Abraha

Abraha was the Aksumite commander who seized the rule of Yemen, built a cathedral to outshine the Kaaba — and marched on Mecca with an elephant, the invasion remembered as the Year of the Elephant.

Originally a commander in the Aksumite expedition that ended Jewish rule in Himyar, Abraha made himself the effective ruler of Yemen under the Negus's nominal suzerainty ¹. He built the cathedral of al-Qullays at San'a — a church meant, the sources say, to draw the Arabs' pilgrimage away from Mecca.

The campaign on Mecca followed, with an elephant at its head. Tradition dates it to the year of the Prophet's birth (~570 CE); the inscriptional evidence scholars prefer points earlier, about 552 CE — the museum records both {cite:tabari-bosworth-1999, watt-1953-mecca}. In the Qur'an's telling (sura 105), the army is destroyed by birds hurling stones; the sira adds the elephant kneeling and refusing to advance ².

However the campaign is reconstructed, "the Year of the Elephant" became the calendar peg of Meccan memory — the year from which everything else in the city was dated, including the Prophet's birth.
