Question

what were the reasons for emergence of new states in late 18th century

Answer 1

Increased overseas trade is the right answer.  

In the 18th century France, there emerged a new group called the Middle Class. Their main occupation was overseas trade and the production of goods like woolen and silk textiles. The goods manufactured by this class were often bought by a rich section of society. Moreover, some of them were lawyers or administrative officials. This group condemned the idea of privileges by birth and gave more value to the qualities of a person.
