The Roble Holy Kingdom, usually simply referred to as "The Holy Kingdom," was founded about 200 years ago, not long after the Evil Deities' reign of terror had ended. It is marked haphazardly on maps of the New World. Its land is divided into north and south halves by the sea, but the halves are not completely separate; rather, a gigantic bay, 200 kilometers long and 40 kilometers wide, made its geography look like a U turned on its side. For this reason, some refer to them as different nations; the "Northern Holy Kingdom" and "Southern Holy Kingdom." The Holy Kingdom's national hero is said to be a Valkyrie Knight, wielding a sacred blade.
Abelion Hills & Great Wall
The Holy Kingdom is neighbored by the Abelion Hills, which are inhabited by all kinds of demi-human tribes who are constantly warring with one another. In order to prevent themselves from being invaded and getting caught up in their wars, the Holy Kingdom invested a great amount of time and resources to build a wall along its border to keep the demi-humans out; this would become known as the 100,000-kilometer-long Great Wall.
However, despite all of these defensive measures, the Holy Kingdom still faces invasion from time to time. The greatest of these attacks came during the period known as the "Long Rain" when a race known as the Srush managed to climb over the wall and head deep into the Holy Kingdom's territory. While they would eventually be driven back, this came at the cost of several losses of the Holy Kingdom's villages.
The constant demi-human attacks caused many nobles to grow paranoid, leading to the passing of a law to conscript all of the Holy Kingdom's citizens.
After Calca Bessarez became the Holy Kingdom's first female monarch, southern nobles protested against her being chosen over her elder brother, Prince Caspond, even though he had willingly given up his claim to the throne. They accused her of being in a secret relationship with High Priestess Kelart and Paladin Grandmaster Remedios, which she denied. In the end, the South did not escalate matters further and a full-scale confrontation was averted, but only because the North and South were equally matched in terms of military power.

The Paladin of the Holy Kingdom Arc
One of the fortresses along the Great Wall was attacked by an army of demi-humans led by the demon known as Jaldabaoth. He single-handedly destroyed the fort along with a section of the wall using a single spell, killing many soldiers in the process. Afterward, the demi-human army marched through the opening in the wall into the Holy Kingdom.
News of the wall being breached spread quickly and Holy Queen Calca gave a mobilization order to the entire nation. With the demi-human army heading towards the city of Kalinsha in the Northern Holy Kingdom, the plan was for the Northern Holy Kingdom Army to hold out until the Southern Holy Kingdom Army could arrive. However, the demi-humans arrived sooner than expected with Jaldabaoth attacking the city by himself. In response, the Holy Queen rallied her personal forces and faced the demon. Unfortunately, they were ultimately no match for him and the Demi-Human army successfully conquered Kalinsha, with the Holy Queen being taken as a prisoner and later killed.
Afterward, the demi-human army moved on to conquer most of the North, with citizens being taken to prison camps for experimentation. However, when they attempted to invade the Southern Holy Kingdom as well, their forces were finally halted by the Southern Army at the border. On the other hand, the Southern nobles made no attempts to aid the North, likely intending to use the situation to their political advantage.
To retake the North, the remnants of the Northern Army founded the Holy Kingdom Liberation Army. In reality, however, they were merely a guerrilla unit and desperately needed aid. They, therefore, sent a delegation to the Re-Estize Kingdom but were turned down by everyone they approached. The delegation thus traveled to the Sorcerer Kingdom in hopes of acquiring Momon's support, who had defeated Jaldabaoth before. Unfortunately, the Sorcerer King refused to lend him to them and instead struck another deal; he would secretly travel to the Holy Kingdom and aid them in exchange for the rights to take control of Jaldabaoth's Demon Maids.
Upon returning to the Holy Kingdom, the Liberation Army attacked Jaldabaoth's prison camps and freed the citizens. They then proceeded to liberate the city of Loyts upon learning that the next in line to the throne, Prince Caspond, was being held there. After being rescued, the prince assumed command and ordered the Liberation Army to stay in the city to fight off any demi-human force sent to recapture it. This backfired, however, as the said force was 40,000 strong. The Liberation Army put up a stiff resistance but were ultimately overpowered by sheer numbers. In response to this, the Sorcerer King personally took to the frontlines and single-handedly defeated the Demi-Human force, allowing the city to remain free.
Victory was short-lived, however, as in response, Jaldabaoth personally traveled to Loyts with his Demon Maids to face the Sorcerer King. Upon arriving, the demon handed over Holy Queen Calca's corpse, which had been damaged to the point resurrection had become impossible. He went on to combat the Sorcerer King in an isolated area away from the Liberation Army. Despite putting up a fierce fight, the Sorcerer King claimed to have already used up a vast amount of mana and was seemingly beaten by Jaldabaoth. However, Jaldabaoth had also been heavily injured and decided to retreat without finishing off the Liberation Army first.
