Mamluk Sultanate
The Mamluk Sultanate (), also known as Mamluk Egypt or the Mamluk Empire, was a state that ruled Egypt, the Levant and the Hejaz from the mid-13th to early 16th centuries, with Cairo as its capital. It was ruled by a military caste of mamluks (freed slave soldiers) headed by a sultan. The sultanate was established with the overthrow of the Ayyubid dynasty in Egypt in 1250 and was conquered by the Ottoman Empire in 1517. Mamluk history is generally divided into the Turkic or Bahri period (1250–1382) and the Circassian or Burji period (1382–1517), called after the predominant ethnicity or corps of the ruling Mamluks during these respective eras. The first rulers of the sultanate hailed from the mamluk regiments of the Ayyubid sultan as-Salih Ayyub (), usurping power from his successor in 1250. The Mamluks under Sultan Qutuz and Baybars routed the Mongols in 1260, halting their southward expansion. They then conquered or gained suzerainty over the Ayyubids' Syrian p ...

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, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); 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's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number".

15th-century Arab People
The 15th century was the century which spans the Julian calendar dates from 1 January 1401 (represented by the Roman numerals 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. Constantin ...

Medieval Syrian Mathematicians
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of World history (field), 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 Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised 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 ...

14th-century Mathematicians
The 14th century lasted from 1 January 1301 (represented by the Roman numerals 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 King Charles IV of France led to a claim to the French throne by King Edward III 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 the Ottoman Empire. In Asia, Tamerlane (Timur), established the Timurid Empire, history's third largest empire to have been ever established by a single conqueror. ...
