The answer is:

  • the printing press
  • the Crusades

The Industrial Revolution began in Great Britain in the 1870's, and involved the change from hand labor to machine production. It was influenced by Johann Gutenberg's invention of a printing system adapted from existing techniques, as well as by the Europe's interest in dismissing its isolation, which encouraged trade, travel and the coalescence of new concepts.
