Monday marks the 40th anniversary of Iran's Islamic Revolution. In 1979, the pro-US monarchy of Mohammad Reza Shah Pahlavi was overthrown.
Since then, Iran has been under Islamic rule, led by clerical leaders, a social system that strictly interprets Islamic tenets, and an anti-American policy.
On Monday, ceremonies to commemorate the Islamic Revolution will be held, and in the capital Tehran President Hassan Rouhani is scheduled to deliver a speech. Attention is focused on how the president will address current issues.
The country is exploring ways to navigate Islamic rule, and to deal with an economic slump amid increased pressure from the administration of US President Donald Trump.
Iran's economic downturn began after the US unilaterally withdrew from an international accord on Iran's nuclear program in 2018 and reinstated sanctions on Tehran.
Last year, people's frustration over the sluggish economy led to protests across the country. Some of the protestors also criticized the country's strict Islamic rule, highlighting rising tensions, especially among the nation's youth.
About 30 percent of Iran's youth are unemployed.
With nearly 70 percent of the population born after the revolution, people's values are becoming more diverse. The penetration of the Internet is boosting that trend.
