Zviumbwa zvevhu zvaishandiswa muChina yekare kubva panguva yeShang Dynasty (c. 1600 kusvika 1046 BC).Houmuwu ding yakakurumbira (c. 1300 BC) yakagadzirwa nevhu rekuumba.

Mambo weAsiria Seniheribhi (704–681 BC) akakanda mabhuronzi makuru anosvika matani makumi matatu, uye anoti ndiye akatanga kushandisa zviumbwa zvevhu kwete nzira ye“kurasika-namo”.

Nzira yekuumbwa kwejecha yakanyorwa naVannoccio Biringuccio mubhuku rake rakadhindwa kunosvika 1540.

Muna 1924, kambani yemotokari yeFord yakagadzira rekodhi nekugadzira mota dzinosvika miriyoni imwe, mukuita ichipedza chikamu chimwe muzvitatu chezvese kugadzirwa kwemuUS.Kuwedzera kuri kudiwa kwekukandwa muindasitiri yekuvaka mota uye muchina munguva uye mushure meHondo Yenyika I uye Hondo Yenyika II, yakasimudzira zvigadzirwa zvitsva mumakanika uye gare gare otomatiki yejecha rekukanda process tekinoroji.
