Quick Summary

Giampaolo Baglioni was an Umbrian noble and a skilled condottiere (mercenary captain) who dominated Perugia between 1488 and 1534. The Baglioni family was known for its fierce nature and involvement in the political and military struggles of central Italy. Giampaolo emerged as the sole leader of Perugia after a violent family feud in 1500, known as the "great betrayal". He later left administrative duties to pursue his military career, but he and his cousin Gentile retook Perugia after being forced to flee. Giampaolo's life ended when he was lured to Rome and killed by order of Pope Leo X. The Baglioni family continued to provide military captains until their banishment from Perugia in 1534.1
