The colonial powers that strove to control Iran because of its geopolitical location were Russia and Britain. Russia controlled the north of the country while the south was under the British. The people tried to constitutionalise their country when the King repeatedly failed to deliver even though he promised to. Twice in the early modern period did Iran try to become a democracy with a constitution and rights for the people.

The continued interest of the Colonisers in the oil of Iran meant that they were not willing to let the people have a fair share of say or profit in the way the national resources of the country were used.
