A geographic barony is a remnant from mediaeval times of the area of land held under the form of feudal land tenure termed feudal barony, or barony by tenure, either an English feudal barony, a Scottish feudal barony or an Irish feudal barony, which all operated under different legal and social systems. Just as modern counties are no longer under the administrative control of a noble count or earl, geographic baronies are generally no longer connected with feudal barons, certainly not in England where such tenure was abolished with the whole feudal system by the Tenures Abolition Act 1660. The position in Scotland is more complex, although the legal force of the Scottish feudal baron was abolished early in the 21st century.
The hectare (/ˈhɛktɛər/ or /ˈhɛktɑːr/), although not a unit of SI, is the only named unit of area that is accepted for use within the SI. In practice the hectare is fully derived from the SI, being equivalent to a square hectometre. It is widely used throughout the world for the measurement of large areas of land, and it is the legal unit of measure in domains concerned with land ownership, planning, and management, including law (land deeds), agriculture, forestry, and town planning throughout the European Union. The United Kingdom, United States, Burma, and to some extent Canada instead use the acre.
