The history of Mengzi can be traced back toWestern Han dynasty whenBengu County (贲古县) was founded (109 B.C.), which was currently the area ofXin'ansuo, Mengzi.
Not until in 1276 (Yuan dynasty), Mengzi county was formerly founded, which can be regarded as the prototype of the modern Mengzi City.
In 1886, following the war between France and the Qing China, a series of treaties designated Mengzi as a trade port in Yunnan province for the import and export of goods viaTonkin, currently the Northern Vietnam. Under the terms of these treaties, foreigners were allowed to reside and trade in Mengzi. Accordingly, the foreign-operated Imperial Maritime Customs Service established its office just outside the eastern city gate of Mengzi in 1899.[15]
Communications were inconvenient: goods fromHanoi orHaiphong were shipped toHekou on the Vietnamese border by junk, transferred by small craft toManhao, and then taken 60 km (37 mi) by pack animal to Mengzi. Despite these difficulties, Mengzi was an important port of entry into bothYunnan and westernGuizhou provinces, and in 1889 it was opened to foreign trade as a treaty port. Throughout the late 19th and early 20th century, Mengzi was a major trading center for commerce between the interior of Yunnan and the Tonkin. Most of this foreign trade was in tin and opium. Its main exports were tin andopium, and the main imports were mostly textiles (primarilycotton) andtobacco.
As a trading center, the city gradually began to lose its importance beginning from the early 20th century. The importance of Mengzi was ended by the construction of theFrench railway fromHaiphong to Kunming (the Yunnan provincial capital) in 1906–10. This railway bypassed Mengzi, but in 1915 abranch line was built via the town to theGejiu tin mines. Apart from a brief respite during the early days ofWorld War II, the town of Mengzi has, nevertheless, steadily declined in importance ever since.
Gejiu became a county in 1913, and a city in 1951. With the improvement of communications and transportation between cities ofGejiu andKaiyuan and the other counties nearby, plus the development of trade between southwestern China and the countries of Southeast Asia, Mengzi's ties have increasingly strengthened with Gejiu and Kaiyuan. The whole area has become a border economic centre. In addition to tin, the county's natural resources include coal, manganese, lead, zinc, and antimony.
When the Japanese invadedBeijing andTianjin in the late 1930s, university professors, students, and administrators there were forced to leave and travel south toChangsha. Later as the Japanese pushed into Changsha, the academics made their own long march westward to Yunnan Province. There they established theSouthwest Associated Universities, also known as Lianda (Chinese:联大). The School of Arts and Law was located in Mengzi, but moved to the provincial capital ofKunming about half a year later.
In 2003,the prefectural government of Honghe [zh] moved from nearby Gejiu to Mengzi. New wealthy suburbs and large government offices have sprung up as a result, but much of the poverty remains, creating a largewealth gap within the city.
In 2012, 11-14 thousand year old early human bones fromMaludong near Mengzi City (some of them already in museum collections) were reported. These are provisionally known as theRed Deer Cave people.[16]

Mengzi used to be a medium-sized county town before the prefectural government relocated there from theCity of Gejiu in 2003.[19] Since then, the city has witnessed a rapid urban and economic expansion with significant infrastructure projects.[19][20] In 2010, Mengzi was elevated to acity administratively.
Real estate industry is pivotal sector of the city's economy. Recent policy developments have promoted economic growth, leading to substantial changes in the local industry structure and employment landscape.[21]

Honghe Mengzi Airport in Mengzi is under construction.[23]
