The Industrial Revolution began in the 18th century in England and spread across the world. It transformed economies from agrarian and handicraft to machine manufacturing and industry. Notable inventions like improved transportation and communication led to changes. Managers were needed to coordinate large factories. Early thinkers like Robert Owen, Andrew Ure, and J.N. Tata emphasized treating workers humanely by banning child labor, providing benefits, and improving safety. However, their ideas were not widely accepted at the time and management of people was not fully recognized as important.
