Answer:
Both countries were able to modernize albeit at different times in history, with the changes being led by the indigenous elite and not by external western forces.
Step-by-step explanation:
Both Turkey and Iran have common factors. They were both Muslims countries and both the countries were the few who remained Independent and were not colonized by the West.
Hence, all modernization was led by factions within the society.
However, things turned out to be slightly different. Turkey's founder Kemal Ataturk was an autocratic but believed that he was paving the way for democracy.
On the other hand, Iran's leader Reza Shah Pahvali become an increasingly automatic leader who did not believe in democracy.
Turkey gradually became a 'Military democracy' where elections were held, but the Army held a lot of power to influence internal and external politics.
Iran became a theocracy which also has a powerful army.
What is common now in both countries is how the kemalist and and Islamic policies are increasingly under attack by a new wave of young people.
