Answer:
The city of Iquitos formed along the Amazon in 1910 in response to the rubber boom.
Step-by-step explanation:
Iquitos is the largest metropolis in the Peruvian Amazon, and is the seventh most populous city in Peru with a population of 479,866 inhabitants.
It has been one of the major cities, along with Manaus and Belem in Brazil, of the huge Rubber Rush (1880-1914). The rubber rush experienced its peak between 1879 and 1912, experiencing, sometime later, a revival between the years 1942 and 1945. The discovery of vulcanization and the pneumatic chamber in the 1850s led to a extractive rubber fever.
