Long ago, people lived in a place called Mesopotamia. 



Ancient Mesopotamian religion was a way of life for many people. It lasted from about 6000 BC until 500 AD. 

Religious life worked through the worship of many different beings. This is called polytheism. 
This way of believing started a long time ago. The earliest ideas began in the 6th millennium BC. 
Many specific names and places appear in these old records. Scholars have found about 2,400 different gods. 
These stories help explain how the world works. One famous story is the Enuma Elish. 
Ancient Mesopotamian religion was a complex system of beliefs and practices. It spanned many centuries, from roughly 6000 BC to 500 AD. 
The development of these beliefs followed several distinct stages. In the 6th millennium BC, early religious thoughts emerged as people settled in permanent urban centers. The mid-4th millennium BC provides the first real evidence of these religions. This period coincided with the invention of writing. At this time, people worshipped the forces of nature. They viewed these forces as providers of sustenance. During the Ubaid Period, between 5500 and 3700 BCE, people worshipped a mother goddess named Ninhursag. By the 3rd millennium BC, worship changed significantly. Objects of worship became personified as a vast cast of divinities with specific functions. 
Mesopotamian religion was primarily polytheistic. This means people believed in many different gods and goddesses. They also practiced henotheism. This is when devotees focus on one specific god as superior. Each city-state often had its own patron or tutelary deity. For example, Enki was linked to the city of Eridu. Marduk was the patron of Babylon. Ashur was the patron of the city of Assur. 
The gods themselves were anthropomorphic. This term means they had human forms and human-like qualities. They could eat and drink, and even suffer from drunkenness. However, they were much more perfect than humans. They were all-knowing, all-seeing, and immortal. They also possessed a terrifying brightness called melammu. This light produced an immediate sense of awe in people. 
Cosmology, or the study of the universe, was central to their worldview. While many records are lost, the Enuma Elish provides key details. 
Political structures were deeply tied to these religious ideas. In early Assyria, authority was an oligarchy rather than a monarchy. Power was shared between an assembly of elders, a hereditary ruler, and an eponym. The eponym, or limmum, was elected annually by lot. This person managed the economic administration of the city. 
History shows that these religious systems eventually changed. The Achaemenid Empire conquered Mesopotamia in 539 BC. The Persians did not interfere with native religions. However, the region saw many shifts in influence. Alexander the Great took control in 330 BC. This brought Hellenistic influence to the area. Later, the region became part of the Roman and Sasanian Empires. Christianity was introduced starting in the 2nd century AD. This led to the decline of traditional Mesopotamian polytheism. By the 5th century AD, the old religious systems had largely faded due to Christianization.
