Year 238 (CCXXXVIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Pius and Pontianus. The denomination 238 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
The Three Kingdoms of Cao Wei, Shu Han, and Eastern Wu dominated China from 220 to 280 AD following the end of the Han dynasty. This period was preceded by the Eastern Han dynasty and followed by the Western Jin dynasty. Academically, the periodisation begins with the establishment of Cao Wei in 220 and ends with the conquest of Wu by Jin in 280. The period immediately preceding the Three Kingdoms, from 184 to 220, was marked by chaotic infighting among warlords across China as Han authority collapsed. The period from 220 to 263 was marked by a comparatively stable arrangement between Cao Wei, Shu Han, and Eastern Wu. This stability broke down with the conquest of Shu by Wei in 263, followed by the usurpation of Cao Wei by Jin in 266 and ultimately the conquest of Wu by Jin in 280.
Year 197 (CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus. The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Year 220 (CCXX) was a leap year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Antonius and Eutychianus. The denomination 220 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Year 228 (CCXXVIII) was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Modestus and Maecius.

The Daifang Commandery was an administrative division established by the Chinese Han dynasty on the Korean Peninsula between 204 and 220. It was conquered by Goguryeo in 314.
Gongsun Kang was a Chinese military general, politician, and warlord who lived during the late Eastern Han dynasty. He became a vassal of the state of Cao Wei in the early Three Kingdoms period.
Wei was one of the major dynastic states in China during the Three Kingdoms period. The state was established in 220 by Cao Pi based upon the foundations laid by his father Cao Cao during the end of the Han dynasty. Its capital was initially located at Xuchang, and was later moved to Luoyang.
Gongsun Yuan, courtesy name Wenyi, was a Chinese military general, politician, and warlord who lived in the state of Cao Wei during the Three Kingdoms period of China. He rebelled against Wei in 237 and declared himself "King of Yan" (燕王). In 238, the Cao Wei general Sima Yi led forces to Liaodong and successfully conquered Yan.
Cao Rui, courtesy name Yuanzhong, was the second emperor of the state of Cao Wei during the Three Kingdoms period. His parentage is in dispute: his mother, Lady Zhen, was Yuan Xi's wife, but she later remarried Cao Pi, the first ruler of Wei. Based on conflicting accounts of his age, Pei Songzhi calculated that, in order to be Cao Pi's son, Cao Rui could not have been 36 when he died as recorded, so the recorded age was in error; late-Qing scholars Lu Bi (卢弼) and Mao Guangsheng (冒广生) argued instead that Cao Rui was Yuan Xi's son.
The Four Commanderies of Han were Chinese commanderies located in the north of the Korean Peninsula and part of the Liaodong Peninsula from around the end of the second century BC through the early 4th AD, for the longest lasting. The commanderies were set up to control the populace in the former Gojoseon area as far south as the Han River, with a core area at Lelang near present-day Pyongyang by Emperor Wu of the Han dynasty in early 2nd century BC after his conquest of Wiman Joseon. As such, these commanderies are seen as Chinese colonies by some scholars. Though disputed by North Korean scholars, Western sources generally describe the Lelang Commandery as existing within the Korean peninsula, and extend the rule of the four commanderies as far south as the Han River. However, South Korean scholars assumed its administrative areas to Pyongan and Hwanghae provinces.
The Goguryeo–Wei War was a series of invasions of Goguryeo from 244 to 245 launched by Cao Wei.
Cáo is the pinyin romanization of the Chinese surname 曹 (Cáo). It is listed 26th in the Song-era Hundred Family Surnames poem. Cao is romanized as "Tsao" in Wade-Giles (Ts'ao), which is widely adopted in Taiwan, although the apostrophe is often omitted in practice. It is romanized "Cho", "Tso", and "Chaw" in Cantonese; "Chou", "Chô", and "Chow" in Hokkien; and "Chau", "Chow" in Teochew. It is romanized "Zau" or "Dzau" in Shanghainese.
Liang Mao, courtesy name Bofang, was a scholar and official serving under the warlord Cao Cao in the late Eastern Han dynasty of China.
Yan was a Chinese kingdom that existed from July 237 to September 238 CE in the Liaodong Peninsula during the Three Kingdoms period. Its predecessor was an independent regime ruled by Gongsun Du and his son Gongsun Kang from 190 to 237. Though it only claimed independence in 237, historians such as Wang Zhongshu and Hou Tao consider it to be a de facto independent regime from when Gongsun Du established his rule in Liaodong in 190. Although it existed during the Three Kingdoms period, it is not counted as one of the eponymous three kingdoms: Cao Wei, Shu Han, and Eastern Wu. Nevertheless, writers such as Kang Youwei consider it to be a "fourth country".
