Red SeaEdit
The Red Sea is a long, narrow sea that forms a seaward extension of the Indian Ocean, spanning between the northeastern edge of Africa and the southwestern edge of the Arabian Peninsula. It runs roughly 2,300 kilometers in length and reaches up to about 355 kilometers in width, with a maximum depth that varies across its floor. The sea’s northern terminus connects to the Mediterranean Sea through the Suez Canal, a man-made artery opened in the 19th century that dramatically shortened transoceanic routes. At its southern end, the Red Sea narrows through the Bab el Mandeb strait to the Gulf of Aden and thence to the Arabian Sea. The Red Sea is the surface expression of the Red Sea Rift, part of the broader East African Rift system, where the African Plate and the Arabian Plate are moving apart.

Geography
Physical setting and boundaries. The sea lies between the coasts of Egypt, the Sudan and other Arabia states on the African and Asian sides, with prominent waterways including the Gulf of Suez at the northern end and the Gulf of Aqaba to the east. It is linked to the Indian Ocean through the Bab el Mandeb strait and to the Mediterranean Sea through the Suez Canal. The shoreline is a mix of desert coastlines, rocky shores, and burgeoning port cities that reflect a long history of maritime activity. Gulf of Aden Bab el Mandeb Gulf of Aqaba
Hydrography and climate. The Red Sea is relatively warm and saline, a consequence of high evaporation in an arid climate and limited deep-water exchange with the open ocean in places. These conditions support prolific coral reefs and a distinctive marine community, while also conferring a sensitivity to stresses such as rising temperatures and coastal development. The sea’s margins host a range of coastal habitats, from tidal flats to fringing reefs, many of which have become focal points for tourism, conservation, and fisheries. Coral reef Climate change
Biodiversity and ecology. The Red Sea hosts a rich assemblage of tropical and subtropical species, including many reef-building corals, reef fish, and organisms adapted to high salinity and warm temperatures. Its biodiversity has long attracted scientists and divers, and it remains a key area for studies of coral resilience and marine biogeography. Biodiversity Coral reef
Ports and navigation. Along its coasts lie major commercial centers and ports that serve regional economies and global commerce. Notable examples include Port Sudan, Jeddah, and coastal resorts such as Sharm El-Sheikh and Hurghada in the Egyptian and Saudi contexts, as well as inland hubs connected to the canal system and international trade routes.

History
Antiquity and trade. The Red Sea has long been a conduit for exchange between Africa, the Levant, and the hinterlands of the Arabian Peninsula. Ancient trade networks moved precious metals, aromatics, and goods between civilizations that bordered the sea, helping to knit together economies that later formed the foundations of modern states.

Modern transformation: the Suez Canal and imperial era. The opening of the Suez Canal in 1869 marked a turning point in global navigation, turning a long voyage around Africa into a direct, day-length shorter passage between Europe, the Middle East, and Asia. The canal’s expansion in the 2010s further integrated global shipping networks and underscored the strategic importance of the Red Sea corridor. Suez Canal Canal expansion
Contemporary security and governance. In the late 20th and early 21st centuries, the Red Sea corridor became a focal point for maritime security and regional diplomacy as shipping volumes grew and geopolitical rivalries intersected with global energy flows. This has drawn the attention of international navies, regional authorities, and commercial interests alike. Maritime security Regional diplomacy
Economy and shipping
Global trade artery. A substantial share of world trade passes through the Suez Canal and the Red Sea region, linking the Indian Ocean basin with the Mediterranean and Europe. The canal’s passages are a lifeline for energy shipments, manufactured goods, and raw materials, contributing to price stability and supply-chain reliability for economies around the world.

Coastal economies and development. Coastal states bordering the Red Sea rely on ports for fishing, tourism, and industrial activity, as well as on cross-border commerce and infrastructure projects that connect inland economies to global markets. Initiatives to expand port capacity, logistics corridors, and tourism infrastructure reflect a broader strategy of leveraging the sea for growth while attempting to balance environmental protection.

Tourism and recreation. The Red Sea’s shores and islands are famous for diving and marine experiences, with destinations that attract international visitors seeking biodiversity, underwater landscapes, and cultural heritage. This tourism draws investment and supports local communities while raising environmental considerations that require sustainable management. Diving Tourism
Environment and climate
Environmental pressures. Coastal development, overfishing, wastewater management, and climate impacts pose challenges to the Red Sea’s delicate reef ecosystems. Conservation and responsible tourism policies, coupled with science-based management of fisheries and protected areas, are central to preserving the sea’s ecological integrity while sustaining economic activity. Conservation Fisheries management
Resilience and adaptation. The unique combination of high temperatures, salinity, and nutrient dynamics makes the Red Sea reef systems both resilient in some respects and vulnerable in others. Ongoing research and monitoring aim to understand how warming oceans and human pressures affect coral health, with implications for biodiversity and coastal livelihoods.

Geopolitics and security
Strategic chokepoint and diplomacy. The Red Sea and its gateways, especially the Bab el Mandeb strait and the Suez Canal, are among the world’s most strategically important maritime routes. The security of these passages has implications for energy shipments, regional stability, and international commerce, prompting collaboration among regional states and global actors.

Piracy, conflict, and risk management. The proximity of conflict zones and non-state actors has at times raised concerns about piracy and shipping risk in the Gulf of Aden and adjacent waters. International naval patrols, counter-piracy efforts, and risk-management practices by commercial shippers have become common features of Red Sea transit.

Sovereignty, development, and criticism. Projects to expand port capacity, infrastructure, and military presence in the region are often framed as essential for stability and economic progress by some observers, while others criticize external involvement or rapid militarization as potentially compromising sovereignty or local governance. Proponents emphasize sovereignty, rule of law, and open trade as foundations for prosperity. Sovereignty Infrastructure development Rule of law
Controversies and debates from a practical perspective. Debates frequently center on how best to balance security with civil liberties, sovereignty with international cooperation, and rapid economic development with environmental protection. Critics may frame certain security measures as heavy-handed or external-influence-driven, while supporters argue that predictable rules, clear property rights, and robust security are prerequisites for long-run growth and regional peace. In this framing, the aim is to maintain uninterrupted commerce, sea-lane reliability, and local prosperity through stable governance and market-oriented policies.
