Cause : The abolition of Corn Laws led to the import of cheap agricultural products in England.Unable to compete with imports, many left agricultural activities and flocked to the cities. This led to large scale migration of people to cities and overseas. This indirectly led to global agriculture and rapid urbanisation, a prerequisite of industrial growth.Countries like Eastern Europe, Russia, America and Australia increased their food productivity to meet the British needs and in the process, slowly became industrialised to different degrees. Effects : Nearly 50 million people migrated from Europe to America and Australia in the nineteenth century. Another estimate was the migration of about 150 millions of the world population, mostly from Europe, who crossed the oceans for a better life. By the end of the nineteenth century, a global agricultural economy replaced the earlier self-sufficient economy.Industries and factories helped in a better flow of capital and technologies. Colonies were firmly established and they provided cheap raw materials and labour, who manned most of the railways in Southern Europe, Asia, Africa and the Caribbean.
