Which socioeconomic system was gradually replaced by the growth of towns and cities during the Romanesque period?

The correct answer to the following question will be "Monasticism".

Explanation:

The great raid of monasticism throughout the 10th and 11th centuries, when Europe first recovered a form of economic stability after the fall of Rome, led to Romanesque art. After almost 600 years of dormancy, the art of monumental architecture was resurrected in western Europe throughout the Romanesque era. Monasticism is a traditional way of life where worldly desires are renounced instead. It is estimated that Bon has a rich ascetic history. So, Monasticism was the socioeconomic system that was eventually replaced during the Romanesque period by the growth of both the towns and cities.

Therefore, it is the right answer.
