what the h*ck

The fucking chair
guess: 200AD in Rome

cannons
guess: perhaps around the middle ages, late 11th century, somewhere in china
truth not that far, 12th century, china, they were first used as depicted in the Huolongjing, the Fire Dragon Manual. but it was upgraded later to a much diffrent design, instead of a bamboo spear, a handheld bore of iron with a steel ball inside it which is technically the first rifle, to then a much larger cannon on wheels by late 13th century..first used against the mongols, then in their invasion of japan, and then on a much bigger scale in the red turban rebellion

Invention: Rope
Guess: 4000BCE
Answer: t is likely that the earliest "ropes" were naturally occurring lengths of plant fibre, such as vines, followed soon by the first attempts at twisting and braiding these strands together to form the first proper ropes in the modern sense of the word. The earliest evidence of suspected rope is a very small fragment of three-ply cord from a Neanderthal site dated 50,000 years ago.

Invention: cigarettes (as opposed to cigars, pipes, smoking tubes)
Guess: 1750
Answer: 1830s

Pottery is something seen so early in so many regions that it's used as a dating tool, but what about porcelain (i.e. china)? It needs a very specific mixture of silicates and was a closely guarded secret to other nations until the 17th century, so i'd say 800 CE or so.
It's from about 600 CE, 1600-1000 BCE or somewhere in between, depending on how far you stretch the definition.

speaking of
Invention: Silk
Guess: ~500CE China
Answer: Wikipedia is ass regarding this. The article for silk says 5000BCE but cites a Chinese legendary figure who is supposed to have lived in the 28th century BCE… that don't make no damn sense. The whole thing with silk is boiling the cocoon of the silkworm while the pupa is still inside. But I can't find any information on when this process was actually begun. I doubt both 5000 BCE and 28th century BCE are realistic answers.

>>691114 (You)
ok the chinese wiki article when translated is way better than the english article and discusses the archaeological evidence for silk production being very old:

However, there is still controversy about when silk was invented. In 1998, archaeologists discovered silk fragments dating back about 5,500 years during an archaeological excavation at the Qingtai site in Xingyang, Henan . Another theory is that people found textile tools at the Hemudu site , which can be inferred that the use of silk was at least no later than the Liangzhu culture [ 1 ] . However, the most influential theory in the world is the silk fabrics discovered by Chinese scientists in 1958, dating from 3700 to 3100 BC ( Dawenkou culture period).

Gold medals in sports competitions

My guess: Antiquity.
Wikipedia says:
Since the eighteenth century, gold medals have been awarded in the arts (…) The custom of awarding the sequence of gold, silver, and bronze medals for the first three highest achievers dates from at least the 19th century, with the National Association of Amateur Athletes in the United States awarding such medals as early as 1884.

Guess: France, 1825

Don't rely on wikipedia for origins of things, they lie about when terms were coined all the time
for example the stub on anarchist transhumanism had lead to AI lying that the term was "invented" by market economist William Gillis who was practically a teenager in the early 2000s and has no evidence of using it first, whereas a credible page archive pointing to its usage prior to William Gillis even appearing on the internet thatdates back to at least 2004 pointing to person by the name of Robin Green coining it 1999 was removed by glowpedia editors on the premise "no original research allowed"
http://www.fact-index.com/t/tr/transhumanist_anarchism.html
this kind of faggotry from glowpedia agents is seen everywhere.
