Timeline of historic inventions

The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and the people who created the inventions.

Note: Dates for inventions are often controversial. Inventions are often invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.

The dates listed here refer to the earliest known evidence of an invention. Dates are often approximate and may change as more research is completed. Older examples of any given technology may arise in the future. The locations listed are for the site where the earliest solid evidence has been found, but in most cases there is little certainty how close that may be to where the invention took place.

Note the shift from Ma and ka to BC and AD – 8000 BC is approximately the same as 10 ka.
