Old Assyrian Empire in the context of "Kings of Assyria"

Babylonia (/ˌbæbɪˈloʊniə/; Akkadian: 𒆳𒆍𒀭𒊏𒆠, māt Akkadī) was an ancient Akkadian-speaking state and cultural area based on the city of Babylon in central-southern Mesopotamia (present-day Iraq and parts of Syria). It emerged as an Akkadian-populated but Amorite-ruled state c. 1894 BC. During the reign of Hammurabi and afterwards, Babylonia was retrospectively called "the country of Akkad" (māt Akkadī in Akkadian), a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the linguistically related state of Assyria in Upper Mesopotamia, and with Elam to the east. Babylonia briefly became the major power in the region after Hammurabi (fl. c. 1792–1752 BC middle chronology, or c. 1696–1654 BC, short chronology) created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire. The Babylonian Empire rapidly fell apart after the death of Hammurabi and reverted to a small kingdom centered around the city of Babylon.

Like Assyria, the Babylonian state retained the written Akkadian language for official use, despite its Northwest Semitic-speaking Amorite founders and Kassite successors, who spoke a language isolate. The state retained the Sumerian language in sacred texts for the Babylonian religion, but already by the time Babylon was founded, this was no longer a spoken language, having been replaced by Akkadian. The earlier Akkadian and Sumerian traditions played a major role in the descendant Babylonian culture, and the region would remain an important cultural center, even under its protracted periods of outside rule.

The king of Assyria (Akkadian: Iššiʾak Aššur, later šar māt Aššur) was the ruler of the ancient Mesopotamian kingdom of Assyria, which was founded in the late 21st century BC and fell in the late 7th century BC. For much of its early history, Assyria was little more than a city-state, centered on the city Assur, but from the 14th century BC onwards, Assyria rose under a series of warrior kings to become one of the major political powers of the Ancient Near East, and in its last few centuries it dominated the region as the largest empire the world had seen thus far. Ancient Assyrian history is typically divided into the Old, Middle and Neo-Assyrian periods, all marked by ages of ascendancy and decline.

The ancient Assyrians did not believe that their king was divine himself, but saw their ruler as the vicar of their principal deity, Ashur, and as his chief representative on Earth. In their worldview, Assyria represented a place of order while lands not governed by the Assyrian king (and by extension, the god Ashur) were seen as places of chaos and disorder. As such it was seen as the king's duty to expand the borders of Assyria and bring order and civilization to lands perceived as uncivilized. As Assyria expanded, its rulers gradually adopted grander and more boastful titles. Early kings used Iššiʾak Aššur (representative/viceroy of Ashur), considering the god Ashur to be the true king. From the time of Ashur-uballit I (14th century BC), the rulers instead used king (šar). In time, further titles, such as "king of Sumer and Akkad", "king of the Universe" and "king of the Four Corners of the World", were added, often to assert their control over all of Mesopotamia.

Yamhad (Yamḫad) was an ancient Semitic-speaking kingdom centered on Ḥalab (Aleppo) in Syria. The kingdom emerged at the end of the 19th century BC and was ruled by the Yamhad dynasty, who counted on both military and diplomacy to expand their realm. From the beginning of its establishment, the kingdom withstood the aggressions of its neighbors Mari, Qatna and the Old Assyrian Empire, and was turned into the most powerful Syrian kingdom of its era through the actions of its king Yarim-Lim I. By the middle of the 18th century BC, most of Syria minus the south came under the authority of Yamhad, either as a direct possession or through vassalage, and for nearly a century and a half, Yamhad dominated northern, northwestern and eastern Syria, and had influence over small kingdoms in Mesopotamia at the borders of Elam. The kingdom was eventually destroyed by the Hittites, then annexed by Mitanni in the 16th century BC.

Yamhad's population was predominately Amorite, and had a typical Bronze Age Syrian culture. Yamhad was also inhabited by a substantial Hurrian population that settled in the kingdom, adding the influence of their culture. Yamhad controlled a wide trading network, being a gateway between the eastern Iranian plateau and the Aegean region in the west. Yamhad worshiped the traditional Northwest Semitic deities, and the capital Halab was considered a holy city among the other Syrian cities as a center of worship for Hadad, who was regarded as the main deity of northern Syria.