With the loss of the Sorcerer King, the Liberation Army decided to focus on defeating the Demi-Human army, ending the siege on the North. Fortunately, they were approached by a race known as the Zern, who were planning to rebel against Jaldabaoth, and a deal was struck; if the Liberation Army rescued their prince, the Zern would help retake Kalinsha. They were also joined by one of Jaldabaoth's Demon Maids, Shizu, who claimed to be controlled by the Sorcerer King and ordered to aid his bodyguard, Neia Baraja. The Liberation Army thus decided to send Shizu and Neia to rescue the Zern's prince, which they successfully did. With the Zern's help, the Liberation Army was able to retake Kalinsha with minimal casualties.
The liberation of Kalinsha convinced several Southern nobles to aid the Liberation Army, hoping to still get some spoils from the conflict. Combining their forces, they marched on the city of Prart and initially had the upper hand against the city's occupiers, until Jaldabaoth personally took to the battlefield and single-handedly turned the tide. However, the Liberation Army was saved by a Demi-Human army led by the Sorcerer King, who was alive and had conquered the Abelion Hills. The Sorcerer King and Jaldabaoth then once again faced each other and the Sorcerer King, now at full strength, slew the demon.
In the aftermath, the Liberation army rooted out most of the remainder of the Demi-Human Alliance and retook the capital of Hoburns. The Sorcerer King going out of his way to save their nation had left a big impression, causing him to gain a huge following. With the passing of Holy Queen Calca, Prince Caspond was to become the next Holy King. Unbeknownst to the public, however, the prince had been replaced by a doppelgänger serving Demiurge and is currently working to destabilize their nation even further.
The Holy Kingdom is a highly religious country, though not as much as the Slane Theocracy. Due to a large number of paladins integrated into the Holy Kingdom's society, a majority of the population share their disdain for the undead and also to the demi-humans. In addition, demi-humans seem to face a lot more prejudice due to the Kingdom's history.
The Holy Kingdom appears to be a mostly male-dominant society, especially in the Southern Holy Kingdom. However, in recent years, women have started to gain more influence; Calca Bessarez as the Holy Kingdom's first female monarch, Remedios Custodio as Grandmaster of the Paladin Order and Kelart Custodio as High Priestess. While the Northern Holy Kingdom approved of women taking on leading roles in their society, many nobles from the Southern Holy Kingdom were upset about these changes. However, these progressive changes were effectively undone following Jaldabaoth's siege, due to both Calca and Kelart being killed in the conflict and Remedios being demoted after she proved to be an ineffective leader.
Aside from that, Magic Casters in the Holy Kingdom were generally priests. While they could make some magic items, precious few of them were made to improve the quality of life. In that aspect, the Re-Estize Kingdom was superior to the Holy Kingdom.
The Holy Kingdom also seems to worship the Four Great Gods, as its paladins are known to frequently visit their temples. Currently, a popular cult is being developed by Neia Baraja, and the other people rescued by the Sorcerer King, dedicated to Ainz Ooal Gown.
Prior to and at the start of the Demi-Human Alliance invasion, the Holy Kingdom is a monarchy initially led by the Holy Queen. However, during and after the war with the Demi-Human Alliance, the monarchy lost its Queen among the casualties and was now being led by Holy King. Before Calca came into power, all the Holy Kings until now have been mainly males who were the ones ruling over the country. As a highly religious country, the temple has some influence over the government, though not as much as in the Slane Theocracy. Not only that, but the Holy Kingdom also has nobles who hold some political influence.
While the churches were under the Holy Queen's control, its government policy was not to bestow a title of Nine Colors on one of their numbers in order to avoid problems with the balance of power.
Although it is a country established with religion as its foundation, it is not the same as Slane Theocracy as the order is maintained through the cooperation between the Temple and the Holy King.
Like the land itself, the Northern and Southern Holy Kingdoms appear to be mostly isolated from one another, with the only thing uniting them being the monarch. After Jaldabaoth conquered most of the North, the South was able to maintain its governmental structure just fine without the monarch.
Since the Holy Kingdom's territory was stretched around the north and south edges of a central bay, any mobilized forces would naturally be formed into two armies -- the Northern Holy Kingdom Army and the Southern Holy Kingdom Army. The armies each have their own important locations which are the city of Kalinsha in the north, and the city of Dibonei in the south.
Due to the demi-humans that reside in the Abelion Hills being a constant threat to their nation, the Holy Kingdom built the Great Wall which is regularly patrolled by several units. However, due to the limited population of the country and the large scale to monitor it, the Holy Kingdom's military conscript their citizens when they reach a minimum age to join. Every citizen who is physically capable must take part in the militarily, regardless of gender. For instance, boys that reach the required age are allowed permission to carry weapons would be enlisted in the military by the country.
