Iran’s Islamic Republic and 47-Year Tensions

Under the leadership of Ayatollah Ruhollah Khomeini, the 1979 Islamic Revolution ended the pro-Western Pahlavi monarchy in Iran. Following this upheaval, the country was officially renamed the Islamic Republic of Iran, marking the start of a conservative, revolutionary government that continues to rule 47 years later.

Since its establishment, the Islamic Republic has navigated domestic unrest, prolonged wars, and international pressures, particularly from the United States and Israel. The nation has faced economic crises due to repeated sanctions, while simultaneously managing regional conflicts and maintaining influence across the Middle East.

The following table summarises key events in Iran’s modern history:

Over nearly five decades, Iran’s political trajectory has been defined by a mixture of revolutionary zeal, regional assertiveness, and resistance to Western influence. The nation has faced multiple wars, domestic protests, and natural disasters, while its foreign policy has consistently focused on expanding Shia influence in Lebanon, Syria, and Iraq.

Recent escalations, including the 2026 Operation Epic Fury, have resulted in widespread destruction across Iranian cities, targeting military and political centres. In response, Iran launched missile and drone attacks against Israeli and US positions, further destabilising the Middle East.

This historical continuum illustrates the delicate balance Iran maintains between domestic governance, regional power projection, and international diplomacy, highlighting the enduring volatility of its relationship with the United States and its allies.
