A good watchword for the industrial revolution would be invention.
Explanation:
Industrial revolution was marked by societal change on a level that was never seen before as city spaces came into existence over a matter of years and complete demographics of countries changed from rural heavy to urban heavy.
This was largely due to technological innovation which meant that more production and assembly lines were possible and less people needed to work in farms.
This was not possible without various inventions of the machine and developments in electricity.