After spending a certain amount of time being trained, they would be assigned to sentry duty on the wall. If the worst were to happen such and the wall is breached, it is even possible for the ruling monarch to mobilize the entire nation as a drastic response against incoming invaders. The hope was that the country's own citizens would become the manpower with which to protect their land in case the demi-humans crossed the wall.
All of the Holy Kingdom's villages of a certain size have also been fortified. This gives the villagers enough fighting power to hold out for the regular army to arrive and also allows said villages to serve as military outposts. Thus, the villages of the Holy Kingdom were far better protected than those of other countries, and they could also function as military bases.
Their holy church has highly trained priests and disciples who are capable of using holy magic of an average up to third tier and some even higher than that. As well as they are capable of using summoning Angels too.

Due to being almost completely cut off from other human nations by the Abelion Hills, the Holy Kingdom is a mostly isolated country. However, there's still one open land route as well as sea travel, causing there to still be some communication with other countries and the Holy Kingdom is willing to ask for their aid if necessary. The Holy Kingdom's citizens certainly want their nation to be part of the international stage. Unfortunately, they ultimately can't spend the manpower as they need to constantly focus on keeping the demi-humans out.
The Holy Kingdom is under constant threat of being invaded and/or getting caught up in one of the many wars of the demi-human tribes residing in Abelion Hills. In order to prevent this, the Holy Kingdom build the greatest defensive structure in the New World: the Great Wall.
The relationships between the citizens of the Holy Kingdom and the demi-humans are extremely bad. The Holy Kingdom has no desire to negotiate with them. However, when an army of demi-human tries to invade, they sometimes pretend to; this is in order to draw out their leaders and assassinate them.
After the Sorcerer King took control of the region and formed his own demi-human army to combat the Demi-Human Alliance, the relations between the Holy Kingdom and the Abelion Hills seemed to have improved slightly. Despite this, however, the Sorcerer King assumed there were still some lingering resentments and thus made sure to keep the demi-humans away from the citizens.
Upon being informed about the massacre at the Katze Plains and the founding of the Sorcerer Kingdom, the Holy Kingdom chose to accept the nation as an independent sovereign state and allow free travel between its citizens. However, due to the Temple's prejudice towards the undead being highly indoctrinated into the Holy Kingdom's society, many citizens viewed the Sorcerer Kingdom as a threat second only to demi-humans and urged the government to send troops to retake the captured city of E-Rantel. Unfortunately, the Holy Kingdom was unable to do so as they need to focus on defending their own borders before focusing elsewhere.
After Jaldabaoth laid siege to the Northern Holy Kingdom and the Re-Estize Kingdom turned down the Holy Kingdom Liberation Army's requests for aid, envoys traveled to the Sorcerer Kingdom to request for Momon's aid. Unfortunately, the Sorcerer King refused to lend him to them and instead struck another deal; he would personally aid them in return for the rights to take control of Jaldabaoth's Demon Maids. Despite this, however, the Liberation Army's higher-ups secretly planned to have him and Jaldabaoth to kill each other.
The Sorcerer King proved to be vital in the liberation of the Northern Holy Kingdom, causing the outlook of towards both him and his nation to slowly change. Even when they were deprived from his physical presence, when he was assumed dead, the Liberation Army continued to profit off him in the form of CZ and Neia Baraja. While the Liberation Army's higher-ups were concerned about his growing influence, his supporters had already grown too strong. After the Sorcerer King returned and liberated the Northern Holy Kingdom, the citizens saw him as a hero and began preaching his ideals that strength is justice as a religion.
Since the only land route out of the Holy Kingdom leads to the Kingdom and they share a sea border as well, the two nations naturally trade with each other. However, following the massacre at the Katze Plains, the opinions of several Southern Nobles towards the Kingdom soured, believing the nation will be assimilated by the Sorcerer Kingdom sooner or later.
After Jaldabaoth conquered most of the Northern Holy Kingdom, the Holy Kingdom Liberation Army send an envoy to the Kingdom to request for support in reclaiming their nation. Unfortunately, everyone they approached turned them down due to various reasons, but mostly because the Kingdom was still recovering from the massacre at the Katze Plains. The envoys thus deemed the Kingdom to be a lost cause and moved on to the Sorcerer Kingdom.
After the founding of the Sorcerer Kingdom, many citizens wanted to form an alliance with the Theocracy to destroy the non-human nation. Due to religious differences, however, an alliance will be difficult.
In the Web Novel, it is stated that the Holy Kingdom have once maintained connections with the Slane Theocracy, but due to the encroaching warring demi-human tribes, the latter lost contact.
