Kingdom (Korean: 킹덤) is a South Korean period horror television series, created and written by Kim Eun-hee and based on the webtoon series The Kingdom of the Gods (신의나라:버닝헬) by writer Kim Eun-hee and artist Yang Kyung-il. As Netflix's first original Korean series, it premiered on January 25, 2019. It stars Ju Ji-hoon, Bae Doona, Ryu Seung-ryong, Kim Sang-ho, Kim Sung-kyu, and Kim Hye-jun. The first season, and the first episode of the second were directed by Kim Seong-hun, with Park In-je directing the remainder of that season.

Set at the start of the 17th century, three years after the end of the Imjin War, Kingdom takes place in a fictional, medieval-inspired Joseon (modern-day Korea) and blends political thriller and elements from zombie horror. The story follows Lee Chang, the Crown Prince of Joseon, who attempts to investigate the mysterious illness recently afflicting the King, only to find himself caught in the middle of a deadly epidemic ravaging the kingdom. While trying to save the Kingdom from the plague, he must also stop his political opponents from seizing the throne.

The series was positively reviewed, and renewed for a second season which was released on March 13, 2020. A special feature-length episode of the series, titled "Ashin of the North", was released on July 23, 2021, presenting a focus on the supporting character played by Jun Ji-hyun. The episode acts as a sidequel to the second season of Kingdom and explores the backstory of Ashin, the mysterious character Lee Chang's group encountered on their journey north to discover the origins of the infected.

It has been ten days since the King of Joseon became deathly ill from smallpox. The only ones allowed to see him in his palace at the Hanyang are the Chief State Councillor Lord Cho Hak-ju, leader of the Haewon Cho clan, and his daughter, Queen Consort Cho, who is pregnant with the King's child. Seizing power, the Haewon Cho arrest and torture 89 scholars implicated in a treasonous plot to depose the King and replace him with his son, the Crown Prince Lee Chang, who is the child of the King with a concubine and thus a less legitimate heir than the unborn child of the Queen Consort. The ringleader of the conspiracy, Lee Chang himself, becomes suspicious of his father's condition and sneaks into the palace to investigate, but is caught by Cho Beom-il, the son of Lord Cho Hak-ju and brother of the Queen Consort who is a commander of the Royal Army. Lee Chang decides to flee the palace with only his trusted bodyguard Mu-yeong to track down the royal physician, and Beom-il and a platoon of soldiers are dispatched to find and arrest him. Meanwhile at the city of Dongnae, ill patients are overflowing Jiyulheon, Lee Seung-hui's clinic and there is not enough food to feed them all. The royal physician returns, with the corpse of his assistant Dan-i who was killed by an unseen monster in the king's palace. One of the patients, Yeong-shin, uses Dan-i's flesh in a stew to feed the patients and is discovered by Seo-bi, Seung-hui's assistant. All of the patients die, but are soon resurrected into flesh-eating monsters.

Investigating, they discover the corpses of the patients, which are then brought to Dongnae for autopsy and funeral rites. Lee Chang and Mu-yeong learn from an herbalist in the city that Seo-bi survived the incident and track her to the Frozen Valley, a region home to what is called the resurrection plant. Meanwhile, Yeong-shin returns to Jiyulheon to find the corpses missing and hurries to Dongnae, where he is arrested by the local magistrate, Cho Beom-pal, another member of the Haewon Cho clan, under suspicion of killing the patients. Seo-bi explains to Lee Chang and Mu-yeong that the patients transformed into monstrous cannibals that apparently cannot be killed and are nocturnal, becoming active when the sun sets. The royal physician, Lee Seung-hui kept a journal documenting these changes and the events at the royal palace, which could be used as evidence. Lee Chang returns to Jiyulheon to find this journal, while Mu-yeong and Seo-bi travel to Dongnae to warn the locals. Instead, Seo-bi is arrested and imprisoned with Yeong-shin. When night falls, the corpses of the patients awaken and attack. At Jiyulheon, Lee Chang is confronted by Beom-il, and the two duel.

