Iran's turbulent century fuels its current standoffs

Global Watch | 2026-07-11

Iran’s modern political tensions stem from 20th-century struggles between rapid modernization and traditional authority. The Pahlavi dynasty's centralizing project in the 1920s delivered infrastructure and social change but also concentrated power and provoked backlash.

That tension helped produce the 1979 Islamic Revolution and the theocratic system that still governs Iran today.

Under the Pahlavi shahs, Iran pursued top-down modernization. Reza Shah centralized authority, built infrastructure and advanced secular reforms that expanded opportunities for women.

His son accelerated these efforts after 1941, especially through the 1963 White Revolution. Literacy rose sharply and cities gained major infrastructure.

Yet rapid change displaced rural populations and concentrated wealth among connected elites. The 1953 overthrow of Prime Minister Mohammad Mossadegh left a lasting legacy of suspicion toward foreign involvement.

Revolution and theocratic rule

These pressures helped mobilize a broad coalition against the monarchy by the late 1970s. Ayatollah Ruhollah Khomeini offered a vision of clerical oversight that appealed to religious traditionalists, leftists and liberals.

Mass protests paralyzed the country. The shah departed in January 1979. Khomeini returned weeks later.

A referendum created the Islamic Republic, with ultimate authority vested in a supreme leader. Early coalitions fractured as hardliners consolidated power.

The 1979-1981 US embassy hostage crisis deepened Western isolation. Iraq's 1980 invasion triggered an eight-year war that killed or wounded hundreds of thousands and strengthened the Islamic Revolutionary Guard Corps.

Since the war, authority has remained concentrated in the supreme leader. Elected institutions operate within limits set by unelected bodies, including the Guardian Council and the Revolutionary Guard.

Iran presents its nuclear program as a peaceful effort to develop nuclear energy. In practice, it has pursued high levels of uranium enrichment far beyond civilian needs and consistent with nuclear weapons ambitions that serve coercion, blackmail and regional destabilization.

The program has relied on Russian technical assistance and infrastructure support. Russia completed and fueled the Bushehr nuclear power plant and has provided critical components and diplomatic backing.

This assistance has helped Tehran sustain and advance its nuclear activities under international pressure. Iran's dependence on Moscow has grown as it seeks partners to circumvent Western sanctions.

Iran also built networks of allied militant groups across Lebanon, Syria, Iraq, Yemen and Palestinian territories. These activities prompted the United States and European governments to maintain sanctions tied to nuclear issues and support for designated organizations.

The same institutional design that limits domestic flexibility drives external behavior that raises regional risks. Iran has developed ballistic missiles, drones and proxy forces that enable threats to shipping lanes and strikes on neighbors.

These capabilities, paired with high levels of uranium enrichment, create proliferation dangers and raise the potential for rapid escalation. Western and regional governments have responded with sanctions and defensive cooperation because these activities directly target their security interests.

Strategic and domestic costs

Inside Iran, the focus on regime survival has produced persistent hardship and repression that reinforces the regime's external adventurism. Inflation has often exceeded 30 percent in recent years.

The currency has depreciated sharply and youth unemployment remains elevated. Shortages of medicines and goods add daily strain. Millions of educated citizens have emigrated.

Public discontent has surfaced in repeated large demonstrations. Security forces killed an estimated 1,500 people during November 2019 protests over fuel prices and economic conditions.

Later waves linked to living costs and social restrictions followed similar patterns of arrests and force.

Iranian decision-making consistently places regime preservation and external influence above domestic welfare. This combination of internal control and external projection sustains a cycle in which the regime's priorities endanger both its own citizens and regional stability.

This evolution has positioned Iran as a state whose geopolitical weight rests more on its capacity to raise costs for adversaries through asymmetric tools than on broad economic integration.

The resulting standoff with the United States and its partners shows little sign of easing. Inside Iran, the same patterns sustain cycles of protest and repression that reflect unresolved gaps between state priorities and public expectations.
