The manga series Kingdom is written and illustrated by Yasuhisa Hara. In January 2006, the manga debuted in an issue of Weekly Young Jump seinen manga magazine. The succeeding chapters are still being serialized weekly in the magazine. The first tankōbon volume was released by Shueisha in May 19, 2006; as of April 17, 2015, thirty-eight volumes have been released.
The story of Kingdom is a fictional adaptation of the Chinese history period known as the Warring States period, which ended in 221 BC when Ying Zheng, king of Qin, succeeded in conquering the other states and unifying China.
Several of the characters are based on historical figures. Many times characters will take the names of people in history, and other times they will have completely different names. Often times this is a result of Japanese Kanji borrowing from Chinese characters, meaning that there are some Chinese names that have no equivalent characters in Kanji. For example, Ou Ki's (王骑), name is a slightly altered version of Wang Yi, 王齮, because the last character of his name, 齮, does not exist in Kanji. There are many instances of characters being derived directly from historical figures i.e. Ei Sei is based on Ying Zheng, while his half-brother Seikyō is based on Chengjiao, and his father and grandfather are based on King Zhuangxiang of Qin and King Zhaoxiang of Qin. Ryo Fui is inspired by Lü Buwei. His supporters Shōheikun and Ri Shi are based on Lord Changping and Li Si, and the Mō family (Mō Bu, Mō Gō, Mō Ten, Mō Ki) is based on the Meng family (Meng Wu, Meng Ao, Meng Tian, Meng Yi).
Kingdom was the grand prize winner for the Tezuka Osamu Cultural Prize in 2013 with one judge commenting, "I can't remember the last time I read nearly 30 volumes (of a manga title) in a row feeling this excited." 
The manga also earned a Guinness World Record on December 12, 2012 for Manga written by the most people. The record was due to its "Social Kingdom" campaign in which fans and other artists were given the task of redrawing the entire 26th volume. Participants included manga creators Eiichiro Oda (One Piece), Masashi Kishimoto (Naruto), Hirohiko Araki (JoJo's Bizarre Adventure), as well as voice actors and fans.
