Gold rush became the cause of the industrialization in USA.justify
In the 1840s, traces of gold were found in the USA, in California. This led to the 'Gold Rush' at the time when thousands of eager Europeans hurried to America in the hope of making more fortune. This led to building of railway lines across the continent. Industries developed to manufacture railway equipment. This too led to increase in production of lumber and the creation of new flour mills. The need for clothing increased dramatically, and the leather industry experienced significant growth. Wholesale and retail developed at this time and were instrumental in helping meet the growing demands of consumers. So this gold rush became the major cause of industrialisation in USA.
