Babylonians in the context of "Roman abacus"

Media (Old Persian: 𐎶𐎠𐎭 Māda; Greek: Μηδία Mēdía; Akkadian: Mādāya) was a political entity centered in Ecbatana that existed from the 7th century BCE until the mid-6th century BCE and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference of the Assyrians in the Zagros region led to the process of unifying the Median tribes. By 612 BCE, the Medes became strong enough to overthrow the declining Assyrian empire in alliance with the Babylonians. However, contemporary scholarship tends to be skeptical about the existence of a united Median kingdom or state, at least for most of the 7th century BCE.

According to classical historiography, Media emerged as one major power of the ancient Near East after the collapse of Assyria. Under Cyaxares (r. 625–585 BCE), the kingdom's borders were expanded to the east and west through the subjugation of neighboring peoples, such as the Persians and Armenians. Media's territorial expansion led to the formation of the first Iranian empire, which at its height would have exercised authority over more than two million square kilometers, stretching from the eastern banks of the Halys River in Anatolia to Central Asia. In this period, the Median empire was one of the great powers in the ancient Near East alongside Babylon, Lydia, and Egypt. During his reign, Astyages (r. 585–550 BCE) worked to strengthen and centralize the Median state, going against the will of tribal nobility, which may have contributed to the kingdom's downfall. In 550 BCE, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.

The history of astronomy focuses on the efforts of civilizations to understand the universe beyond earth's atmosphere.Astronomy is one of the oldest natural sciences, achieving a high level of success in the second half of the first millennium. Astronomy has origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory. Early astronomical records date back to the Babylonians around 1000 BC. There is also astronomical evidence of interest from early Chinese, Central American and North European cultures.

Astronomy was used by early cultures for timekeeping, navigation, spiritual and religious practices, and agricultural planning. Ancient astronomers observed and charted the skies in an effort to learn about the workings of the universe. During the Renaissance Period, revolutionary ideas emerged about astronomy. One such idea was contributed in 1543 by Polish astronomer Nicolaus Copernicus, who developed a heliocentric model that depicted the planets orbiting the sun. This was the start of the Copernican Revolution, with the invention of the telescope in 1608 playing a key part. Later developments included the reflecting telescope, astronomical photography, astronomical spectroscopy, radio telescopes, cosmic ray astronomy, infrared telescopes, space telescopes,ultraviolet astronomy, X-ray astronomy, gamma-ray astronomy, space probes, neutrino astronomy, and gravitational-wave astronomy.

The Guti (/ˈɡuːti/), also known by the derived exonyms Gutians or Guteans, were a people of the ancient Near East who both appeared and disappeared during the Bronze Age. Their homeland was known as Gutium (Sumerian: 𒄖𒌅𒌝𒆠, Gutūm or 𒄖𒋾𒌝𒆠, Gutium).Conflict between people from Gutium and the Akkadian Empire has been linked to the collapse of the empire, towards the end of the 3rd millennium BCE. Although economic factors, climate change and internal strife also played a part. The Guti subsequently overran southern Mesopotamia and formed the short-lived Gutian dynasty of Sumer, overseeing a period of economic decline. The Sumerian king list suggests that the Guti ruled over Sumer for several generations following the fall of the Akkadian Empire.

By the mid 2nd millennium BCE, use of the name "Gutium", by the Assyrians and Babylonians of Mesopotamia, was extended to include all foreigners from northwestern Iran, between the Zagros Mountains and the Tigris River. Various tribes and places to the east and northeast, regardless of ethnicity, were often referred to as Gutians or Gutium, and the name no longer referred to one specific people . For example, Assyrian royal annals use the term Gutians in relation to populations known to have been Medes or Mannaeans. As late as the reign of Cyrus the Great of Persia, the famous general Gubaru (Gobryas) was described as the "governor of Gutium".

Nineveh was an ancient Near Eastern city of Upper Mesopotamia, located in the modern-day city of Mosul in northern Iraq. It is located on the eastern bank of the Tigris River and was the capital and largest city of the Neo-Assyrian Empire—and potentially the wealthiest city in the ancient world. Today, it is a common name for the half of Mosul that lies on the eastern bank of the Tigris, and the country's Nineveh Governorate takes its name from it.

It was the largest city in the world for approximately fifty years until the year 612 BC when, after a bitter period of civil war in Assyria, it was sacked by a coalition of its former subject peoples including the Babylonians, Medes, and Scythians. The city was never again a political or administrative centre, but by Late Antiquity it was the seat of an Assyrian Christian bishop of the Assyrian Church of the East. It declined relative to Mosul during the Middle Ages and was mostly abandoned by the 14th century AD after the massacres and dispersal of Assyrian Christians by Timur.

However, contemporary scholarship tends to be skeptical about the existence of a united Median kingdom or state, at least for most of the 7th century BCE.The Median dynasty was, according to the ancient Greek historian Herodotus, a dynasty composed of four kings who ruled for 150 years under the Median Empire. If Herodotus' story is accurate, the Medes were unified by a man named Deioces, the first of the four kings who would rule the Median Empire; a mighty empire that included large parts of Iran and eastern Anatolia.According to classical historiography, Media emerged as one major power of the ancient Near East after the collapse of Assyria. Under Cyaxares (r. 625–585 BC), the kingdom's borders were expanded to the east and west through the subjugation of neighboring peoples, such as the Persians and Armenians. Media's territorial expansion led to the formation of the first Iranian empire, which at its height would have exercised authority over an area of 2.8million square kilometers, stretching from the eastern banks of the Halys River in Anatolia to Central Asia. In this period, the Median empire was one of the great powers in the ancient Near East alongside Babylon, Lydia, and Egypt.

In 550 BC, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.While it is generally accepted that the Medes played a significant role in the ancient Near East after the fall of Assyria, historians debate the existence of a Median empire or even a kingdom. Some scholars accept the existence of a powerful and organized empire that would have influenced the political structures of the later Achaemenid empire. Others argue that the Medes formed a loose confederation of tribes rather than a centralized state.
