In later eras, conquering a tribe or city-state, or forcibly merging two peoples, became an extremely difficult task, requiring several major wars or a long period of assimilation.
However, in the Age of Gods, with Ares's status as a main god, such things were simple. He only needed to issue divine oracles as a god through his spokespersons.
Ares creating his own avatar and acting as his own spokesperson was partly due to habit, and partly because Sparta would become his base against the gods in the future. He had to be hands-on, holding Sparta firmly in his grasp, and not allowing other gods to interfere.
Currently, the Laconia numbered only two to three thousand, and after the Famine, the Dorian were less than a thousand. Therefore, under Ares's command, these two races quickly merged. Ares's divine power avatar directly dispatched two subordinate gods from Olympus to descend and help the Dorian and Laconia expand their city-state. With Zeus's previous command, he also obtained help from Demeter, the goddess of agriculture, to make the Laconia Plain fertile. Soon, the two tribes, now Spartans, settled down in their newly expanded city-state.
After Ares's avatar took control of Sparta, he quickly began to designate management positions and formulate the governing rules for Sparta.
In principle, Sparta worshipped Ares as its patron god, and Ares's elderly avatar was the supreme leader of Sparta. He was the manager of Ares's Temple of War, honored as the High Priest. Under him would be twenty selected individuals, serving as Ares's priests, responsible for Sparta's divine affairs and the selection of Spartan warriors.
Ares retained the Spartan's harsh selection system, which began from infancy. However, under his system, those who failed the selection would not be directly thrown off a cliff by the priests as in the original myth. They would be adopted in other ways, given different education, and trained for other professions besides warriors, such as farmers, herders, fishermen, poets, scholars, blacksmiths, etc., to contribute to Sparta in different ways.
Among these children, if there were any with exceptional Magic Circuit talent, they would be admitted into another organization called the "Council of Sages," specifically responsible for managing matters related to magic and sorcery for Sparta.
As for the children who successfully passed the selection, they would embark on the path of the warrior. Before the age of 7, these children would be raised by their parents, who would carefully cultivate habits in them such as not crying, not being picky eaters, not being noisy, not fearing darkness, and not fearing loneliness.
After the age of 7, these children would be assigned to teams for collective military life. They were required to obey their leaders absolutely, and to enhance their courage, physical strength, and ruthlessness. They practiced running, discus throwing, boxing, fencing, and brawling.
After the age of twelve, while undergoing more rigorous trials, Ares would also dispatch specialized personnel to train them and teach them a new reinforcement system. This was because Ares had previously tried to use his own Magnetic Field Rotation to influence the current rotation of other humans, helping them break through to the realm of the Magnetic Field. However, Gaia seemed to have locked onto him, and this attempt ultimately ended in failure under a mysterious influence.
Considering the planetary inhibitory force's suppression of interdimensional powers, Ares simply taught these children the "Magic Power Propulsion" he had re-created by combining the two. Under the effect of Magic Power Propulsion, their Magic Circuit were stimulated, continuously creating energy in their bodies in the form of magic power, strengthening their physical bodies. Warriors who cultivated to a profound level could even rival the Heroes in combat power.
These children would become Sparta's warriors in the future, serving as the foundation for Sparta's victorious campaigns, unbeatable in a hundred battles.
As for the original leadership of the Laconia and Dorian, Ares also utilized the new system to assign them their respective duties. The Dorian were more skilled in War than the Laconia; in previous battles, the Laconia had also lost to the Dorian. Thus, Ares made the Dorian's leader and his brother, descendants of Agiad and Eurypontid, the Kings of Sparta.
One was responsible for defending the city-state, and the other served as the commander of the army fighting abroad. However, in peacetime, they merely acted as symbols of the Spartan state. Only during War did the dual Kings have the authority to control the army. Furthermore, among the Dorian, five of the most skilled warriors were chosen by Ares as Spartan Ephs, responsible for assisting the Kings in their work.
As for the Laconia, Ares mobilized their original nobles, making them the Elders of Sparta. In peacetime, the Council of Elders would be responsible for managing all aspects of the city-state's normal operation, and all major affairs concerning the city-state would also be voted on by the Council of Elders.
Of course, in the end, whether it was the dual Kings, the Ephs, or the Council of Elders, all had to obey the leadership of the High Priest of the Temple, which meant obeying Ares's leadership.
This system was a slight improvement on Sparta's original operating system, directly applied by Ares. He had considered constructing a more efficient and advanced governance system for these Spartans, but things too far ahead of their time cannot adapt to it. Half a step ahead of the times is genius, but a full step is madness. The current Sparta could only adapt to this small-state, small-population system of Kings plus a Council of Elders.
Under Ares's divine might, the Spartans were also very obedient. Perhaps the blood of soldiers, obeying orders, naturally flowed within these warriors. Soon, Sparta began to operate and develop steadily under this system.
Ares then took the opportunity to ask for help from the gods on Olympus. However, Ares did not ask for their direct help; he merely sought an oath from each of the twelve main gods, excluding Athena, Aphrodite, and Zeus.
He tried to make Demeter swear that the Laconia Plain where Sparta was located would always be fertile, to make Poseidon swear that Spartan ships would never be overturned by waves, to make Hermes guarantee that Sparta's commercial activities would always prosper, to make Apollo swear that Sparta would always be illuminated by light, to make Artemis swear that Spartan hunting would never lack prey, and to make Hera swear that Spartan marriages would always be stable and Spartan procreation always secure.
Apollo and his sister had always had a good relationship with Ares, so they quickly swore the oaths. Hermes, after the incident of stealing cattle, also had a decent relationship with Ares. However, perhaps it was out of an inherent disdain for humanity, even the Sea King and the goddess of agriculture, who usually had a strained relationship with Ares, held their noses and swore the oath out of respect for Zeus.
As for Hephaestus and Hestia, it is unclear what they considered. In any case, when Ares went to them for help, Hephaestus simply waved his hand, arranging for his divine messengers to go to Sparta to specifically train a group of blacksmiths. Hestia, on the other hand, seized the opportunity to ask Zeus if she could directly go to Sparta and settle down among the human hearths, responsible for protecting the hearth fire of the Spartans and indeed all humanity.
And on the day Sparta was completed, Hecate also exchanged her Cerberus to gain dominion over the Underworld region beneath the Laconia Plain from Hades, and then shielded and modified that area with magic.