When the sun rises, the zombies become dormant, stuffing themselves into confined spaces to avoid sunlight. Revealing himself, Lee Chang assumes command of the local soldiers and orders the zombies to be burned and an immediate quarantine of Dongnae to take place, but there are not enough surviving soldiers to carry out his orders. Reading Seung-hui's journals, Lee Chang learns that after the king perished from smallpox, Lord Cho Hak-ju ordered the royal physician to treat the corpse with the resurrection plant. However, when the king bit Seung-hui's assistant Dan-i, he merely fell ill and died instead of transforming into a zombie. Seo-bi attempted to find another of the resurrection plant in the Frozen Valley, but without the plant a cure for the infection cannot be found. Vowing revenge against the Cho clan, Lee Chang resolves to travel to Sangju to meet with Lord Ahn Hyeon, a governor and retired war hero with ties to the royal family. At the same time, the Chief Scholar Kim Sun, part of the conspiracy to depose the king, becomes suspicious of the king's disappearance and also attempts to contact Lord Hyeon.

With Lord Hyeon's backing, Lee Chang assumes command of Sangju, and draws up a battle plan to fight the infected by fortifying defensible locations surrounded by water, which they know is a weakness of the zombies.

In Hanyang, the pregnant women gathered by the Cho family begin to give birth, as it is revealed that the Queen Regent is not actually with child.

As they prepare to leave and rest for the day, the infected begin to arrive, as Seo-bi realizes that the zombies are not actually nocturnal, and their activity was determined by temperature instead.

13	"Ashin of the North"	Kim Seong-hun	Kim Eun-hee	July 23, 2021 (2021-07-23)
During the Imjin War, Ashin, a member of a Jurchen tribe living in northern Joseon, becomes the only survivor of her village of Seongjeoyain after it is massacred by the outlying Jurchen tribe of Pajeowi. Seeking revenge, she trains in a Korean military garrison while being tasked with menial jobs and is sexually abused by the soldiers. After finally being ordered to spy on the Pajeowi camp, she comes across her limbless father Ta Hab who, prior to the massacre, had been ordered by the Joseon commander to speak with the Pajeowi leader Ai Da Gan in order to dissuade them from invading after several Pajeowis were found brutally murdered in the Pyesa-gun forest. Horrified at his state, she kills him in an act of mercy. After setting the Pajeowi camp on fire, Ashin returns to her base and uncovers the commander's papers revealing that the villagers of Seongjeoyain were framed as the culprits of the Pyesa-gun killings in order to cover-up the culpability of Cho Beom-il, a high-ranking member of the Haewon Cho clan. In retaliation, Ashin kills several Joseon soldiers as they sleep and uses the resurrection plant to reanimate them as zombies who rampage around the camp while she kills survivors with her arrows. Using the last soldier as bait, she attracts the zombies together and then burns them, effectively killing everyone in the camp. Ashin returns to Seongjeoyain with a sack. Entering her old house, she is met by her zombified family and neighbors whom she converted using the resurrection plant after the massacre. Having fed them animals for years, she opens the sack and feeds them a live soldier inside. She then vows to wipe out every living thing in Joseon and among the Jurchen to avenge her village and join the undead when she is done. Ashin leaves to meet Lee Seung-hui, the Royal physician at the border in Uiji and sells him the resurrection plant. Afterwards, Ashin encounters Ai Da Gan and his army. As they approach Ashin, she fires an arrow at them.

Production

Development

Netflix approached Eun-hee, after Signal ended its run, to work on a future project that she could helm. After successfully pitching the concept of the show, Netflix agreed to the proposition and committed to a series order announcement. On March 5, 2017, Netflix announced that it had given the production a series order for a first season. Alongside the series announcement, it was confirmed that Kim Seong-hun would direct the series and that Kim Eun-hee would be credited as the writer. Production companies involved with the series were slated to consist of AStory. Even before the release of the first season, Netflix announced that they would be making a second season. Filming for the second season started in February 2019, with Director Park In-je joining the production to direct its second episode and onward. In November 2020, production for a one-off special episode Kingdom: Ashin of the North was confirmed, with season one director Kim Seong-hun returning and Kim Eun-hee reprising her role as screenwriter.

The series overspent the budget, with each episode costing more than $1.78 million. As a result, the first two seasons, which were originally planned to have eight episodes each, were shortened to six episodes.

On January 16, 2018, a crew member of the art team died due to overwork. On March 14, 2019, it was confirmed that in the midst of filming the second season, a staff member in the production team died after a car accident. On January 7, 2021, a castle on the filming set of Kingdom: Ashin of the North caught fire as a staff member attempted to melt the snow using a torch lamp. Parts of the castle were destroyed in the process of extinguishing the fire, and there were no resulting injuries.

