Amalthia Calderon (born 2??? - died 2557) was Protector after Amanda Calderon, relationship unknown. She had at least two daughters: Caterina Calderon, firstborn and Ariana Calderon. Amalthia has the singular distinction of being the first Periphery leader to initiate military action against an Inner Sphere nation. Ariana's War began after Almathia's daughter Lady Ariana Calderon was murdered by her husband Chancellor Kalvin Liao in 2527. Amalthia ordered the Taurain Navy to conduct punitive raids aginst the Capellan border worlds lasting until 2528. 
She died in 2557 and was succeeded by her daughter Caterina.
While no birth date for Amalthia are given, some inferences can be made. Amanda Calderon was the only Calderon left after her father's death, so Amalthia was most likely a daughter or granddaughter, rather than a cousin. Furthermore it is doubtful that a nation who hated the Inner Sphere as much as the Taurians did would allow their future rulers to be born of one!
