Amadeus of the Amidei was a 13th-century friar from Florence who helped establish the Servite Order. Born into the Amidei family, he was one of seven men, known as the Seven Holy Founders, who formed a spiritual bond and dedicated themselves to serving God through intense Marian devotion. Following a shared vision, the group abandoned worldly life to live as mendicant friars. He is recognized as a saint within the Catholic Church for his role in founding this religious order.
