The Visigoths, led by king Alaric I, cross the Alps and invade northern Italy.
In 401, King Alaric I led the Visigoths across the Alps into northern Italy, signaling a major movement of tribes during the decline of the Western Roman Empire.
King Alaric I and his Visigothic followers traversed the formidable Alpine passes in late 401, emerging into northern Italy. This bold incursion represented one of the first large-scale breaches of the Roman heartland by a barbarian force. Roman defenses, strained by internal strife and depleted legions, proved unable to halt the advance. The invasion disrupted trade routes and settlements, sowing fear among the Roman populace. Alaric’s campaign foreshadowed later sackings of Rome and underscored the empire’s vulnerability. It also marked a key moment in the migration period that reshaped Europe’s political landscape. Historians view this crossing as a turning point in the collapse of centralized Roman authority.

The Council of Clermont begins: called by Pope Urban II, it led to the First Crusade to the Holy Land.
Pope Urban II convened the Council of Clermont, where he called Western knights to liberate the Holy Land, sparking the First Crusade.
On November 18, 1095, Pope Urban II opened the Council of Clermont in France, gathering clergy and nobility to address the advance of Islamic powers. In a fervent speech, he urged Christian knights to take up arms to reclaim Jerusalem and support the Byzantine Empire. His call resonated across Europe, blending religious zeal with promises of forgiveness and land. The council’s decision set into motion the First Crusade, a decades-long military expedition. Thousands of knights, adventurers, and pilgrims responded, reshaping East-West relations. The crusade established crusader states and changed medieval warfare and diplomacy. It also deepened cultural exchanges—and conflicts—between Islam and Christianity. The Council of Clermont thus stands as a landmark in the history of religiously motivated warfare.
