Aksum rose as a major power of the late-antique world, commanding Red Sea trade between the Roman Mediterranean, Arabia and India and minting its own gold, silver and bronze coinage. Its rulers raised giant carved granite stelae, the tallest standing over thirty metres, the largest single pieces of stone ever quarried and erected as monoliths, marking elite tombs. The capital combined royal palaces, terraced platforms and an early adoption of Christianity in the fourth century. Aksum was one of the great cities of its age, ranked by contemporaries among the leading kingdoms.
Aksum demonstrates a powerful indigenous African urban state integrated into Indian Ocean and Mediterranean trade, with monumental engineering and coinage rivalling its contemporaries.
