Courtesy of the Spaghetti wikipedia page:
https://en.wikipedia.org/wiki/Spaghetti"The popularity of spaghetti spread throughout Italy after the establishment of spaghetti factories in the 19th century"
Pasta was invented in China thousands of years ago anyway, but even after invading Italy in WWII no Brit remembered Spaghetti was a thing over there only a few years later in 1957.
Confirmed for retards
