Alahis, an Arian duke of Trent and Brescia, emerged as a significant figure in the Lombard kingdom during the late seventh century. His political journey began with a failed rebellion against King Perctarit in the year six hundred eighty, which led to his capture. However, the king chose to pardon him, allowing Alahis to regroup and plan his next move.
In six hundred eighty-eight, Alahis seized the opportunity to rebel once more, this time against Perctarit's successor, Cunipert. His efforts were initially successful, as he managed to force Cunipert into a stronghold on an island in Lake Como. Despite this early triumph, Alahis's reign was marked by tyranny, which ultimately alienated the very people he sought to rule.
The discontent among the populace grew, and in six hundred eighty-nine, Cunipert rallied the men of Piedmont to confront Alahis. The decisive clash occurred at the Battle of Coronate, near Lodi, where Alahis faced a formidable challenge. The battle concluded with Alahis's defeat and death, marking the end of his brief and tumultuous rule over the Lombards.
