What was Gaul like before the Roman invasion?

In the 6th century BC, the main inhabitants of Gaul were Celts, and the Romans called them Gauls. Iberians live in the southwest of Gaul and Ligurians live in the southeast. In BC 1 century, Gaul society was still in the disintegration stage of primitive commune. The clan nobles of the tribe own a large area of land and many livestock, and the bankrupt civilians are attached to the clan nobles. In the 2nd century BC, the Romans invaded Gaul, conquered the south of Gaul, and established Nanxi Province in Nalbot. What was Gaul like before the Roman invasion? From the 7th century BC, before it appeared in modern France, after centuries of integration and communication with the original local residents, the Celtics were divided into three branches in Gaul, namely, Gaul in the middle, Pyrenees in the north and aquitaine in the southwest. Gauls are relatively pure Celts in constitution, living in a vast area from the north of the Garonne River to the Seine River. Bill and Germany are a mixture of Celts and Germans. They migrated from the east bank of the Rhine in the 3rd century BC and settled in the area between the Seine and the Rhine. Ethnically, aquitaine people have the characteristics of mixing Celtic and local Iberians, and they are distributed between the Pyrenees and the Garonne River. These three Celts have the same language, cultural and religious characteristics and similar customs, but they speak different dialects and have different body shapes. They are divided into about 60 states. In organizational form, this state is the tribal alliance of primitive society. Their population is quite different from the amount of land they occupy, and the population can reach several hundred thousand. For example, in the northern states of Bilai and Belovac, according to Caesar's records, the total population is about 400,000. There are only tens of thousands of people in the States of the Pyrenees. There are several tribal areas under each state. Clans and tribes in each state have certain territories and boundaries. The larger and stronger states are Sen nunes, Eduy, Segundo, Lingoni, Afni, Bi Dullis, Sandoni, Removix, Picadon and so on. Gaul's vast land and rich products have long been valued by the ancient Romans. In the 2nd century BC, after three Punic wars, Rome defeated Carthage in North Africa. At the same time, it conquered the Balkans and part of Spain one after another, and got its hands on the areas where the Celts lived. Shortly after the end of the Second Punic War, Rome conquered Gaul in the mountains. After decades of intermittent wars, it occupied the Mediterranean coast of France in 1 18 BC, established the province of Nabang Gaul, established part of Rome's rule over Gaul outside the mountains, and controlled the main roads connecting Celtic residential areas with the Mediterranean region. After Rome conquered Shannan Gaul and Nabang Gaul, it learned more about the Celtic language, habits and culture, and absorbed Celtic soldiers into the army, thus gaining a base for supplementary troops and attacks.
