The Sassanid Empire was centralized, and the king was called the "Great King" or "King of Kings"; The royal power was theoretically unlimited, but in practice it was subject to the religious and secular aristocracy.

Under the king, there was a council of royals, and the council was composed of members of the clan, high priests, and high nobles.

Under the Council of the Emperor is the central administration, and the supreme head of the central administration is the prime minister (known as Hazarpat, also known as the Great Vramtar), and under the prime minister there are officials such as administration, taxation, and treasury.

There was also a commander-in-chief in charge of the army, called Iranian Xue Bobo.

The Sassanid dynasty elevated Zoroastrianism (Zoroastrianism) to the status of state religion and appointed a high priest to hold Zoroastrian power.

Zoroastrian priests and military aristocrats owned large amounts of land, and the kingdom gave the priests the right to tithes the taxpayers.

Zoroastrian priesthood, military aristocracy, and slave-owning groups were the basis of the Sassanid dynasty.

The Sassanid Empire, like the Sabbath Empire, divided the country into many vassal states, provinces, and regions, with 27 provinces at the time. Provincial governors were appointed by the king, and nominally, they were subordinate to the imperial court, but in practice some provinces were governors appointed by local nobles and had a certain degree of independence.

At this time, there was unfortunate news that the provinces of Isfahan and Fars had been conquered by the Han Chinese.

Isfahan was one of the oldest cities of the Sassanid Empire, founded in the 4th and 5th centuries BC and was a major military and trade powerhouse of the Sassanid Empire. The name "Isfahan" is derived from the Persian word "spahan", which means army, and in ancient times it was a place where troops were assembled, hence the name. As an important town on the Silk Road, it was also a hub for trade between the East and the West, with merchants and guests from all over the world, and there is a proverb that "Isfahan is half the world", reflecting the prosperity and far-reaching influence of the region at that time.

The province of Fars was even more significant to the Sassanid Empire.

King Ardashir I was born into a prominent family in the province of Fars, and his grandfather, Sasanian, was a priest of the temple of Anahit, from which the dynasty was named. Before raising troops to establish a dynasty, King Ardashir I was the governor of the province of Fars in the Sabbath Empire, where he started his home and where his family was based.

The two places were conquered by war, which was a heavy blow to the Sassanid Empire, which made morale low, and the nobles lost confidence in the war, after all, it was their first time fighting the Han Chinese; And the powerful nomadic empire, the Kushan Empire has already submitted to the Han people, and the strength of the Han people is too strong.

Soon after, the emissaries who had entered the city of Susa for negotiations returned, bringing even more unfortunate news that made everyone unwilling to accept this reality.

At this time, the military aristocracy and the slave-owning group were divided into two factions due to differences of opinion.

One is the resistance faction, because their homes and territories have been plundered by the Han Chinese, and only by defeating the Han people can they regain their lost wealth and avenge their families.

The other faction was the capitulation faction, which insisted on overthrowing the emperor at that time and accepting the rule of the Han Chinese; They believe that the country of the Han people is too far away from here, and the officials sent are only a few after all, so even if the Han people rule here, they cannot do without these nobles, and the Han people will still use them to manage the country, and they are still free.

More importantly, their homes have not been plundered, and they hope to protect the safety of their families and property after taking refuge with the Han Chinese.

Now the Han people are divided into two parts, both of which are very strong, only the strength of the kingdom can resist one of them, if the army is divided, it may be broken by each one, if only one of the Han people is besieged, the other Han people can loot unscrupulously, and sooner or later they will plunder their homeland.

The Han Chinese continued to plunder, and now they were not allowed to think too much, and they had to make choices as soon as possible to protect themselves. And the plundering of the Han people will inevitably cause the weakening of the strength of the Sassanid Dynasty, even if the Han people can't lead here, slap their butts and leave, but what they leave behind is a mess, they will also lose their strength greatly, and they will be easily wiped out by the Romans, and the consequences for them will be more difficult to accept, so it is better to surrender to the Han people.

The two sides are very resolute in their antagonism, and this is related to their fate hereafter.

The two sides are on the verge of breaking out.

The king was supported by the resistance and ecclesiastical forces, and he was not willing to surrender or die.

At present, there are still a small number of looted areas, so the strength of the surrender faction is greater. In order to strengthen their own strength, the capitulation faction has sent people into the city to contact the Han Chinese.

Ma Gui was very happy to see them fight, he thought, after establishing his dominance in this land, he could slowly deal with these surrenderers and take full control of the whole country, so he gladly accepted the surrender of the capitulation faction.

However, Ma Gui vetoed the proposal to unite against the resistance, fearing that there would be deception, so he promised them that after they defeated the king's army, the Han army would go out of the city to join the battle.

Now that the Han Chinese accepted their surrender and eliminated their worries, the capitulators had to show the courage to defeat the king's army in one fell swoop, and with great results, they were able to gain a place in the New Kingdom, so the morale of the capitulating nobles and slave owners was greatly increased.

The Sassanid Dynasty overthrew the Sabbath Empire, and the founding of the country was only more than ten years old, and many nobles were very big nobles when the Sabbath Empire was in Sabbath, and they did not have much loyalty to the Sassanid Empire, and their allegiance to everyone was the same, as long as they could maintain their status.

In order to reduce resistance, the capitulationists bribed the king's bodyguards, promising them substantial benefits.

Most of these guards came from the province of Fars and were loyal to the king, but now that their homes have been plundered, they have lost their wealth and their families, so to speak, and if they join the new forces and have a lot of wealth, they can still marry wives and have children, and rise quickly.

With the assistance of these guards, the capitulationists were more confident.

War broke out suddenly in the dark of night.

The capitulation faction was well prepared and morale was high.

The Resistance responded in a hurry, lacking command.

The guards took advantage of the chaos to kill the king, Hazarpat, priests and others, and wiped out the high-ranking officials of the dynasty.

Having lost the object of command and allegiance, the resistance faction fell into disarray, fought on its own, even killed each other, unable to organize an effective counterattack, and was defeated by the capitulation faction.

The carnage continued until dawn, by which time the winners and losers were decided, and the resistance was left with few to surrender and the war ended.

The Sassanid Kingdom, which had been founded for less than two decades, collapsed.

The capitulationists immediately sent men to the city of Susa to report the good news.

Ma Gui and the others were overjoyed, but they didn't expect to destroy the powerful Sassanid Kingdom so simply.

The country cannot be without a king for a day, and Gao Shun is not here, so Ma Gui asked Sun Cheng to replace his son on the throne as king.

Gao Shun had previously decided to make Sun Cheng's second son the king after the destruction of the Sassanid Kingdom, and Sun Cheng had to ascend the throne early and wait for his son to arrive.

The name of the country is "An", which is the first word of the Rest Empire, which also represents peace.

Sun Cheng then demanded that the surrender faction clean up the battlefield as soon as possible, and sent an envoy to Fars Province with a handwritten letter from him and Ma Gui to welcome the Han army, and let the warships waiting on the Persian Gulf return to Xiliang to inform Gao Shun and Gao Wei and others.

Subsequently, Sun Cheng announced at Ma Gui's request that all the resistance factions would be reduced to slavery; All the weapons and armor of the dead and wounded on the battlefield were returned to the imperial court; The spoils of war went to the imperial court.

After returning to Taixi to seal the city and officially ascend the throne, he will be rewarded according to his military exploits.

The surrenderers were overjoyed, the Han Chinese kept their promises, stopped plundering, their status, their families, and their wealth were safe, and their choice was correct.