Writing

Screenwriter Kim Eun-hee began thinking about the story behind the series in 2011, wanting to reflect the fears and anxiety of modern times through the lens of the historical Joseon period. Originally, the creator thought it would be difficult to portray the story in a television series format, and instead created the webcomic The Kingdom of the Gods alongside illustrator Yang Kyung-il in 2014. While the series is adapted from the webcomic, they do not share much commonality other than their basic concepts.

Whilst working on television series, Phantom and Signal, Eun-hee continued to work on the project but encountered challenges in writing a period piece and securing investments for the project. Born out of an interest to explore opportunities for writing in a diverse range of genres and not limited by conventional choices in storytelling and censorship in publicly broadcast K-dramas, Eun-hee credited the success of Train to Busan, as the turning point for the revitalization of the interest in zombie films in the Korean media space.

In an online interview, Eun-hee stated that politics is integrated to the core of the series, noting that "It's about what politics is. Flawed politics created resentment, and there will be a consequence of gaining the plant that brings dead people to life". She added that the political environment drives many of the decisions, and propels the actions of characters in their journey, highlighting that "If we go deeper and deeper, it all boils down to politics. The pain that comes from politics, the price we have to pay for pain, they are the message that penetrates the series." Eun-hee further spoke about the importance of blending those genres and particularly focusing on the examination of the political elements covered in the series, citing that "politics and the living dead are not separate, but they rather come together as one." Adding to that, Eun-hee commented about the nature of politics, and its role in shaping the world of Kingdom. The series' portrayal of political dynamics of corruption and power highlights the disparity of growing concerns against the bourgeoise, suffering in the midst of a plague. Speaking on the conceptualization of the plague, the creator argued its role in the narrative is to serve as a reflection of the corruption, greed, inequity and injustice committed by the ruling class, using it as a camouflage to usurp the political power to maintain influence in the Kingdom of Joseon.

Eun-hee stated in an interview that she wanted to depict several themes through the use of various narrative devices in the series. She later explained that the theme of the first season was "to tell a story about hunger." Eun-hee further added that she wanted to "portray people who were mistreated by those in power struggling with starvation and poverty through the monsters". Shifting to the second season, the theme of blood was explored to "tell a story about monsters who crave blood and humans who desire a particular bloodline and lineage." Later, Eun-hee noted that a future season of Kingdom will dabble in the exploration of resentment as a theme for the basis of the new story to be told.

After Netflix ordered the special episode Kingdom: Ashin of the North, Eun-hee highlighted that the episode will mark an important bridge between the events of the first two seasons and the third season. In an interview, Eun-hee elucidated further on the reasoning behind the episode, stating that "I decided to go with a special episode because I thought it would be more interesting. We cannot leave out the story of the resurrection plant." She further added that "If the first season served as the cornerstone of the show, Kingdom: Ashin of the North, will be a stepping stone for the third season of Kingdom." In an interview with The Philippine Star, Kim Eun-hee discussed the significance of exploring the concept of Han in the special episode. Whilst the creator began to delve into the idea through the creation of Ashin's character when writing the second season, Kim Eun-hee wanted to further examine the collective trauma, grief and resentment born from the experiences of tragedy in the special episode. The writer expressed her desire in depicting Han in the story, stating that "I always wanted to write a story about the feeling of Han. And in the previous seasons, it's usually focused on the dominating power such as Prince Chang and the established people who lead the story. And then I came to think of the northern part of Joseon and the ones who are actually dominated by these people. So regardless of whether it is Joseon or another country, I think the people who are dominated have that same feeling (of Han)."

Filming

Principal photography for the first two seasons took place on location in Seoul, South Korea, including the Gyeonggi Province and North Gyeongsang Province between 2018 and 2019. Filming for Kingdom: Ashin of the North took place in Jeju Island in 2020.

Casting

Actor Song Joong-ki was courted for the lead role but declined. In September 2017, it was reported that Ju Ji-hoon, Ryu Seung-ryong, and Bae Doona were in talks to star in the series. In November 2019, it was reported that Jun Ji-hyun would star in the second season. After the announcement for the special episode, it was confirmed that Jun Ji-hyun and Park Byung-eun would reprise their respective roles in Kingdom: Ashin of the North. Additionally, it was confirmed that Kim Shi-ah, Koo Kyo-hwan and Kim Roi-ha were cast in the special episode.

