Democracy, in the sense of free elections in a free enviroment, has never been tried in Iran since the Constitutional Revolution 1906... and back then pro-constitution, pro-limited power, pro-modernisation forces won. From 1921-79 Iran was a pro-western, secular autocratic monarchy with a virtually powerless parliament. The only exception being the time from 1941-53... and back then the strongest forces were secular nationalists, monarchists, liberals, communists and representatives of certain professions (toilers, merchants etc.). Islamic "conservative" voices weren't dominating and far from unified.
Since 1979 Iran has not seen free and fair elections. They are sham elections, starting with the ridiculous faux "referendum" 1980 in which supposedly over 90% of Iran voted for the islamic republic.
call me a “whatever” but largely, democracy seems to work best in ex English colonys, except Africa, the Middle East, and Asia. Other than that, some wise men saw through the devine Right of Kings, directly to the Devive Right of the Individual. Magna Carta to our Constitution. Evolution of Anglo-Saxon thought /government, throw in Adam Smith and it’s a 1000 to nothing football game (no competition, and they fumble a lot and arm tackle)
