Overview

Sharjah Mosque, built in the 1980s in traditional style Figure 2. Persian Gulf States: Topography THE FIVE COUNTRIES covered in this volume--Kuwait, Bahrain, Qatar, the United Arab Emirates, and Oman--are all Arab states on the Persian Gulf that share certain characteristics. But they are not the only countries that border the gulf. Iran, Iraq, and Saudi Arabia share the coastline as well, and they too shared in the historical development of the area. Of the five states covered in this volume, Oman has a particular culture and history that distinguish it from its neighbors. It also is the state with the shortest coastline along the Persian Gulf. Most of Oman lies along the Gulf of Oman and the Arabian Sea (see bahrain/bh00_05a.pdf"> fig. 1). The main element that unites these countries is the nature of their involvement with people and nations beyond the region. The gulf has been an important waterway since ancient times, bringing the people who live on its shores into early contact with other civilizations. In the ancient world, the gulf peoples established trade connections with India; in the Middle Ages, they went as far as China; and in the modern era, they became involved with the European powers that sailed into the Indian Ocean and around Southeast Asia. In the twentieth century, the discovery of massive oil deposits in the gulf made the area once again a crossroads for the modern world. Other factors also bring these countries together. The people are mostly Arabs and, with the exception of Oman and Bahrain, are mostly bahrain/bh_glos.asp#Sunni">Sunni (see Glossary) Muslims. Because they live in basically tribal societies, family and clan connections underlie most political and economic activity. The discovery of oil and the increasing contact with the West has led to tremendous material and social changes. Important distinctions exist, however, among the five countries. Bahrain is an island with historical connections to the Persian Empire. Kuwait is separated from the others by Saudi Arabia. In Oman high mountain ranges effectively cut off the country’s hinterland from the rest of the region (see unavail.asp"> fig. 2). Moreover, various tribal loyalties throughout the region are frequently divisive and are exacerbated by religious differences that involve the major sects of Islam-- bahrain/bh_glos.asp#Sunni">Sunni and bahrain/bh_glos.asp#Shia">Shia (see Glossary)--and the smaller Kharijite sect as well as Muslim legal procedures.

Historical Eras

The major periods of {country}’s history at a glance.

  1. Ancient Dilmun

    3000 BCE – 300

    Bahrain formed the heart of the ancient Dilmun civilization, one of the oldest trading cultures in the Persian Gulf, mentioned in Sumerian texts as a sacred land and commercial hub linking Mesopotamia with the Indus Valley. The archipelago's freshwater springs and strategic location made it a prosperous entrepôt. Dilmun later came under Kassite, Assyrian, and eventually Greek influence following Alexander the Great's campaigns.

  2. Persian & Islamic Eras

    300 – 1521

    Bahrain passed through Sasanian Persian control before the rapid spread of Islam incorporated the islands into the Arab-Muslim world in the 7th century CE. The region became a center of the Qarmatian movement, a radical Ismaili sect that established a powerful state in the 9th–10th centuries and briefly disrupted hajj routes. Subsequently, Arab tribal confederacies and Persian governors contested control, while pearl diving and Gulf trade sustained the local economy.

  3. Portuguese Rule

    1521 – 1602

    Portuguese forces seized Bahrain in 1521, incorporating it into their Indian Ocean commercial empire and constructing the fortified Qal'at al-Bahrain as a garrison. Their rule was marked by heavy taxation of the lucrative pearl trade and periodic local resistance. In 1602, Safavid Persian forces under Shah Abbas I expelled the Portuguese and reasserted Persian sovereignty over the archipelago.

  4. Safavid & Al Khalifa Rise

    1602 – 1820

    Bahrain remained under Safavid and later Omani and competing tribal control for much of the 17th and early 18th centuries. In 1783, the Bani Utbah confederation led by the Al Khalifa family decisively expelled the Persian-backed rulers and established the dynasty that governs Bahrain to the present day. The early Al Khalifa period was defined by inter-Gulf rivalries, pearling wealth, and shifting alliances among the major powers of the region.

  5. British Protectorate

    1820 – 1971

    A series of treaties beginning in 1820 and culminating in an 1880 exclusive agreement drew Bahrain firmly into the British sphere of influence, effectively making it a protectorate. Britain managed Bahrain's foreign affairs and defense while the Al Khalifa ruled internally; oil was discovered in 1932, transforming the economy. The 1913 treaty formally recognized Bahrain's distinct status, and Iran renounced its long-standing sovereignty claim in 1970, clearing the path for full independence.

  6. Independent Kingdom

    1971 – present

    Bahrain declared full independence on August 15, 1971, signing a friendship treaty with Britain and joining the Arab League and United Nations. The country navigated regional turbulence — including participation in the 1991 Gulf War coalition and Shia-Sunni sectarian tensions — while diversifying its economy into banking and petroleum refining as oil reserves declined. In 2002, Amir Hamad bin Isa Al Khalifa proclaimed Bahrain a constitutional monarchy, introduced parliamentary elections, and extended voting rights to women.
