Why did mesopotamian cities grow and what were they like

Mesopotamia is one of the earliest known civilizations and developed between the Tigris and Euphrates River valleys.

Initially, the groups that settled there were basically nomadic hunter-gatherers and produced instruments made of stone, bone and wood. Gradually, these groups began to grow vegetables and animals. Thanks to this, they began to stay in the places they occupied, forming the first villages.

The first cities of Mesopotamia originated from the villages where the population grew and its inhabitants diversified their crafts. This was the case, for example, of Ur, Uruk, Nippur, Lagash and Eridu, which arose in southern Mesopotamia, Sumer, around 4,000 BC.

In cities, large buildings were erected, such as religious temples, houses, public buildings, streets, bridges and palaces. Around some cities were built walls and watchtowers. The temples of power in the cities were the temples and the royal palace.

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place.
