Abstract: Qajar dynasty in Iran began with the great evolutions of the world which also influenced developments of Iran. European countries began widespread trade with the countries of the East and pushed them towards a monoculture economy and as a result Iranian farmers cultivated commercial crops. English’s need for the benefits of opium business and high price of cotton as a result of civil wars of America helped the growth of commercial and profitable farming in Iran. This process had no positive outcome for the rural population of Iran and eventually affected Iran’s craft and new industry. It also facilitated migration of a large number of unemployed people of agricultural and industrial sectors out of the country.
