漢 (simplified Chinese: 汉; pronounced hàn in Mandarin) is a Chinese character with one of the deepest cultural footprints in East Asia. It first appears in bronze inscriptions from roughly 3,000 years ago as the name of a river. From there, it became the name of one of China's most influential dynasties, and through that dynasty, it became the standard term for the Chinese people themselves.

The character's reach extends across the region. The names that three different countries use for "Chinese characters" — hànzì in China, kanji in Japan, and hanja in Korea — are all written with 漢 followed by 字 ("character"). The same character also gives Wuhan its name, appears in countless personal and place names across East Asia, and has even acquired meanings in Japanese that have nothing to do with China at all.

The meanings of 漢 trace a path from geography to history to identity, with each new sense building on the previous one.

The original meaning of 漢 is the Han River, a major waterway in central China. It rises in the mountains of Shaanxi Province, flows southeast through Hubei Province, and joins the Yangtze at the city of Wuhan — whose name literally means "Wu plus Han," after the river. The Han is the longest tributary of the Yangtze and has been an important trade and travel route for thousands of years.

The river's importance is built into the structure of the character itself. The left side of 漢 is 氵, the "water radical," a graphical element that signals the character relates to water in some way. Roughly 80–90% of Chinese characters are constructed this way, with one part hinting at meaning and another at sound.

In classical poetry, 漢 was extended to mean the Milky Way, often called the "heavenly river" (天漢, tiānhàn). Ancient Chinese poets saw the band of stars stretching across the night sky and described it as a celestial counterpart to the Han flowing across the earth.

In 206 BCE, a former peasant turned rebel commander named Liu Bang founded the Han dynasty. Before taking the throne, he had been granted a fiefdom called Hanzhong (漢中) — "the middle reaches of the Han" — situated along the upper Han River. When he became emperor, he kept that geographic name for his new dynasty.

The Han dynasty lasted, with one brief interruption, from 206 BCE to 220 CE, ruling China for more than four centuries. It is widely regarded as a golden age. Paper was invented during the Han, the Silk Road opened to connect China with Central Asia and the Mediterranean, Confucianism was established as the state philosophy, and a professional civil service began to take shape. The dynasty's prestige was so durable that, more than a thousand years later, several smaller kingdoms still chose to call themselves "Han" to claim its legacy.

The most far-reaching use of 漢 emerged after the dynasty fell. During the Northern and Southern Dynasties period (roughly the 4th to 6th centuries CE), as China fragmented and various non-Chinese peoples ruled parts of the country, the ethnic Chinese population began identifying themselves as "Han people" — invoking the dynasty as a symbol of cultural unity and prestige.

The label stuck. Today, the Han Chinese are the largest ethnic group in China, comprising roughly 92% of the country's population, and the largest ethnic group in the world by a wide margin. The term distinguishes them from China's 55 officially recognized ethnic minorities, including Tibetans, Uyghurs, Mongols, and Manchus.

Before this usage took hold, the Chinese had referred to themselves and their land using older terms like Huaxia (華夏) and Zhuhua (諸華). These terms still exist but are now mostly literary or formal.

In addition to the major senses above, 漢 carries some smaller, related meanings:

• A man — particularly a tough or admirable one. This developed in Chinese from the contrast between "civilized" Han people and outsiders, and it survives in expressions like hǎohàn (好漢, "true man, hero") and nánzǐhàn (男子漢, "real man").
• A husband — an older usage, now mostly literary.
• A surname — though relatively uncommon.

漢 is a phono-semantic compound, the most common type of Chinese character. It combines a meaning element with a sound element:

• Left side: 氵, the water radical (a compressed form of 水, "water"), indicating the character's connection to a body of water
• Right side: 𦰩, a phonetic component that originally suggested the character's pronunciation

The right side has a complicated history. In the earliest forms found on Western Zhou bronzes around the 11th century BCE, it depicted a bound human figure, possibly crying out. Some scholars connect this to ancient sacrificial practices in which prisoners were burned to pray for rain — which would explain the water radical. Over the centuries, this element gradually changed shape and lost its original pictorial meaning, settling into the form we see today.

In the 1950s, the People's Republic of China introduced a simplified character set to improve literacy. The simplified form of 漢 is 汉, in which the elaborate 𦰩 component is replaced with the much simpler 又. The traditional form has 14 strokes; the simplified form has only 5.

