Battle of Wādī Lakkah (Guadalete)

Months after crossing the strait and burning his boats — so the famous story goes — Ṭāriq ibn Ziyād met the Visigothic king Roderic at the river the Arabic sources call Wādī Lakkah. Through several days of fighting in Ramaḍān 92 the Gothic host disintegrated, betrayed on its wings by rivals of the king, and Roderic vanished into the river's legend.

The kingdom's spine broke with its army: within five years the peninsula, bar the northern mountains, had become al-Andalus — the entry point of the civilisation whose last chapter this database records at Granada, 897.

The month is secure; the 28 Ramaḍān tradition for the decisive day is common but not unanimous, so month precision it is.
