Iran Ranks First Among the World’s Oldest Countries
List of the Oldest Countries in the World
The Oldest Country in the World Based on the Age of Organized Government
According to the latest report published by the reputable platform World Population Review for 2025, Iran has ranked first globally in the classification of the “oldest countries” based on the formation date of an organized government. This ranking, which relies on historical data and credible international sources, identifies Iran as the oldest country under this criterion, with a history dating back to approximately 3200 BCE.
What Are the Criteria of World Population Review?
In its report, World Population Review emphasizes that determining the “oldest country in the world” in absolute terms is not possible, as the concepts of country, borders, and political sovereignty have undergone significant changes throughout history. Therefore, the platform applies several specific criteria for its rankings, the most important of which include:
- The date of the earliest evidence of an organized government
- Continuity of political structures within a given territory
- Recorded historical evidence in reliable sources
Based on the criterion of the earliest known organized government, Iran ranks first, with an approximate date of 3200 BCE. Additionally, in another ranking based on the criterion of the earliest date of self-sovereignty, Iran again holds the top position, although the date cited under this criterion is around 2600 BCE.
Historical Roots of This Ranking
This ranking points to the extremely ancient political structures of the Iranian Plateau, a region that has been home to the formation of civilizations and organized governments for thousands of years. The Elamite civilization in southwestern Iran is considered one of the most significant early examples of organized governance in the ancient world and played a notable role in the region’s political history.
Historians emphasize that throughout thousands of years—despite changes in dynasties and political systems—Iran has consistently been recognized as a major civilizational and political center in West Asia. This historical continuity is one of the main reasons for Iran’s position in this ranking.

The Difference Between “Ancient Civilization” and “Oldest Country”
World Population Review also notes that there is an important distinction between the concepts of an “ancient civilization” and the “oldest country.” Many nations may possess very ancient civilizations, but in terms of the definition of state structures and political sovereignty, they cannot necessarily be directly equated with modern countries. Iran’s ranking in this report is based on a clear and well-documented definition of an organized government.
Perspective of Regional Official Sources
In this context, the official news agency of the United Arab Emirates (WAM) has also referred to Iran in its official reports as one of the world’s oldest and richest human civilizations. Although these reports do not directly form part of the World Population Review ranking, the emphasis by regional official sources on the antiquity of Iranian civilization aligns with international historical assessments.
Summary
- In the World Population Review 2025 report, Iran ranks first globally based on the criterion of the age of organized government.
- This ranking is based on specific historical definitions and should not be interpreted in absolute terms without reference to the stated criteria.
- Iran’s civilizational antiquity, continuity of political structures, and historical role in the formation of governments are among the main factors behind this position.
- References by regional official sources, including the United Arab Emirates, to the ancient nature of Iranian civilization further reinforce the credibility of this historical perspective.
