Hide (unit)

Hide (unit) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hide (unit) rather than just read about it. In short: The hide (or mansa) is an archaic English unit of land measurement originally intended to represent the amount of land sufficient to support a household. It is a measure of value and tax assessment, including obligations for food-rent (feorm), maintenance and repair of bridges and fortifications, manpower for the army (fyrd), and (eventually) the geld land tax.

Key takeaways

  • Hide (unit) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hide (unit) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hide (unit) from memory before moving on to harder problems.

Reference excerpt

The hide (or mansa) is an archaic English unit of land measurement originally intended to represent the amount of land sufficient to support a household. It is a measure of value and tax assessment, including obligations for food-rent (feorm), maintenance and repair of bridges and fortifications, manpower for the army (fyrd), and (eventually) the geld land tax. The hide was divided into four yardlands or virgates. It was hence nominally equivalent in area to a carucate, a unit used in the Danelaw. The hide's method of calculation is now obscure: different properties with the same hidage could vary greatly in extent even in the same county. Following the Norman Conquest of England, the hidage assessments were recorded in the Domesday Book of 1086, and there was a tendency for land producing £1 of income per year to be assessed at 1 hide. The Norman kings continued to use the unit for their tax assessments until the end of the 12th century.

Original meaning The Anglo-Saxon word for a hide was hid (or its synonym hiwisc). Both words are believed to be derived from the same root hiwan, meaning "family". Bede in his Ecclesiastical History (c. 731) describes the extent of a territory by the number of families which it supported, as (for instance), in Latin, terra x familiarum meaning 'a territory of ten families'. In the Anglo-Saxon version of the same work hid or hiwan is used in place of terra ... familiarum. Other documents of the period show the same equivalence and it is clear that the word hide originally signified land sufficient for the support of a peasant and his household or of a family, which may have had an extended meaning. It is uncertain whether it meant the immediate family or a more extensive group. Charles-Edwards suggests that in its early usage it referred to the land of one family, worked by one plough and that ownership of a hide conferred the status of a freeman, whom Stenton refers as "the independent master of a peasant household".

Holy Roman Empire Hides of land formed the basis for tax levies used to equip free warriors (milites) of the Holy Roman Empire. In 807 it was specified that in the region west of the Seine, for example, a vassal who held four or five hides was responsible for showing up to a muster in person, fully equipped for war. Three men who each possessed one hide were grouped such that two of them were responsible for equipping the third, who would go to war in their name. Those holding half-hides were responsible for readying one man for every group of six. This came about as a way of ensuring that the liege took to the field with a fully equipped and provisioned force.

The furlong (meaning furrow length) was the distance a team of oxen could plough without resting.  This was standardised to be exactly 40 rods or 10 chains.
An acre was the amount of land tillable by one man behind one team of eight oxen in one day.  Traditional acres were long and narrow due to the difficulty in turning the plough and the value of river front access.
An oxgang was the amount of land tillable by one ox in a ploughing season.  This could vary from village to village, but was typically around 15 acres.
A virgate was the amount of land tillable by two oxen in a ploughing season.
A carucate was the amount of land tillable by a team of eight oxen in a ploughing season.  This was equal to 8 oxgangs or 4 virgates.

Worked examples

Example 1 — a first encounter with Hide (unit)

Start with the simplest possible case. Write down what Hide (unit) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hide (unit) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hide (unit) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hide (unit)

In research
Hide (unit) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hide (unit) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hide (unit) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Obsolete English units of measurement, Types of administrative division, Units of area, so understanding it makes those chapters shorter.
In everyday life
Look for Hide (unit) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
