Which traditional industries supported communities around the Persian Gulf before oil was discovered?

Before the discovery of oil, the economy of the Persian Gulf region was primarily supported by a variety of traditional industries that relied on the sea and the surrounding arid landscape.

The most lucrative and significant occupation was pearl diving, which utilized the region's rich oyster beds to produce some of the world's finest pearls. This industry was a central component of life in the region until the 1930s, when it began to decline due to the introduction of Japanese cultured pearls and shifting labor markets.123

Other essential traditional industries included:

• Fishing: A vital source of subsistence and commerce for coastal communities.32
• Maritime Trade and Shipbuilding: The construction of dhows—traditional lateen-rigged sailing vessels—facilitated regional trade and deep-sea voyaging across the Indian Ocean.324
• Agriculture and Craft: Date growing was widespread, and communities engaged in nomadic herding, camel breeding, sailcloth making, and the production of reed mats.3
• Minor Resource Extraction: The production of goods such as red ochre from islands in the south also contributed to the local economy.3
