The stirrup and the dispute over its social consequences
The stirrup, two loops of leather, rope, or iron suspended from the sides of a saddle, allows a rider to press against his feet: this increases stability and, above all, the force of the lance-strike. In Europe the stirrup is first documented in the military treatise Strategikon of the Byzantine Emperor Maurice, 582-602; in the East (China, Japan) it is a couple of centuries older. On one account it was brought to Europe by nomadic horsemen of the steppes.
A long-standing dispute surrounds its social consequence in Western Europe. Lynn White Jr. in Medieval Technology and Social Change (1962) built the famous chain: the stirrup made possible mounted shock combat with the lance couched under the arm; such cavalry requires expensive horses and armour; to maintain it one needs a conditional land rent (the fief); therefore the stirrup triggered feudalism in the Carolingian age. The thesis entered the textbooks.
Medievalists have refuted it consistently. Bernard Bachrach (Charles Martel, Mounted Shock Combat, the Stirrup, and Feudalism, 1970) showed that heavy shock cavalry appeared in Western Europe later than the wide spread of the stirrup and that the Carolingian army fought largely on foot. Peter Sawyer and Rodney Hilton in Past & Present of 1963 put it more briefly: 'the introduction of the stirrup is not in itself an adequate explanation for any changes that may have occurred'. Stephen Morillo in the 1990s tied the appearance of knightly cavalry to political fragmentation rather than to technology. Today White's thesis in its original form is rejected; the stirrup itself remains.
The card follows the pattern of Bacon and Hime (see decision 047): a node about a technology that has a documented date, with the dispute over its social consequences laid out in the text.
Why this date
disputed. The date of the documented appearance of the stirrup in Europe, around 600 (Emperor Maurice's Strategikon, 582-602), is taken from the 1911 Britannica. In the East the stirrup is older: pre-7th-century specimens are known archaeologically in Japan and are mentioned in early Chinese literature. The social consequence is separately disputed: Lynn White Jr. in Medieval Technology and Social Change (1962) built the chain stirrup, mounted shock combat, feudalism; the medievalists Bachrach (1970) and Morillo (1990s) rejected it. The date of the card is tied to the technology, not to the dispute.
Two sources: 1911 EB 'Stirrup' supports the technology itself with the date (Maurice, 582-602); Hemming via Kwantlen Polytechnic (open textbook, CC BY 4.0) supports the refutation of White's thesis. By rule 046 two sources are allowed because the card carries a separate disputed claim. WebFetch on kpu.pressbooks.pub returns HTTP 403; the editor confirmed the quote by hand and check-quotes will log it as by=editor-visual (decision 042). A direct quote from White's Medieval Technology and Social Change (1962) has not been found in open access through WebFetch (the archived djvu is served only via CDN behind 401); on transfer to core a third source can be added.

Between them, these two articles presented extensive primary-source evidence that largely demolished the support that White had put forward for his theory.
