Q:Information:  - This is a list of historic counties of England by area according to the Arrowsmith map of 1815 - 6 , which was in turn generated from the work of the Ordnance Survey .  - An earl is a member of the nobility. The title is Anglo-Saxon in origin, akin to the Scandinavian form jarl, and meant "chieftain", particularly a chieftain set to rule a territory in a king's stead. In Scandinavia, it became obsolete in the Middle Ages and was replaced by duke ("hertig"/"hertug"/"hertog"). In later medieval Britain, it became the equivalent of the continental count (in England in the earlier period, it was more akin to a duke; in Scotland it assimilated the concept of mormaer). However, earlier in Scandinavia, "jarl" could also mean a sovereign prince. For example, the rulers of several of the petty kingdoms of Norway had the title of "jarl" and in many cases they had no less power than their neighbours who had the title of king. Alternative names for the "Earl/Count" rank in the nobility structure are used in other countries, such as Hakushaku during the Japanese Imperial era.  - Ordnance Survey (OS) is the national mapping agency for Great Britain and is one of the world's largest producers of maps. Since 1 April 2015 it has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remain accountable to the Secretary of State for Business, Energy and Industrial Strategy. It is also a member of the Public Data Group.  - The world is the planet Earth and all life upon it, including human civilization. In a philosophical context, the world is the whole of the physical Universe, or an ontological world. In a theological context, the "world" is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.  - Counties of England are areas used for the purposes of administrative, geographical, cultural or political demarcation.  - The Anglo-Saxons are a people who have inhabited Great Britain from the 5th century. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.  - The Normans (Norman: "Nourmands"; ) were the people who, in the 10th and 11th centuries, gave their name to Normandy, a region in France. They were descended from Norse ("Norman" comes from "Norseman") raiders and pirates from Denmark, Iceland and Norway who, under their leader Rollo, agreed to swear fealty to King Charles III of West Francia. Through generations of assimilation and mixing with the native Frankish and Gallo-Roman populations, their descendants would gradually adopt the Carolingian-based cultures of West Francia, ultimately resulting in their own assimilation into the Romance society. The distinct cultural and ethnic identity of the Normans emerged initially in the first half of the 10th century, and it continued to evolve over the succeeding centuries.  - Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago.  - The historic counties of England were established for administration by the Normans, in most cases based on earlier kingdoms and shires established by the Anglo-Saxons and others. They ceased to be used for administration with the creation of the administrative counties in 1889. They are alternatively known as ancient counties or traditional counties. Where they are not included among the modern counties of England they are also known as former counties. Despite this name, several historic counties continue to be recognised as cultural regions and have their own county days, county flags and boundary signs, many of which were created or registered long after these counties were abandoned as units for administrative purposes.  - A national mapping agency is an organisation, usually publicly owned, that produces topographic maps and geographic information of a country. Some national mapping agencies also deal with cadastral matters.  - A shire is a traditional term for a division of land, found in the United Kingdom and Australia. It was first used in Wessex from the beginning of Anglo-Saxon settlement, and spread to most of the rest of England in the tenth century.
