Capital: Tehran

View of Tehran, the capital of Iran

Tehran – Iran’s capital at the southern foot of the Alborz Mountains.

Tehran is the capital and largest city of Iran. Located south of the Alborz Mountains, it became the national capital under Agha Mohammad Khan Qajar in 1786 and later expanded into the country’s main political, administrative, financial, and cultural center. The city contains Qajar-era palaces, major museums, government institutions, universities, commercial districts, and a large metropolitan transport network. Proposals to move the capital toward Iran’s southern coast have been studied, but Tehran remains the current national capital and seat of government.

📜 Timeline of Tehran

12th century: The earliest surviving written references specifically describing the locality of Tehran date from this period, although settlement in the area is older.

1786: Agha Mohammad Khan Qajar chose Tehran as his capital during the rise of the Qajar dynasty.

1906: Tehran became a major center of events surrounding Iran’s Constitutional Revolution and the establishment of a constitutional system.

1971: The monument now known as Azadi Tower opened as Shahyad Tower.

2025–2026: President Masoud Pezeshkian revived proposals to relocate the capital because of Tehran’s water shortages, groundwater depletion, land subsidence, earthquake exposure, congestion, and infrastructure pressures. The southern Makran coast emerged as a possible region for further study, but no legal transfer of the capital occurred.

February 2026: War involving Iran, the United States, and Israel began after strikes on Iran, placing new pressure on national infrastructure, trade, energy flows, and the wider economy.

August 2026: Tehran remained Iran’s capital and seat of government while the conflict continued. War damage, trade disruption, inflation, currency weakness, and pressure on public and industrial infrastructure continued to affect conditions across the country.

Capital Relocation Proposal

Iran has discussed moving its capital away from Tehran because of long-running pressures on the city. President Masoud Pezeshkian has cited water scarcity, groundwater depletion, land subsidence, earthquake risk, population pressure, and infrastructure constraints as reasons to reconsider concentrating so many national functions in Tehran.

The Makran region on Iran’s southern coast, along the Gulf of Oman, has been discussed as a possible location for a future political and administrative center. Government bodies have examined the idea and feasibility work has been undertaken, including geographic and environmental studies. Makran is a broad coastal region rather than a selected new capital city.

No new Iranian capital has been legally established. There is no completed capital transfer, fixed relocation date, or replacement city that should be listed instead of Tehran. Makran remains a proposed and studied option, while Tehran continues to function as Iran’s capital and seat of national government.

2026 Conflict and Recovery Context

The war that began in late February 2026 changed the immediate context in which Tehran functions as the national capital. By August, hostilities and attempts to reach a lasting settlement were still unresolved. Disruption around the Strait of Hormuz also affected shipping, oil flows, imports, and regional trade.

Inside Iran, the conflict added to existing economic pressures. Infrastructure damage, reduced industrial activity, disrupted trade, high inflation, currency depreciation, and weaker government revenues affected the wider economy. These conditions also influence Tehran because it contains central government institutions, major businesses, financial activity, universities, hospitals, and national transport connections.

The situation remains fluid, so wartime economic figures and damage assessments can change as new information becomes available. Tehran continues to serve as Iran’s national capital and seat of government throughout the conflict.

Did you know? Tehran became Iran’s capital in 1786, when Agha Mohammad Khan Qajar selected the city during the establishment of Qajar rule. Proposals to relocate the capital have resurfaced several times, but Tehran remains the capital.

Tehran remains Iran’s seat of national government and its largest urban center. Makran has been proposed and studied as a possible future location for national functions, but no legal capital transfer has taken place.
