The History Portal
(c. 484 BC – c. 425 BC), often considered the "father of history"
History (from Greek ?στορ?α, historia, meaning 'inquiry; knowledge acquired by investigation') is the past as it is described in written documents, and the study thereof. Events occurring before written records are considered prehistory. "History" is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians.
History also includes the academic discipline which uses a narrative to examine and analyse a sequence of past events, and objectively determine the patterns of cause and effect that determine them. Historians sometimes debate the nature of history and its usefulness by discussing the study of the discipline as an end in itself and as a way of providing "perspective" on the problems of the present.
Stories common to a particular culture, but not supported by external sources (such as the tales surrounding King Arthur), are usually classified as cultural heritage or legends, because they do not show the "disinterested investigation" required of the discipline of history. Herodotus, a 5th-century BC Greek historian is considered within the Western tradition to be the "father of history", and, along with his contemporary Thucydides, helped form the foundations for the modern study of human history. Their works continue to be read today, and the gap between the culture-focused Herodotus and the military-focused Thucydides remains a point of contention or approach in modern historical writing. In East Asia, a state chronicle, the Spring and Autumn Annals, was known to be compiled from as early as 722 BC although only 2nd-century BC texts have survived.
Ancient influences have helped spawn variant interpretations of the nature of history which have evolved over the centuries and continue to change today. The modern study of history is wide-ranging, and includes the study of specific regions and the study of certain topical or thematical elements of historical investigation. Often history is taught as part of primary and secondary education, and the academic study of history is a major discipline in university studies.
The Treaty of Devol
: συνθ?κη τη? Δεαβ?λεω?
) was an agreement made in 1108 between Bohemond I
and Byzantine Emperor Alexios I Komnenos
, in the wake of the First Crusade
. It is named after the Byzantine fortress of Devol
(in modern Albania
). Although the treaty was not immediately enforced, it was intended to make the Principality of Antioch
state of the Byzantine Empire
At the beginning of the First Crusade, Crusader armies assembled at Constantinople and promised to return to the Byzantine Empire any land they might conquer. However, Bohemond, the son of Alexios' former enemy Robert Guiscard, claimed the Principality of Antioch for himself. Alexios did not recognize the legitimacy of the Principality, and Bohemond went to Europe looking for reinforcements. He launched into open warfare against Alexios, but he was soon forced to surrender and negotiate with Alexios at the imperial camp at Diabolis (Devol), where the Treaty was signed.
Under the terms of the Treaty, Bohemond agreed to become a vassal of the Emperor and to defend the Empire whenever needed. He also accepted the appointment of a Greek Patriarch. In return, he was given the titles of sebastos and doux (duke) of Antioch, and he was guaranteed the right to pass on to his heirs the County of Edessa. Following this, Bohemond retreated to Apulia and died there. His nephew, Tancred, who was regent in Antioch, refused to accept the terms of the Treaty. Antioch came temporarily under Byzantine sway in 1137, but it was not until 1158 that it truly became a Byzantine vassal.
: Shěn Kuò
: Shen K'uo
) (1031–1095), style name Cunzhong
(存中) and pseudonym Mengqi
(now usually given as Mengxi
(夢溪翁), was a polymathic Chinese scientist
and statesman of the Song Dynasty
(960–1279). Excelling in many fields of study and statecraft, he was a mathematician
, hydraulic engineer
, academy chancellor
, finance minister
, governmental state inspector, poet
, and musician
. He was the head official for the Bureau of Astronomy
in the Song court, as well as an Assistant Minister of Imperial Hospitality. At court his political allegiance was to the Reformist faction known as the New Policies Group
, headed by Chancellor Wang Anshi
In his Dream Pool Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the polestar and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancer compasses in regards to declination).

The Khoikhoi were a historical group of Khoisan people, native to southwest Africa. The Khokhois had settled the region in the 5th century AD, and when Europeans first arrived there in 1652, they were still practicing traditional pastoral agriculture. Here, they are dismantling their huts in preparation for moving to more fertile grazing grounds.

What transforms this world is — knowledge. Do you see what I mean? Nothing else can change anything in this world.
