The Aksumite Kingdom, emerging in the 1st century CE in the northern highlands of Ethiopia and Eritrea, became a powerful Christian state and trade hub. Controlling Red Sea routes, Aksum thrived through the 4th and 5th centuries, exporting luxury goods and minting its own currency. Aksum's legacy includes distinctive architecture, like monumental stelae, and the development of the Ge'ez script. However, the kingdom declined in the 7th century due to shifting trade patterns and environmental challenges, transforming the region's political landscape.
