Baghdad in the context of "House of Wisdom"

Iraq, officially the Republic of Iraq, is a country in West Asia. Located within the geo-political region of the Middle East, it is bordered by Saudi Arabia to the south, Turkey to the north, Iran to the east, the Persian Gulf and Kuwait to the southeast, Jordan to the southwest, and Syria to the west. The country covers an area of 438,317 square kilometres (169,235 sq mi) and has a population of over 46 million, making it the 58th largest country by area and the 31st most populous in the world. Baghdad, home to over 8 million people, is the capital city and the largest in the country.

Starting in the 6th millennium BC, the fertile plains between Iraq's Tigris and Euphrates rivers, referred to as Mesopotamia, fostered the rise of early cities, civilisations, and empires including Sumer, Akkad, Babylonia, and Assyria. Known as the cradle of civilisation, Mesopotamia saw the invention of writing systems, mathematics, navigation, timekeeping, a calendar, astrology, the wheel, the sailboat, and a law code. After the Muslim conquest of Mesopotamia, Baghdad became the capital of the Abbasid Caliphate and a global cultural and intellectual hub during the Islamic Golden Age, home to institutions such as the House of Wisdom. Following Baghdad's destruction by the Mongols in 1258, Iraq came under successive empires and, from the 16th century until the 20th century, was governed within the Ottoman system as a defined region known administratively as ‘the Iraq Region’. Additionally, Iraq holds religious significance in Christianity, Judaism, Yazidism, and Mandaeism.

The Islamic Golden Age was a period of scientific, economic, and cultural flourishing in the history of Islam, traditionally dated from the 8th century to the 13th century.

This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom, which saw scholars from all over the Muslim world flock to Baghdad, the world's largest city at the time, to translate the known world's classical knowledge into Arabic and Persian. The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the siege of Baghdad in 1258.

Lama, Lamma, or Lamassu (Cuneiform: 𒀭𒆗, an.kal; Sumerian: lammař; later in Akkadian: lamassu; sometimes called a lamassuse) is a Mesopotamian protective deity.

Initially depicted as a goddess in Sumerian times, when it was called Lamma, it was later depicted from Assyrian times as a hybrid of a human, bird, and either a bull or lion—specifically having a human head, the body of a bull or a lion, and bird wings, under the name Lamassu. In some writings, it is portrayed to represent a goddess. A less frequently used name is shedu (Cuneiform: 𒀭𒆘, an.kal×bad; Sumerian: alad; Akkadian, šēdu), which refers to the male counterpart of a lamassu. Lamassu represent the zodiacs, parent-stars or constellations.

Abū Yūsuf Yaʻqūb ibn ʼIsḥāq aṣ-Ṣabbāḥ al-Kindī (/ælˈkɪndi/; Arabic: أبو يوسف يعقوب بن إسحاق الصبّاح الكندي; Latin: Alkindus; c. 801–873 AD) was an Arab Muslim polymath active as a philosopher, mathematician, physician, and music theorist. Al-Kindi was the first of the Islamic peripatetic philosophers, and is hailed as the "father of Arab philosophy".

Al-Kindi was born in Kufa and educated in Baghdad. He became a prominent figure in the House of Wisdom, and a number of Abbasid Caliphs appointed him to oversee the translation of Greek scientific and philosophical texts into the Arabic language. This contact with "the philosophy of the ancients" (as Hellenistic philosophy was often referred to by Muslim scholars) had a profound effect on him, as he synthesized, adapted and promoted Hellenistic and Peripatetic philosophy in the Muslim world. He subsequently wrote hundreds of original treatises of his own on a range of subjects ranging from metaphysics, ethics, logic and psychology, to medicine, pharmacology, mathematics, astronomy, astrology and optics, and further afield to more practical topics like perfumes, swords, jewels, glass, dyes, zoology, tides, mirrors, meteorology and earthquakes.

The Kish tablet is a limestone tablet found at the site of the ancient Sumerian city of Kish in modern Tell al-Uhaymir, Babylon Governorate, Iraq. A plaster cast of the tablet is in the collection of the Ashmolean Museum, while the original is housed at the Iraq Museum in Baghdad. It should not be confused with the Scheil dynastic tablet, which contains part of the Sumerian King List and is also sometimes called the Kish tablet.

