated with gavelkind were replaced with those of primogeniture. However, as in England, the custom of gavelkind was not finally abolished until the Administration of Estates Act 1925.
Gavelkind in Ireland.
In Ireland, gavelkind was a species of tribal succession by which the land, instead of being divided at the death of the holder amongst his sons, was thrown again into the common stock and redivided among the surviving members of the sept.
Under Traditional Irish law, land was divided at the death of the holder among his sons. The Normans called the Irish inheritance law "gavelkind" because of its apparent similarity to Jutish gavelkind inheritance in Kent.
