Imperial cult in the context of "Chinese emperors"

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 Roman imperial cult (Latin: cultus imperatorius) identified emperors and some members of their families with the divinely sanctioned authority (auctoritas) of the Roman State. Its framework was based on Roman and Greek precedents, and was formulated during the early Principate of Augustus. It was rapidly established throughout the Empire and its provinces, with marked local variations in its reception and expression.

Augustus's reforms transformed Rome's Republican system of government to a de facto monarchy, couched in traditional Roman practices and Republican values. The princeps (emperor) was expected to balance the interests of the Roman military, Senate and people, and to maintain peace, security and prosperity throughout an ethnically diverse empire. The official offer of cultus to a living emperor acknowledged his office and rule as divinely approved and constitutional: his Principate should therefore demonstrate pious respect for traditional Republican deities and mores.

Throughout Chinese history, "Emperor" (Chinese: 皇帝; pinyin: Huángdì) was the superlative title held by the monarchs of imperial China's various dynasties. In traditional Chinese political theory, the emperor was the "Son of Heaven", an autocrat with the divine mandate to rule all under Heaven. Emperors were worshiped posthumously under a secular imperial cult. The lineage of emperors descended from a paternal family line constituted a dynasty, and succession in most cases theoretically followed agnatic primogeniture. The emperor of China was an absolute monarch, though in the late Qing reforms plans were made to move the emperor to a constitutional monarch.

During the Han dynasty, Confucianism gained sanction as the official political theory. The absolute authority of the emperor came with a variety of governing duties and moral obligations; failure to uphold these was thought to remove the dynasty's Mandate of Heaven and to justify its overthrow. In practice, emperors sometimes avoided the strict rules of succession and dynasties' purported "failures" were detailed in official histories written by their successful replacements or even later dynasties. The power of the emperor was also limited by the imperial bureaucracy, which was staffed by scholar-officials, and eunuchs during some dynasties. An emperor was also constrained by filial obligations to his ancestors' policies and dynastic traditions, such as those first detailed in the Ming-era Huang-Ming Zuxun (Ancestral Instructions).

The Early Dynastic Period, also known as Archaic Period or the Thinite Period (from Thinis, the hometown of its rulers), is the era of ancient Egypt that immediately follows the unification of Upper and Lower Egypt in c. 3150 BC. It is generally taken to include the First Dynasty and the Second Dynasty, lasting from the end of the archaeological culture of Naqada III until c. 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the Egyptian capital moved from Thinis to Memphis, with the unified land being ruled by an Egyptian god-king. In the south, Abydos remained the major centre of ancient Egyptian religion; the hallmarks of ancient Egyptian civilization, such as Egyptian art, Egyptian architecture, and many aspects of Egyptian religion, took shape during the Early Dynastic Period.

Before the unification of Egypt, the land was settled with autonomous villages. With the early dynasties, and for much of Egypt's history thereafter, the country came to be known as "The Two Lands" (referencing Upper and Lower Egypt). The pharaohs established a national administration and appointed royal governors, and buildings of the central government were typically open-air temples constructed of wood or sandstone. The earliest Egyptian hieroglyphs appear just before this period, though little is known of the spoken language that they represent.

The Ptolemaic cult of Alexander the Great was an imperial cult in ancient Egypt during the Hellenistic period (323–31 BC), promoted by the Ptolemaic dynasty. The core of the cult was the worship of the deified conqueror-king Alexander the Great, which eventually formed the basis for the ruler cult of the Ptolemies themselves. The head priest of the imperial cult was the chief priest in the Ptolemaic Kingdom.
