What event significantly improved the fortunes of Aden in 1869?

The building of the Suez Canal in 1869 significantly improved the fortunes of Aden due to its strategic location. The canal provided a direct maritime route between Europe and Asia, drastically reducing travel time for ships. Aden, situated at the southern entrance to the Red Sea, became a vital coaling and supply station for vessels traveling through the canal. This influx of maritime traffic increased trade and economic activity in Aden, positioning it as a hub in international shipping routes. The canal enhanced Aden's importance to both commerce and naval operations, influencing the geopolitics of the region and contributing to its development during that period.
