Andronikos I Komnenos vs Pelagius of Asturias

Andronikos I Komnenos led a revolt against the regency of Empress Maria of Antioch, entering Constantinople with popular support. He had the empress imprisoned and later executed, and then had the young emperor Alexios II strangled, making himself sole ruler.

Andronikos I instigated a massacre of Latin (Western European) residents in Constantinople, targeting merchants and their families. The violence killed thousands and severely damaged Byzantine relations with the West, contributing to the later Fourth Crusade.

Andronikos I initiated a reign of terror, executing numerous aristocrats and officials he suspected of disloyalty. His purges weakened the Byzantine nobility and military leadership, creating widespread fear and instability within the empire.

Andronikos I was overthrown by a popular uprising in Constantinople led by Isaac II Angelos. He was captured while trying to flee, and the mob subjected him to three days of torture, including having his hand cut off and an eye gouged out, before he was killed in the Hippodrome.

Following the Umayyad conquest of the Visigothic Kingdom, Pelagius was elected as the first king of the Asturian kingdom by local nobles. This act formalized the Christian resistance and established a new political entity in northern Iberia.

Pelagius led a small force of Asturian and Visigothic rebels against an Umayyad army at Covadonga. The Christian victory is traditionally considered the beginning of the Reconquista, establishing the Kingdom of Asturias as a center of resistance against Muslim rule in Iberia.

After Covadonga, Pelagius expanded and consolidated Asturian control over the Cantabrian mountains and adjacent territories. He established a defensive buffer zone against Umayyad raids, securing the survival of the nascent Christian kingdom.
