Query: When did Mitanni exist?
Mitanni was an Indo-Iranian empire in northern Mesopotamia from c. 1500 BC. At the height of Mitanni power, during the 14th century BC, it encompassed what is today southeastern Turkey, northern Syria and northern Iraq, centered around its capital, Washukanni, whose precise location has not been determined by archaeologists.
Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the northern reaches of the Nile River in Egypt. The civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next three millennia. Its history occurred in a series of stable "kingdoms", separated by periods of relative instability known as "intermediate periods". Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in the late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province. Although the Egyptian military forces in the Old and Middle kingdoms were well maintained, the new form that emerged in the New Kingdom showed the state becoming more organized to serve its needs.
The earliest known Ugarit contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BC. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit BC written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BC, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya).
Ancient Egypt developed over at least three and a half millennia. It began with the incipient unification of Nile Valley polities around 3500 BC and is conventionally thought to have ended in 30 BC when the early Roman Empire conquered and absorbed Ptolemaic Egypt as a province. (Though this last did not represent the first period of foreign domination, the Roman period was to witness a marked, if gradual transformation in the political and religious life of the Nile Valley, effectively marking the termination of independent civilisational development).
The historical records of ancient Egypt begin with Egypt as a unified state, which occurred sometime around 3150 BC. According to Egyptian tradition, Menes, thought to have unified Upper and Lower Egypt, was the first king. This Egyptian culture, customs, art expression, architecture, and social structure was closely tied to religion, remarkably stable, and changed little over a period of nearly 3000 years.
In Ancient Egypt the Bronze Age begins in the Protodynastic period, BC. The archaic "early Bronze Age of Egypt", known as the Early Dynastic Period of Egypt, immediately follows the unification of Lower and Upper Egypt, BC. It is generally taken to include the First and Second Dynasties, lasting from the Protodynastic Period of Egypt until about 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king. Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilization, such as art, architecture and many aspects of religion, took shape during the Early Dynastic period. Memphis in the Early Bronze Age was the largest city of the time.
The Old Kingdom of the regional Bronze Age is the name given to the period in the 3rd millennium BC when Egypt attained its first continuous peak of civilization in complexity and achievement – the first of three "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley (the others being Middle Kingdom and the New Kingdom).
Ancient Egypt was one of the world's first civilizations, with its beginnings in the fertile Nile valley around 3150 BC. Ancient Egypt reached the zenith of its power during the New Kingdom (1570–1070 BC) under great pharaohs. Ancient Egypt was a great power to be contended with by both the ancient Near East, the Mediterranean and sub-Saharan Africa. The empire expanded far south into Nubia and held wide territories across the ancient Near East. The combination of a fertile river valley, natural borders that made an invasion unfeasible, and a military able to rise to the challenge when needed, turned Egypt into a major power. It was one of the first nations to have a system of writing and large scale construction projects. However, as neighboring civilizations developed militaries capable of crossing Egypt's natural barriers, the Egyptian armies were not always able to repel them and so by 1000 BC Egyptian influence as an independent civilization waned.
After the fall of Dʿmt during the fourth century BC, the Ethiopian plateau came to be dominated by smaller successor kingdoms. In the first century AD, the Kingdom of Aksum emerged in what is now Tigray and Eritrea. According to the medieval "Book of Aksum", the kingdom's first capital, Mazaber, was built by Itiyopis, son of Cush. Aksum would later at times extend its rule into Yemen on the other side of the Red Sea. The Persian religious figure Mani listed Aksum with Rome, Persia, and China as one of the four great powers of his era, during the 3rd century.
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
The Kingdom of Aksum (also known as the Kingdom of Axum, or the Aksumite Empire) was an ancient kingdom located in what is now Tigray Region (northern Ethiopia) and Eritrea.. Axumite Emperors were powerful sovereigns, styling themselves King of kings, king of Aksum, Himyar, Raydan, Saba, Salhen, Tsiyamo, Beja and of Kush.
Ruled by the Aksumites, it existed from approximately 100 AD to 940 AD. The polity was centered in the city of Axum and grew from the proto-Aksumite Iron Age period around the 4th century BC to achieve prominence by the 1st century AD. 