The signs on the Kish tablet, possibly related to proto-cuneiform, are purely pictographic, and have not been deciphered or demonstrated to correspond to any currently known human language. It has been dated to the Late Uruk period (c. 3200–3000 BC).

The Parthian Empire (/ˈpɑːrθiən/), also known as the Arsacid Empire (/ˈɑːrsəsɪd/), was a major Iranian political and cultural power centered in ancient Iran from 247 BC to 224 AD. Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (r. c. 171 – 132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to present-day Afghanistan and western Pakistan. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han dynasty of China, became a center of trade and commerce.

The Parthians largely adopted the art, architecture, religious beliefs, and regalia of their culturally heterogeneous empire, which encompassed Persian, Hellenistic, and regional cultures. For about the first half of its existence, the Arsacid court adopted elements of Greek culture, though it eventually saw a gradual revival of Iranian traditions. The Arsacid rulers were titled "King of Kings", claiming inheritance of the Achaemenid Empire; indeed, they accepted many local kings as vassals, although the Achaemenids would have had centrally appointed, albeit largely autonomous, satraps. The court did appoint a small number of satraps, largely outside Iran, but these satrapies were smaller and less powerful than the Achaemenid potentates. With the expansion of Arsacid power, the seat of central government shifted from Nisa to Ctesiphon along the Tigris (south of Baghdad), although several other sites also served as capitals.

The Mongol conquest of Persia and Mesopotamia comprised three Mongol campaigns against Islamic states in the Middle East and Central Asia between 1219 and 1258. These campaigns led to the termination of the Khwarazmian Empire, the Nizari Ismaili state, and the Abbasid Caliphate of Baghdad, and the establishment of the Mongol Ilkhanate government in their place in Persia.

Genghis Khan had unified the Mongolic peoples and conquered the Western Xia state in the late 12th and early 13th centuries. After a series of diplomatic provocations on the part of Muhammad II, the ruler of the neighbouring Khwarazmian Empire, the Mongols launched an invasion in 1219. The invaders laid waste to the Transoxianan cities of Bukhara, Samarkand, and Gurganj in turn, before obliterating the region of Khorasan, slaughtering the inhabitants of Herat, Nishapur, and Merv, three of the largest cities in the world. Muhammad died destitute on an island in the Caspian Sea. His son and successor, Jalal al-Din, tried to resist the Mongols, but was defeated and forced into exile. Genghis returned to his campaign against the Jin dynasty in 1223, only retaining governance of the northern Khwarazmian regions.

The Tigris (/ˈtaɪɡrɪs/ TY-griss; see below) is the eastern of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, before merging with the Euphrates and reaching to the Persian Gulf.

The Tigris passes through historical cities like Mosul, Tikrit, Samarra, and Baghdad. It is also home to archaeological sites and ancient religious communities, including the Mandaeans, who use it for baptism. In ancient times, the Tigris nurtured the Assyrian Empire, with remnants like the relief of King Tiglath-Pileser.

The Abbasid Caliphate or Abbasid Empire was the third Islamic caliphate, founded by a descendant of Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty derives its name. The preceding Umayyad Caliphate was overthrown by the Abbasid Revolution in 750 CE (132 AH), after which the Abbasids ruled as caliphs from their base in Iraq, with Baghdad as their capital for most of their history.

The Abbasid Revolution had its origins and first successes in the easterly region of Khurasan, far from the Levantine center of Umayyad influence. The Abbasids first centered their government in Kufa, Iraq, but in 762 the second caliph al-Mansur founded the city of Baghdad and made it the capital. Baghdad became a center of science, culture, arts, and invention, ushering in what became known as the Golden Age of Islam. Baghdad housed several key academic institutions, such as the House of Wisdom, and along with its multi-ethnic and multi-religious population, made the city famous as a centre of learning across the world. The Abbasid period was marked by the use of bureaucrats in the government, including the vizier, as well as an in the ummah (Muslim community) and among the political elites.