• Traditional (Taiwan, Hong Kong, Macau): 漢 — 14 strokes
• Simplified (mainland China, Singapore, Malaysia): 汉 — 5 strokes

Japan and Korea both retained the traditional form. Japan's standard form, called shinjitai ("new character form"), is essentially identical to the Chinese traditional version, with a one-stroke difference in the top of the right-side component that most readers would not notice. Because of Han unification in the Unicode standard, the Chinese traditional and Japanese shinjitai forms share a single code point (U+6F22), and which one you see depends on the font your device is using.

Because 漢 was borrowed into Japanese, Korean, and Vietnamese over the course of more than a thousand years, each language has its own pronunciation. The Japanese case is especially complex, with both Chinese-derived readings (on'yomi) and native Japanese readings (kun'yomi).

漢 is one of the most productive characters in the East Asian writing tradition, appearing in hundreds of compounds across multiple languages.

The most globally recognized use of 漢 is in the names that three East Asian languages give to Chinese characters themselves:

In all three cases, 漢 carries the meaning "Han / Chinese" and 字 means "character" or "written symbol." Vietnam historically used a similar term, Hán tự (漢字), though Vietnamese is now written almost exclusively in the Latin alphabet.

漢 is one of the most frequent characters in everyday Chinese. A small selection of common compounds:

• 漢語 / 汉语 (hànyǔ) — the Chinese language
• 漢族 / 汉族 (hànzú) — the Han ethnic group
• 漢服 / 汉服 (hànfú) — traditional Han Chinese clothing, popularized again in recent years through a cultural revival movement
• 漢堡 / 汉堡 (hànbǎo) — hamburger; also the city of Hamburg, Germany. Both are pure phonetic borrowings — the character's meaning is irrelevant here.
• 武漢 / 武汉 (Wǔhàn) — the megacity of Wuhan in Hubei Province
• 男子漢 / 男子汉 (nánzǐhàn) — "a real man," conveying toughness and integrity

Japanese has expanded the use of 漢 in directions Chinese never took. Beyond the standard kan reading used in compound words borrowed from Chinese — such as 漢方 (kanpō, traditional Chinese medicine), 漢詩 (kanshi, Chinese-style poetry), and 漢文 (kanbun, Classical Chinese literature) — Japanese uses 漢 to describe particular kinds of men:

• 巨漢 (kyokan) — a giant of a man
• 暴漢 (bōkan) — a thug or hoodlum
• 大食漢 (daishokukan) — a heavy eater; a glutton
• 熱血漢 (nekketsukan) — a passionate, hot-blooded person
• 門外漢 (mongaikan) — a layman; an outsider to a particular field

There is also a slangy, dramatic use of 漢 read as otoko — the same word normally written 男, "man." Writing otoko as 漢 instead of 男 carries connotations of romantic toughness, the way an English writer might capitalize "Man" for emphasis. This usage shows up most often in manga, video games, and martial-arts contexts.

The reading kara (から) has a different history. It originally referred to the Gaya confederacy, a coalition of small states in southern Korea that existed from the 1st to 6th centuries CE. The meaning gradually expanded — first to the Korean peninsula in general, then to China, and eventually to foreign lands as a whole. This is why some Japanese words for things imported from abroad use 漢 with the kara reading, even when those things are not specifically Chinese.

In Korean, 漢 is read as han (한) and appears in many words borrowed from Chinese, including 한자 (漢字, hanja, Chinese characters), 한문 (漢文, hanmun, Classical Chinese), and 한족 (漢族, hanjok, the Han ethnic group).

It also appears in a name familiar to anyone who has visited Seoul: the Han River (한강, Hangang), which runs through the South Korean capital. Despite sharing the character 漢 with the Chinese Han River, the two are not actually related. The Korean river's name comes from a native Korean root meaning "great" or "big," and 漢 was simply borrowed to write the sound — a common pattern in pre-modern Korean, when most writing was done with Chinese characters.

The historical Chinese name for Seoul itself, Hanseong (漢城, "Han City"), used this same character. The name was officially retired in 2005 in favor of the new Chinese rendering Shǒu'ěr (首爾), which is a phonetic approximation of "Seoul."
