How did the relations of the Greek colonists with the local population develop?

The relationship was formed on the basis of mutually beneficial cooperation, which contributed to the development of crafts and the economy as a whole. The Greek colonists actively traded with the local population. The items of trade were:
1. Handicraft goods
2. Olive oil
3. Wine
4. Cereals (bread)
5. Slaves.
At the same time, the religion and culture of the local population was not touched by the Greeks and remained unchanged, which was the reason for a rather calm attitude towards the Greeks on the part of local residents.
