Early Bronze Age in the context of "Smelting"

Ancient Egypt was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150 BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of the Early Bronze Age; the Middle Kingdom of the Middle Bronze Age; or the New Kingdom of the Late Bronze Age.

The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt entered an era of slow decline. Over the course of its history, it was invaded or conquered by a number of foreign civilizations, including the Hyksos, the Kushites, the Assyrians, the Persians, and the Greeks and then the Romans. The end of ancient Egypt is variously defined as occurring with the end of the Late Period during the Wars of Alexander the Great in 332 BC or with the end of the Greek-ruled Ptolemaic Kingdom during the Roman conquest of Egypt in 30 BC. In AD 642, the Arab conquest of Egypt brought an end to the region's millennium-long Greco-Roman period.

Shkodër (/ˈʃkoʊdər/ SHKOH-dər, Albanian: [ˈʃkɔdəɾ]; Albanian definite form: Shkodra; historically known as Scodra or Scutari) is the fifth-most-populous city of Albania and the seat of Shkodër County and Shkodër Municipality. Shkodër has been continuously inhabited since the Early Bronze Age (c. 2250–2000 BC), and has roughly 2,200 years of recorded history. The city sprawls across the Plain of Mbishkodra between the southern part of Lake Shkodër and the foothills of the Albanian Alps on the banks of the Buna, Drin and Kir rivers. Due to its proximity to the Adriatic Sea, Shkodër is affected by a seasonal Mediterranean climate with continental influences.

An urban settlement called Skodra was founded by the Illyrian tribe of Labeatae in the 4th century BCE. It became the capital of the Illyrian kingdom under the Ardiaei and Labeatae and was one of the most important cities of the Balkans in ancient times. It has historically developed on a 130 m (430 ft) hill strategically located in the outflow of Lake Shkodër into the Buna. The Romans annexed the city after the third Illyrian War in 168 BC, when the Illyrian king Gentius was defeated by the Roman force of Anicius Gallus. In the 3rd century AD, Shkodër became the capital of Praevalitana, due to the administrative reform of the Roman Emperor Diocletian. With the spread of Christianity in the 4th century AD, the Archdiocese of Scodra was founded and was assumed in 535 by Byzantine Emperor Justinian I.

The Hattians (/ˈhætiənz/) were an ancient Bronze Age people that inhabited the land of Hatti, in central Anatolia (modern Turkey). They spoke a distinctive Hattian language, which was neither Semitic nor Indo-European. Hattians are attested by archeological records from the Early Bronze Age and by historical references in later Hittite and other sources. Their main centre was the city of Hattush. Faced with Hittite expansion (since c. 2000 BC), Hattians were gradually absorbed (by c. 1700 BC) into the new political and social order, imposed by the Hittites, who were one of the Indo-European-speaking Anatolian peoples. The Hittites kept the country name ("land of Hatti") unchanged, which also became the main designation for the Hittite state.

Ancient Egyptian hieroglyphs (/ˈhaɪroʊˌɡlɪfs/ HY-roh-glifs) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic, and alphabetic elements, with more than 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic. Hieroglyphs are thought to be one of four writing systems developed without outside influence, the others being Cuneiforms, Chinese characters, and Mayan script.

The use of hieroglyphic writing arose from proto-literate symbol systems in the Early Bronze Age c. the 33rd century BC (Naqada III), with the first decipherable sentence written in the Egyptian language dating to the 28th century BC (Second Dynasty). Ancient Egyptian hieroglyphs developed into a mature writing system used for monumental inscription in the classical language of the Middle Kingdom period; during this period, the system used about 900 distinct signs. The use of this writing system continued through the New Kingdom and Late Period, and on into the Persian and Ptolemaic periods. Late survivals of hieroglyphic use are found well into the Roman period, extending into the 4th century AD.

Sumer (/ˈsuːmər/) is the earliest known civilization, located in the historical region of southern Mesopotamia (now south-central Iraq), emerging during the Chalcolithic and early Bronze Ages between the sixth and fifth millennium BC. Like nearby Elam, it is one of the cradles of civilization, along with Egypt, the Indus Valley, the Erligang culture of the Yellow River valley, Caral-Supe, and Mesoamerica. Living along the valleys of the Tigris and Euphrates rivers, Sumerian farmers grew an abundance of grain and other crops, a surplus of which enabled them to form urban settlements. The world's earliest known texts come from the Sumerian cities of Uruk and Jemdet Nasr, and date to between c. 3350 – c. 2500 BC, following a period of proto-writing c. 4000 – c. 2500 BC.

Ancient Semitic-speaking peoples or Proto-Semitic people were speakers of Semitic languages who lived throughout the ancient Near East and North Africa, including the Levant, Mesopotamia, Anatolia, the Arabian Peninsula and Carthage from the 3rd millennium BC until the end of antiquity, with some, such as Arabs, Arameans, Assyrians, Jews, Mandaeans, and Samaritans having a historical continuum into the present day.

Their languages are usually divided into three branches: East, Central and South Semitic languages.the oldest attested forms of Semitic date to the early to mid-3rd millennium BC (the Early Bronze Age) in Mesopotamia, the northwest Levant and southeast Anatolia.

The Chalcolithic (/ˈkælkəˌlɪθɪk/ KAL-kə-LI-thik) (also called the Copper Age and Eneolithic) was an archaeological period characterized by the increasing use of smelted copper. It followed the Neolithic and preceded the Bronze Age. It occurred at different periods in different areas, but was absent in some parts of the world, such as Russia, where there was no well-defined Copper Age between the Stone and Bronze Ages. Stone tools were still predominantly used during this period.

The Chalcolithic covers both the early cold working (hammering) of near pure copper ores, as exhibited by the likes of North American Great Lakes Old Copper complex, from around 6,500 BC, through the later copper smelting cultures. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from c. 5,000 BC. The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late 3rd millennium BC. In the Ancient Near East the Copper Age covered about the same period, beginning in the late 5th millennium BC and lasting for about a millennium before it gave rise to the Early Bronze Age.

The north and south celestial poles are the two points in the sky where Earth's axis of rotation, indefinitely extended, intersects the celestial sphere. The north and south celestial poles appear permanently directly overhead to observers at Earth's North Pole and South Pole, respectively. As Earth spins on its axis, the two celestial poles remain fixed in the sky, and all other celestial points appear to rotate around them, completing one circuit per day (strictly, per sidereal day).

The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of +90 degrees and −90 degrees (for the north and south celestial poles, respectively). Despite their apparently fixed positions, the celestial poles in the long term do not actually remain permanently fixed against the background of the stars. Because of a phenomenon known as the precession of the equinoxes, the poles trace out circles on the celestial sphere, with a period of about 25,700 years. The Earth's axis is also subject to other complex motions which cause the celestial poles to shift slightly over cycles of varying lengths (see nutation, polar motion and axial tilt). Finally, over very long periods the positions of the stars themselves change, because of the stars' proper motions. To take into account such movement, celestial pole definitions come with an epoch to specify the date of the rotation axis; J2000.0 is the current standard.
