The Magonids were a political dynasty of Ancient Carthage from 550 BCE to 340 BCE. The dynasty was first established under Mago I, under whom Carthage became preeminent among the Phoenician colonies in the western Mediterranean. Under the Magonids, the Carthaginian Empire expanded to include Sardinia, Libya, and for almost a decade much of Sicily.
Nature of Magonid rule
Leading experts on Carthage have been skeptical as to whether it is even possible to reconstruct the internal history of Carthage and this needs to be borne in mind in relation to the Magonids. Mago and his successors probably ruled less as kings but rather more like tyrants or political strongmen. Diodorus, however, describes them as kings according to laws which implies a legal procedure not a naked seizure of power and Herodotus tells us that Hamilcar I was "king by valor" implying selection not hereditary succession.
In 480 BCE, following Hamilcar I's death, the King lost most of his power to an aristocratic Council of Elders. In 308 BCE, Hannonian Bomilcar attempted a coup d'état to restore the monarch to full power, but failed, which led to Carthage becoming in name as well as in fact a republic.

- Hamilcar I led the expedition to Sicily of 480 BCE 
- Hanno The son of the Hamilcar who was killed at Himera in 480 BCE. It has been conjectured that he was Hanno the Navigator.
- Himilco I (in Sicily) 460-410 BCE
- Hannibal I Grandson of Hamilcar and led the response to Segesta's call for help in 410 BCE 
- Himilco II Laid siege to Syracuse 396 BCE.

With the arrival of Mago, Carthaginian foreign policy appears to have changed dramatically. If previously Carthage had tentatively colonized the island of Ibiza on its own, it now took the lead, establishing itself firmly as the dominant Phoenician military power in the western Mediterranean. Although it still remained an economic dependent of Tyre, it now acted increasingly independently.
Mago was succeeded by his son Hasdrubal I. The next successor was Hamilcar I, the son of Hasdrubal's brother Hanno. Carthage, always trying to rid itself of its opponent, the Greeks, might even have entered into an alliance with the Persian Xerxes (the accounts are unsure) in order to defeat the joint foe. Herodotus tells that it was believed that the decisive battle of Himera between Carthaginian and Greek forces on Sicily took place on the very same day that the Greeks met with the Persians in the famous battle of Salamis in 480 BCE in Greece itself. But the Greeks were victorious in both battles and Hamilcar met his death at Himera.
After Hamilcar's death, the dynasty continued with Hamilcar's son Hanno II 'the Navigator' up to 440 BCE, under whom a large part of Carthage's African dominions were conquered and more of the Atlantic coast of Africa was explored and settled. Great advances were also made in African inland trade. Meanwhile, Carthage appeared to make an effort in keeping itself out of any new wars on Sicily.
This peace and newly acquired vast trading empire also helped rebuild the Carthaginian military forces. By 410 BCE Hannibal I (son of Gisco and grandson of Hamilcar) was the king of Carthage. He immediately set out on a new campaign in Sicily, which in 409 BCE ended in the utter destruction of the city of Selinus, ally of the powerful Greek city state of Syracuse. Hannibal achieved true notoriety with the sheer destruction he wrought and with the cruelty with which he slaughtered thousands of prisoners.
It was at the siege of the Greek city of Agrigentum that an epidemic swept through the Carthaginian camp which killed Hannibal. Hannibal's cousin Himilco II (son of Hanno the Navigator and grandson of Hamilcar) now assumed the reins of power of Carthage. He was only formally crowned king in 396 BCE, but this most likely means that a Carthaginian king could only be installed in the city of Carthage itself and so he had to wait to receive his title formally until he returned home from Sicily.
He spent his time on Sicily in an on-and-off war with the great Syracusan tyrant Dionysius I of Syracuse until in 396 BCE he was disastrously defeated, fleeing Sicily with Carthaginian refugees whilst abandoning his remaining mercenary troops to be slaughtered by the victorious Greeks. Himilco later committed suicide.
Mago II, another member of this family inherited the title of leader at first. His first task was to try and quell a Libyan revolt which came close to overthrowing Carthaginian rule altogether. Thereafter he set out to Sicily again and later even to southern Italy, to occupy himself with Dionysius. What Mago II lacked in military ability he made up for with diplomatic skill. But finally he fell in the Battle of Cronion (378 BCE) in southern Italy against the Syracusan army. Finally, Carthage and Syracuse agreed a peace.
In 480 BCE, following Hamilcar I's death, the King lost most of his power to an aristocratic Council of Elders. In 308 BCE, Hannonian Bomilcar attempted a coup d'etat to restore the monarch to full power, but failed, which led to Carthage becoming in name as well as in fact a republic.
