The term is used by modern historians for the former Islamic states in modern Spain and Portugal. At its greatest geographical extent, it occupied most of the peninsula and a part of present-day southern France, Septimania (8th century). For nearly a hundred years, from the 9th century to the 10th, al-Andalus extended its presence from Fraxinetum into the Alps with a series of organized raids and chronic banditry. The name describes the different Arab and Muslim states that controlled these territories at various times between 711 and 1492.

Arab
The Arabs (singular: Arab; singular ar, عَرَبِيٌّ, DIN 31635: , , plural ar, عَرَب, DIN 31635: , Arabic pronunciation: ), also known as the Arab people, are an ethnic group mainly inhabiting the Arab world in Western Asia, North Africa, the Horn of Africa, and the western Indian Ocean islands (including the Comoros). An Arab diaspora is also present around the world in significant numbers, most notably in the Americas, Western Europe, Turkey, Indonesia, and Iran. In modern usage, the term "Arab" tends to refer to those who both carry that ethnic identity and speak Arabic as their native language. This contrasts with the narrower traditional definition, which refers to the descendants of the tribes of Arabia. The religion of Islam was developed in Arabia, and Classical Arabic serves as the language of Islamic literature. 93 percent of Arabs are Muslims (the remainder consisted mostly of Arab Christians), while Arab Muslims are only 20 percent of the ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

15th-century Arabs
The 15th century was the century which spans the Julian dates from 1 January 1401 ( MCDI) to 31 December 1500 ( MD). In Europe, the 15th century includes parts of the Late Middle Ages, the Early Renaissance, and the early modern period. Many technological, social and cultural developments of the 15th century can in retrospect be seen as heralding the "European miracle" of the following centuries. The architectural perspective, and the modern fields which are known today as banking and accounting were founded in Italy. The Hundred Years' War ended with a decisive French victory over the English in the Battle of Castillon. Financial troubles in England following the conflict resulted in the Wars of the Roses, a series of dynastic wars for the throne of England. The conflicts ended with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the later part of the century.

Medieval Syrian Mathematicians
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
14th-century Mathematicians
As a means of recording the passage of time, the 14th century was a century lasting from 1 January 1301 ( MCCCI), to 31 December 1400 ( MCD). It is estimated that the century witnessed the death of more than 45 million lives from political and natural disasters in both Europe and the Mongol Empire. West Africa experienced economic growth and prosperity. In Europe, the Black Death claimed 25 million lives wiping out one third of the European population while the Kingdom of England and the Kingdom of France fought in the protracted Hundred Years' War after the death of Charles IV, King of France led to a claim to the French throne by Edward III, King of England. This period is considered the height of chivalry and marks the beginning of strong separate identities for both England and France as well as the foundation of the Italian Renaissance and Ottoman Empire.
