Sumer in the context of Civilizing

A civilization (also spelled civilisation in British English) is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems).

Civilizations are organized around densely populated settlements, divided into more or less rigid hierarchical social classes of division of labour, often with a ruling elite and subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over the rest of nature, including over other human beings. Civilizations are characterized by elaborate agriculture, architecture, infrastructure, technological advancement, currency, taxation, regulation, and specialization of labour.

The 4th millennium BC spanned the years 4000 BC to 3001 BC. Some of the major changes in human culture during this time included the beginning of the Bronze Age and the invention of writing, which played a major role in starting recorded history.

The city states of Sumer and the (Predynastic) Kingdom of Egypt were established and grew to prominence. Agriculture spread widely across Eurasia.

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 ancient Near East was home to many cradles of civilization, spanning Mesopotamia, the Levant,, Egypt, Iran, Anatolia and the Armenian highlands, and the Arabian Peninsula. As such, the fields of ancient Near East studies and Near Eastern archaeology are one of the most prominent with regard to research in the realm of ancient history. Historically, the Near East denoted an area roughly encompassing the centre of West Asia, having been focused on the lands between Greece and Egypt in the west and Iran in the east. It therefore largely corresponds with the modern-day geopolitical concept of the Middle East.

The history of the ancient Near East begins with the rise of Sumer in the 4th millennium BC, though the date that it ends is a subject of debate among scholars; the term covers the region's developments in the Bronze Age and the Iron Age, and is variously considered to end with either the establishment of the Achaemenid Empire in the 6th century BC, the establishment of the Macedonian Empire in the 4th century BC, or the beginning of the early Muslim conquests in the 7th century AD.

The Fertile Crescent (Arabic: الهلال الخصيب al-hilāl al-ḵaṣīb) is a crescent-shaped region in the Middle East, spanning modern-day Iraq, Israel, Jordan, Lebanon, Palestine, and Syria, together with northern Kuwait, south-eastern Turkey, and western Iran. Some authors also include Cyprus and northern Egypt.

The Fertile Crescent is believed to be the first region where settled farming emerged as people started the process of clearance and modification of natural vegetation to grow newly domesticated plants as crops. Early human civilizations such as Sumer in Mesopotamia flourished as a result. Technological advances in the region include the development of agriculture and the use of irrigation, of writing, the wheel, and glass, most emerging first in Mesopotamia.

The Middle East, or the Near East, was one of the cradles of civilization: after the Neolithic Revolution and the adoption of agriculture, many of the world's oldest cultures and civilizations were created there. Since ancient times, the Middle East has had several lingua franca: Akkadian, Hebrew, Aramaic, Greek, and Arabic. The Sumerians, around the 5th millennium BC, were among the first to develop a civilization. By 3150 BC, Egyptian civilization unified under its first pharaoh. Mesopotamia hosted powerful empires, notably Assyria which lasted for 1,500 years. For centuries after the 7th century BC, the region was dominated by Persian powers like the Achaemenid Empire.

In the 1st century BC, the Roman Republic conquered most of the region, and its successor, the Roman Empire, that ruled from the 6th to 15th centuries AD referred to as the Byzantine Empire, grew significantly more. Roman pagan religions were replaced by Christianity in the 4th century AD. From the 3rd to 7th centuries, Rome ruled alongside the Sasanian Empire. From the 7th century, Islam spread rapidly, expanding Arab identity in the region. The Seljuk dynasty displaced Arab dominance in the 11th century, followed by the Mongol Empire in the 13th century.

Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins c. 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared c. 5,200 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory has not been completely discarded.

In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and keep historical records, with their neighbours following. Most other civilizations reached their end of prehistory during the following Iron Age. The three-age division of prehistory into Stone Age, Bronze Age, and Iron Age remains in use for much of Eurasia and North Africa, but is not generally used in those parts of the world where the working of hard metals arrived abruptly from contact with Eurasian cultures, such as Oceania, Australasia, much of Sub-Saharan Africa, and parts of the Americas. With some exceptions in pre-Columbian civilizations in the Americas, these areas did not develop writing systems before the arrival of Eurasians, so their prehistory reaches into relatively recent periods; for example, 1788 is usually taken as the end of the prehistory of Australia.

Sumerian (Sumerian: 𒅴𒂠, romanized: eme-gir₁₅, lit. ''native language'') was the language of ancient Sumer. It is one of the oldest attested languages, dating back to at least 2900 BC. It is a local language isolate that was spoken in ancient Mesopotamia, in the area that is now modern-day Iraq.

Sumerian is read from left to right, from the top, however early inscriptions were read top to bottom from the right.

Mesoamerica is a historical region and cultural area comprising the present day lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, western Honduras, and the Greater Nicoya region of Nicaragua and Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures.

In the pre-Columbian era, many indigenous societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas began on Hispaniola in 1493. In world history, Mesoamerica was the site of two historical transformations: (i) primary urban generation, and (ii) the formation of New World cultures from the mixtures of the indigenous Mesoamerican peoples with the European, African, and Asian peoples who were introduced by the Spanish colonization of the Americas. Mesoamerica is one of the six areas in the world where ancient civilization arose independently (see cradle of civilization), and the second in the Americas, alongside the Caral–Supe in present-day Peru. Mesoamerica is also one of only five regions of the world where writing is known to have independently developed (the others being ancient Egypt, India, Sumer, and China).

