A civilization developed between the Tigris River and the Euphrates River. This civilization is of great significance in human history because it laid the foundation for many subsequent civilizations, including ancient Egypt, ancient Greece and ancient Rome. The civilization of the two river basins began in 5000 BC.

At this time, human beings began to settle in these two basins and established many cities. The earliest city is Sumer, where there are many important cities, such as uruk, Ur and Gudia. These cities have established powerful political, economic and cultural systems and created unique religions, languages and literature.

The civilization of the two river basins ended in 2000 BC, which is called the "New Assyrian Period". During this period, Assyrians began to rule this area and brought new political, military and cultural elements. Assyrian religious belief, art and architectural style have influenced the whole Middle East. Finally, in the 6th century BC, the conquest of the Persian Empire ended this civilization.

Characteristics of the two river basins:

1. The natural environment of the two rivers basin is quite special.

The two river basins are in arid environment, but there are many fertile alluvial plains because most of the low flood plains in the two river basins are in alluvial land with sufficient water in arid environment. The floodplain has fertile soil, which is suitable for planting wheat, barley and other crops, and also promotes the development of agriculture.

2. The religions and cultures of the two river basins are very unique.

In ancient times, there were many religions and cultures here, such as the early Sumerian religion, the rule of Akkadian dynasty, and code of hammurabi in the Babylonian kingdom of Cuba. These religions and cultures have exerted a profound influence on world culture, especially code of hammurabi, which is one of the earliest codes in the world and has influenced many subsequent legal systems.

3. The civilized development of the two river basins is of great significance.

This is one of the important cradles of human civilization, which has nurtured the earliest urban civilization and legal system in the world. There are many important cities here, such as uruk, Ur and Goudier. These cities have established a strong political, economic and cultural system, language and literature. The development of civilization in the two river basins has had a great impact on the progress and development of human society.
