After the 1979 Revolution in Iran, the Revolution Council assumed legislative responsibilities until July 1980 and lowered the voting age in parliamentary elections from 20 to 16 in January 1980. However, in 1981; the voting age was lowered by the 1st parliament to 15. After 18 years, in 1999, the voting age was increased to 16 and one year after it was changed back to 15. The minimum voting age for presidential elections was also decided at 15 by the parliament in 1985. Finally in January 2007, in an unprecedented move, the 7th parliament increased the voting age for both parliamentary and presidential elections to 18, a change that sparked a new round of debates over the issue.*
Expert reports on these changes are available here.