Aksum became a major player on the commercial route between the Roman Empire and Ancient India. The Aksumite rulers facilitated trade by minting their own Aksumite currency, with the state establishing its hegemony over the declining Kingdom of Kush. It also regularly entered the politics of the kingdoms on the Arabian Peninsula and eventually extended its rule over the region with the conquest of the Himyarite Kingdom. The Manichaei prophet Mani (died 274 AD) regarded Axum as one of the four great powers of his time, the others being Persia, Rome, and China.
Soon after the Sumerian civilization began, the Nile valley of Lower and Upper Egypt was unified under the Pharaohs approximately around 3150 BC. Since then, Ancient Egypt experienced 3 high points of civilization, the so-called "Kingdom" periods:
The history of Ancient Egypt is concluded by the Late Period (664–332 BC), immediately followed by the history of Egypt in Classical Antiquity, beginning with Ptolemaic Egypt.
The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age of the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BC with earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion.
The Kingdom of Aksum may have been founded as early as 300 BCE. Very little is known of the time period between the mid-1st millennium BCE to the beginning of Aksum's rise around the 1st century CE. It is thought to be a successor kingdom of Dʿmt, a kingdom in the early 1st millennium BC most likely centered at nearby Yeha.
Sumer in Mesopotamia, the Indus valley civilization and ancient Egypt were the first civilizations to develop their own scripts, and to keep historical records; this took place already during the early Bronze Age. Neighboring civilizations were the first to follow. Most other civilizations reached the end of prehistory during the Iron Age. The three-age system of division of prehistory into the Stone Age, followed by the 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 with contact with Eurasian cultures, such as the Americas, Oceania, Australasia and much of Sub-Saharan Africa. These areas also, with some exceptions in Pre-Columbian civilizations in the Americas, did not develop complex writing systems before the arrival of Eurasians, and their prehistory reaches into relatively recent periods; for example 1788 is usually taken as the end of the prehistory of Australia.
The Ptolemaic Kingdom was founded in 305 BC by Ptolemy I Soter, a "diadochus" originally from Macedon in northern Greece who declared himself pharaoh of Egypt and created a powerful Macedonian Greek dynasty that ruled an area stretching from southern Syria to Cyrene and south to Nubia. Scholars also argue that the kingdom was founded in 304 BC because of different use of calendars: Ptolemy crowned himself in 304 BC on the ancient Egyptian calendar, but in 305 BC on the ancient Macedonian calendar; to resolve the issue, the year 305/4 was counted as the first year of Ptolemaic Kingdom in Demotic papyri.
The earliest "Proto-Sinaitic" inscriptions are mostly dated to between the mid-19th (early date) and the mid-16th (late date) century BC.
"The principal debate is between an early date, around 1850 BC, and a late date, around 1550 BC. The choice of one or the other date decides whether it is proto-Sinaitic or proto-Canaanite, and by extension locates the invention of the alphabet in Egypt or Canaan respectively."
The evolution of "Proto-Sinaitic" and the various "Proto-Canaanite" scripts during the Bronze Age is based on rather scant epigraphic evidence;
it is only with the Bronze Age collapse and the rise of new Semitic kingdoms in the Levant that "Proto-Canaanite" is clearly attested (Byblos inscriptions 10th – 8th century BC, Khirbet Qeiyafa inscription c. 10th century BC).
Board games have been played in most cultures and societies throughout history. A number of important historical sites, artifacts, and documents shed light on early board games such as Jiroft civilization gameboards in Iran. Senet, found in Predynastic and First Dynasty burials of Egypt, c. 3500 BC and 3100 BC respectively, is the oldest board game known to have existed. Senet was pictured in a fresco found in Merknera's tomb (3300–2700 BC). Also from predynastic Egypt is Mehen.
Writing systems were preceded by proto-writing, systems of ideographic and/or early mnemonic symbols. The best known examples are:The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BC with earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion.
Causes for the decline and ultimate abandonment of the site around 1450 have been suggested as due to a decline in trade compared to sites further north, the exhaustion of the gold mines, political instability and famine and water shortages induced by climatic change. The Mutapa state arose in the fifteenth century from the northward expansion of the Great Zimbabwe tradition, having been founded by Nyatsimba Mutota from Great Zimbabwe after he was sent to find new sources of salt in the north; (this supports the belief that Great Zimbabwe's decline was due to a shortage of resources). Great Zimbabwe also predates the Khami and Nyanga cultures.
