Final answer:
The Iran-Iraq War deeply impacted the daily life in Tehran, causing austerity, heightened political friction, and personal freedoms being curtailed, which led to widespread dissatisfaction among the city's younger population.
Step-by-step explanation:
The Iran-Iraq War, which lasted from 1980 to 1988, had a significant effect on daily life in Tehran and influenced the behavior and actions of its residents, including Marjane's parents, a reference likely from the graphic novel 'Persepolis' by Marjane Satrapi. The war led to austerity and social restrictions, fueled in part by the need to support the war effort and the country's conservative Islamic fundamentalist government.
During this time, the government was controlled by conservative Muslim clerics, while a significant portion of the younger population, longing for personal freedoms and exposure to Western culture, found themselves at odds with the state. It was a period marked by scarceness of goods, frequent air raids, and a constant sense of danger which significantly affected the populace's lifestyle, restricting their movements and social interactions. Moreover, the war intensified internal political friction and contributed to the dissatisfaction of young people with the government's policies.