Ur (/ʊr/ or /ɜːr/) was a major Sumerian city-state in ancient Mesopotamia, located at the site of modern Tell el-Muqayyar (Arabic: تَلّ ٱلْمُقَيَّر, lit. 'mound of bitumen') in Dhi Qar Governorate, southern Iraq. Although Ur was a coastal city near the mouth of the Euphrates on the Persian Gulf, the coastline has shifted and the site is now well inland, on the south bank of the Euphrates, 16 km (10 mi) southwest of Nasiriyah in modern-day Iraq. The city dates from the Ubaid period c. 3800 BC, and is recorded in written history as a city-state from the 26th century BC, its first recorded king being Mesannepada.

The city's patron deity was the moon god Nanna (Sin in Akkadian), and the name of the city is derived from UNUG, literally "the abode (of Nanna)". The site is marked by the partially restored ruins of the Ziggurat of Ur, which contained the shrine of Nanna, excavated in the 1930s. The temple was built in the 21st century BC (short chronology), during the reign of Ur-Nammu and was reconstructed in the 6th century BC by Nabonidus, the last king of Babylon.

The division of labour is the separation of the tasks in any economic system or organisation so that participants may specialise (specialisation). Individuals, organisations, and nations are endowed with or acquire specialised capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialised capabilities may include equipment or natural resources as well as skills. Training and combinations of equipment and other assets acting together are often important. For example, an individual may specialise by acquiring tools and the skills to use them effectively just as an organisation may specialise by acquiring specialised equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence.

An increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of industrialised processes. The concept and implementation of division of labour has been observed in ancient Sumerian (Mesopotamian) culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence. Division of labour generally also increases both producer and individual worker productivity.

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.

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 Chalcolithic or Copper Age is the transitional period between the Neolithic and the Bronze Age. It is taken to begin around the mid-5th millennium BC, and ends with the beginning of the Bronze Age proper, in the late 4th to 3rd millennium BC, depending on the region.

The Chalcolithic is part of prehistory, but based on archaeological evidence, the emergence of the first state societies can be inferred, notably in the Fertile Crescent (notably Sumer) Predynastic Egypt, and Proto-Minoan Crete, with late Neolithic societies of comparable complexity emerging in the Indus Valley (Mehrgarh), China, and along the north-western shores of the Black Sea.

The first evidence of horses in warfare dates from Eurasia between 4000 and 3000 BC. A Sumerian illustration of warfare from 2500 BC depicts some type of equine pulling wagons. By 1600 BC, improved harness and chariot designs made chariot warfare common throughout the Ancient Near East, and the earliest written training manual for war horses was a guide for training chariot horses written about 1350 BC. As formal cavalry tactics replaced the chariot, so did new training methods, and by 360 BC, the Greek cavalry officer Xenophon had written an extensive treatise on horsemanship. The effectiveness of horses in battle was also revolutionized by improvements in technology, such as the invention of the saddle, the stirrup, and the horse collar.

Many different types and sizes of horses were used in war, depending on the form of warfare. The type used varied with whether the horse was being ridden or driven, and whether they were being used for reconnaissance, cavalry charges, raiding, communication, or supply. Throughout history, mules and donkeys, as well as horses played a crucial role in providing support to armies in the field.

The Akkadian Empire (/əˈkeɪdiən/) or kingdom of Akkad/Agade was an ancient kingdom, often thought to be the first known empire, succeeding the long-lived city-states of Sumer. Centered on the city of Akkad (/ˈækæd/ or /ˈɑːkɑːd/) and its surrounding region in modern-day Iraq, the empire united the Semitic Akkadian and Sumerian speakers under one rule and exercised significant influence across Mesopotamia, the Levant, modern-day Iran and Anatolia, sending military expeditions as far south as Dilmun and Magan (modern United Arab Emirates, Saudi Arabia, Bahrain, Kuwait, Qatar and Oman) in the Arabian Peninsula.

Established by Sargon of Akkad after defeating the Sumerian king Lugal-zage-si, it replaced the system of independent Sumero-Akkadian city-states and unified a vast region, stretching from the Mediterranean to Iran and from Anatolia to the Persian Gulf, under a centralized government. Sargon and his successors, especially his grandson Naram-Sin, expanded the empire through military conquest, administrative reforms, and cultural integration. Naram-Sin took the unprecedented step of declaring himself a living god and adopted the title "King of the Four Quarters." The Semitic Akkadian language became the empire’s lingua franca, although Sumerian (a language isolate) remained important in religion and literature. The empire was documented through inscriptions, administrative tablets, and seals, including notable sources like the Bassetki Statue. Enheduanna, Sargon’s daughter, served as high priestess and is recognized as the first known named author in history.

The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past. Before the modern age and worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad and Assyria, followed closely by Ancient Egypt and the Levantine state of Ebla began using arithmetic, algebra and geometry for taxation, commerce, trade, and in astronomy, to record time and formulate calendars.

The earliest mathematical texts available are from Mesopotamia and Egypt – Plimpton 322 (Babylonian c. 2000 – 1900 BC), the Rhind Mathematical Papyrus (Egyptian c. 1800 BC) and the Moscow Mathematical Papyrus (Egyptian c. 1890 BC). All these texts mention the so-called Pythagorean triples, so, by inference, the Pythagorean theorem seems to be the most ancient and widespread mathematical development, after basic arithmetic and geometry.