Prior to the premiere of the second season, Joo Ji-hoon stated in a Forbes interview, that he signed on to star in the series, due to his faith in the project. He adds that "From the refreshing subject matter to writer Kim Eun-hee's exciting script, direction by director Kim Sung-hoon—and the cast members from season one—all these factors convinced me to continue on the journey to season two". Furthermore, he was excited at the prospect of a new director, joining the series in the second season, commenting that "Park In-je joined us for season two, and the new system of 'making a TV series with people who make films' was fascinating. The intensity is definitely higher compared to filming a two-hour film, but the actors were allowed enough time and room to prepare for filming a season that amounts to six hours, so I had faith in the outcome being of high quality."

In a press conference for Kingdom: Ashin of the North, Jun Ji-hyun revealed her experience of joining the series. The actress stated that "I was a huge fan of Kingdom. When I met with the writer [Kim Eun-hee] in a private setting before I was offered the role, I told her I was willing to even appear as a zombie in Kingdom. I am so thankful that she gave me such a big role." She later stated that after reading the screenplay for the special episode, "I was thrilled at the thought that I could start the big story."

Reception

The first season received critical acclaim from critics and the audience. The review aggregator website Rotten Tomatoes reported a 94% approval rating based on 16 reviews. The website's critical consensus reads, "An enthralling blend of blood, terror, and political intrigue, Kingdom is a refreshing addition to the zombie landscape." The series is praised by critics for its blend of the political thriller, historical drama and horror genres.

Aloysius Low of CNET praised the cinematography of the first season, stating that "shots cleverly linger on certain scenes to draw out the impressive sets, while adeptly tracking the action during sword fights or zombie attacks." Renaldo Matadeen from CBR mentioned in a positive review of the first season, that "Kingdom makes even bolder sociopolitical statements than The Walking Dead does. Sure, the AMC series waxes on about class and elitism, but Kingdom wades deep into governance and the divide between the rulers and the suffering populace." Jonathan Christian from The Playlist complimented the series by adding that "this series is risky programming for people who appreciate the unusual, gory, but imaginative, things in life. Considering the over-saturated state of the market, it is refreshing to see Netflix taking chances." Joel Keller from News AU recommended the first season in their review of the series by stating that "Kingdom dares to show that zombies aren't just a 20th and 21st-century phenomenon, and we applaud that kind of creative storytelling."

While reviewing the first season, Kate Sanchez from But Why Tho? declared in a positive review that "Kingdom offers a period drama, a zombie show, and a tense atmosphere that will keep you watching until you're done with this season. In an over-saturated sub-genre, this show takes common horror tropes and rewrites zombie rules for Joseon Korea in a way that reinvigorates my love of the sub-genre." Michael Pementel from Bloody Disgusting praised the series, stating that "Kingdom is by far one of the most compelling works to come out of the zombie genre" and further adding that "thanks to strong acting, gripping action and drama, gruesome visuals, and an overall powerful narrative, Kingdom is a must watch for horror fans."

On Rotten Tomatoes, the second season reported a 100% rating based on 10 reviews.

Jorge Loser from Espinof wrote that, "Kingdom avoids unnecessary fillers in the story, and leaves a consistency in its spine that makes it worthy." Sol Harris from Starburst praised the second season, stating that it is "a true roller-coaster of a thrill-ride, balancing nail-biting zombie carnage with the sword-based military action of countless samurai movies with a handful of darkly comedic moments that would make Sam Raimi proud." Kevin Lever of Tell-Tale TV gave the second season a very positive review, writing: "the most important thing about Kingdom remains absolutely, undeniably riveting. The political intrigue is certainly exciting when the outbreak is its backdrop, the future of the country at risk when leadership is most needed." He said further that the season, "continues the greatness of the first season and delivers a satisfying, bloody good time." Rafael Motamayor from GameSpot recommended the second season in his review by highlighting that, "Not to be outdone by Game of Thrones, Kingdom also serves as an intriguing courtroom thriller", further praising the narrative, by adding that it "doubles down on the viral aspect of the zombie outbreak, exploring its natural origin, how it spreads, and most frighteningly, how it evolves."

The New York Times named Kingdom one of "The Best International Shows of 2020." Following Netflix's reporting on the considerable success that Kingdom obtained globally after it was made available to stream on their platform service, Eun-hee stated in response that "I could never have imagined the popularity [Kingdom got]. I did my best to make it as Korean as possible because I wanted people to see it and become more curious about Korea."