Mehen also appears to have been played outside of Egypt. It appears alongside other boards displaying the game of senet at Bab 'edu Dhra and in Cyprus. In Cyprus, it sometimes appears on the opposite side of the same stone as senet, and those from Sotira "Kaminoudhia", dating to approximately 2250 BCE, are the oldest surviving double-sided boards known. Mehen survived in Cyprus longer than in Egypt, showing that the game was indigenized upon its adoption into the island's culture.
Evidence for more complex mathematics does not appear until around 3000 BC, when the Babylonians and Egyptians began using arithmetic, algebra and geometry for taxation and other financial calculations, for building and construction, and for astronomy. The most ancient mathematical texts from Mesopotamia and Egypt are from 2000–1800 BC. Many early texts mention Pythagorean triples and so, by inference, the Pythagorean theorem seems to be the most ancient and widespread mathematical development after basic arithmetic and geometry. It is in Babylonian mathematics that elementary arithmetic (addition, subtraction, multiplication and division) first appear in the archaeological record. The Babylonians also possessed a place-value system, and used a sexagesimal numeral system, still in use today for measuring angles and time.
Thutmose III again waged war in Mitanni in the 33rd year of his rule. The Egyptian army crossed the Euphrates at Carchemish and reached a town called Iryn (maybe present day Erin, 20 km northwest of Aleppo.) They sailed down the Euphrates to Emar (Meskene) and then returned home via Mitanni. A hunt for elephants at Lake Nija was important enough to be included in the annals. This was impressive PR, but did not lead to any permanent rule. Only the area at the middle Orontes and Phoenicia became part of Egyptian territory.
At the beginning of its history, Mitanni's major rival was Egypt under the Thutmosids. However, with the ascent of the Hittite Empire, Mitanni and Egypt struck an alliance to protect their mutual interests from the threat of Hittite domination. At the height of its power, during the 14th century BC, Mitanni had outposts centred on its capital, Washukanni, whose location has been determined by archaeologists to be on the headwaters of the Khabur River. The Mitanni dynasty ruled over the northern Euphrates-Tigris region between c. 1475 and c. 1275 BC. Eventually, Mitanni succumbed to Hittite and later Assyrian attacks and was reduced to the status of a province of the Middle Assyrian Empire.
The emergence of the Mitanni Empire in the 16th century BC did eventually lead to a short period of sporadic Mitannian-Hurrian domination in the latter half of the 15th century. The Indo-European-speaking Mitannians are thought to have conquered and formed the ruling class over the indigenous Hurrians of eastern Anatolia. The Hurrians spoke a language isolate, i.e. neither Semitic nor Indo-European.
Ashur-nadin-ahhe I (1450–1431 BC) was courted by the Egyptians, who were rivals of Mitanni, and attempting to gain a foothold in the Near East. Amenhotep II sent the Assyrian king a tribute of gold to seal an alliance against the Hurri-Mitannian empire. It is likely that this alliance prompted Saushtatar, the emperor of Mitanni, to invade Assyria, and sack the city of Ashur, after which Assyria became a sometime vassal state, with Ashur-nadin-ahhe I being deposed by Shaustatar and replaced by his own brother Enlil-nasir II (1430–1425 BC) in 1430 BC, who was then made to pay tribute to the Mitanni. Ashur-nirari II (1424–1418 BC) had an uneventful reign, and appears to have also paid tribute to the Mitanni Empire.
The Assyrian monarchy survived, and the Mitannian influence appears to have been short lived.
The Mitanni kingdom was referred to as the Maryannu, Nahrin or Mitanni by the Egyptians, the Hurri by the Hittites, and the Hanigalbat by the Assyrians. The different names seem to have referred to the same kingdom and were used interchangeably, according to Michael C. Astour. Hittite annals mention a people called "Hurri" (""), located in northeastern Syria. A Hittite fragment, probably from the time of Mursili I, mentions a "King of the Hurri". The Assyro-Akkadian version of the text renders "Hurri" as "Hanigalbat". Tushratta, who styles himself "king of Mitanni" in his Akkadian Amarna letters, refers to his kingdom as Hanigalbat.
