Hasan Bin Sabbah
Hasan al-Sabbah also known as Hasan I of Alamut, was an Iranian religious and military leader, founder of the Nizari Ismai'li sect widely known as the ''Hashshashin'' or the Order of Assassins, as well as the Nizari Ismaili state, ruling from 1090 to 1124 AD.Lewis, Bernard (1967), ''The Assassins: a Radical Sect of Islam'', pp 38-65, Oxford University Press Alongside his role as a formidable leader, Sabbah was an accomplished scholar of mathematics, most notably in geometry, as well as astronomy and philosophy, especially in epistemology. E. G. Brown ''Literary History of Persia'', Vol. 1, p. 201. Nizam al-Mulk Tusi, pg. 420, foot note No. 3 It is narrated that Hasan and the Persian polymath Omar Khayyam were close friends since their student years. He and each of the later Assassin leaders came to be known in the West as the Old Man of the Mountain, a name given to the sect's leader in the writings of Marco Polo that referenced the sect's possession of the commanding mountain ...

Nizārī Ismā'īlī State
The Nizari state (the Alamut state) was a Nizari Isma'ili Shia state founded by Hassan-i Sabbah after he took control of the Alamut Castle in 1090 AD, which marked the beginning of an era of Ismailism known as the "Alamut period". Their people were also known as the '' Assassins'' or ''Hashashins''. The state consisted of a nexus of strongholds throughout Persia and the Levant, with their territories being surrounded by huge swathes of hostile as well as crusader territory. It was formed as a result of a religious and political movement of the minority Nizari sect supported by the anti- Seljuk population. Being heavily outnumbered, the Nizaris resisted adversaries by employing strategic, self-sufficient fortresses and the use of unconventional tactics, notably assassination of important adversaries and psychological warfare. They also had a strong sense of community as well as total obedience to their leader. Despite being occupied with survival in their hostile environment ...

Sharia
Sharia, Sharī'ah, Shari'a, or Shariah () is a body of religious law that forms a part of the Islamic tradition based on Islamic holy books, scriptures of Islam, particularly the Quran, Qur'an and hadith. In Islamic terminology ''sharīʿah'' refers to immutable, intangible divine law; contrary to ''fiqh'', which refers to its interpretations by Ulama, Islamic scholars. Sharia, or fiqh as traditionally known, has always been used alongside urf, customary law from the very beginning in Islamic history; has been elaborated and developed over the centuries by fatwa, legal opinions issued by mufti, qualified jurists – reflecting the tendencies of Schools of Fiqh, different schools – and integrated and with various economic, penal and administrative laws issued by Muslims, Muslim rulers; and implemented for centuries by Qadi, judges in the courts until recent times, when secularism was widely adopted in Islamic societies. Traditional Principles of Islamic jurisprudence, theory o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epistemology
Epistemology is the branch of philosophy that examines the nature, origin, and limits of knowledge. Also called "the theory of knowledge", it explores different types of knowledge, such as propositional knowledge about facts, practical knowledge in the form of skills, and knowledge by acquaintance as a familiarity through experience. Epistemologists study the concepts of belief, truth, and justification to understand the nature of knowledge. To discover how knowledge arises, they investigate sources of justification, such as perception, introspection, memory, reason, and testimony. The school of skepticism questions the human ability to attain knowledge while fallibilism says that knowledge is never certain. Empiricists hold that all knowledge comes from sense experience, whereas rationalists believe that some knowledge does not depend on it. Coherentists argue that a belief is justified if it coheres with other beliefs. Foundationalists, by contrast, maintain th ...

Philosophy
Philosophy ('love of wisdom' in Ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, Value (ethics and social sciences), value, mind, and language. It is a rational and critical inquiry that reflects on its methods and assumptions. Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western philosophy, Western, Islamic philosophy, Arabic–Persian, Indian philosophy, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the Spirituality, spiritual problem of how to reach Enlightenment in Buddhism, enlighten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, M ...

Geometry
Geometry (; ) is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a ''List of geometers, geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point (geometry), point, line (geometry), line, plane (geometry), plane, distance, angle, surface (mathematics), surface, and curve, as fundamental concepts. Originally developed to model the physical world, geometry has applications in almost all sciences, and also in art, architecture, and other activities that are related to graphics. Geometry also has applications in areas of mathematics that are apparently unrelated. For example, methods of algebraic geometry are fundamental in Wiles's proof of Fermat's Last Theorem, Wiles's proof of Fermat's ...

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Hashshashin
The Order of Assassins (; ) were a Nizari Isma'ili order that existed between 1090 and 1275 AD, founded by Hasan al-Sabbah. During that time, they lived in the mountains of Persia and the Levant, and held a strict subterfuge policy throughout the Middle East, posing a substantial strategic threat to Fatimid, Abbasid, and Seljuk authority, and killing several Christian leaders. Over the course of nearly 200 years, they killed hundreds who were considered enemies of the Nizari Isma'ili state. The modern term assassination is believed to stem from the tactics used by the Assassins. Contemporaneous historians include ibn al-Qalanisi, Ali ibn al-Athir, and Ata-Malik Juvayni. The former two referred to the Assassins as '' batiniyya'', an epithet widely accepted by Isma'ilis themselves. Overview The Assassins were founded by Hassan-i Sabbah. The state was formed in 1090 after the capture of Alamut Castle in the Alborz mountain range of Persia, which served as the Assassins' ...

Nizari Ismai'li
Nizari Isma'ilism () are the largest segment of the Ismailis, who are the second-largest branch of Shia Islam after the Twelvers. Nizari teachings emphasise independent reasoning or ''ijtihad''; pluralism—the acceptance of racial, ethnic, cultural and inter-religious differences; and social justice. Nizaris, along with Twelvers, adhere to the Jaʽfari school of jurisprudence. The Aga Khan, currently Aga Khan V, is the spiritual leader and Imam of the Nizaris. The global seat of the Ismaili Imamate is in Lisbon, Portugal. Early history Nizari Isma'ili history is often traced through the unbroken hereditary chain of guardianship, or ''walayah'', beginning with Ali Ibn Abi Talib, whom Shias believe the prophet Muhammad declared his successor as Imam during the latter's final pilgrimage to Mecca, and continued in an unbroken chain to the most recent Imam, Shah Rahim Al-Husayni, the Aga Khan.
