Water scarcity in Iran is caused by high climatic variability, uneven distribution of water, over exploitation of available water resources,and prioritization of economic development. Water scarcity in Iran is further exacerbated by climate change.

Public protests took place in several cities in Iran beginning on 28 December 2017 and continued into early 2018, sometimes called the Dey protests. The first protest took place in Mashhad, Iran's second-largest city by population, initially focused on the economic policies of the country's government; as protests spread throughout the country, their scope expanded to include political opposition to the theocratic regime of Iran and its longtime Supreme Leader, Ali Khamenei. The Iranian public showcased their fury in the protests with a wide repertoire of chants aimed at the regime and its leadership. According to The Washington Post, protesters' chants and attacks on government buildings upended a system that had little tolerance for dissent, with some demonstrators even shouting "Death to the dictator!"—referring to Supreme Leader Ayatollah Ali Khamenei—and asking security forces to join them.
