Industrial Revolution and Immigration
Industrial revolution in the United States is tightly related to the immigration into America. Although immigration into the country has been (and probably will always be) an inseparable part of American history, industrial revolution has had its effect on the quantities of migrants leaving Europe. 
There are many factors that connect migration to industrial revolution. Industrial revolution (dated late 18th – early 19th century) happened not only in America, but in other countries as well. It first appeared in Great Britain, and spread all over the world. America also had its part, which was accompanied with technological, economic, social, and even cultural changes in society. The major change at those times was the substitution on manual labor by machinery. However, production of machinery required huge labor force, and led to the creation of factories. These factories, in turn, required many workers to keep operational. Workers were needed not only in the factories, but in additional complementary sectors like transportation (both water and land), supplies delivery, research and development, etc. Thus, there has been a demand for workers, which is one of the reasons of immigration. 
Interestingly, women and children worked in mills and factories together with men, mainly because of the financial reasons, and because there were not enough workers in the factories. Most notably, less fortunate women spent days in horrible working conditions doing man’s job. After work, they usually had to go home and conduct household needs such as washing, cleaning, etc. In addition, society at those times was such that expected families to have many children. Thus, women typically bore 7 and more children. It is important to note that they did not have any pregnancy or medical leave, and thus had to work the next day after delivery.
The second reason that links industrial revolution to immigration into the United States is that in Europe there has been a rapid increase of population; with the development of medicine and technologies, death rates decreased. Moreover, large portion of population had no national identity, like for example Jews or Gypsies, and sought freedom in the West. Furthermore, wars in Europe have made many refugees to flee to the West. 
Ultimately, industrial revolution had a strong influence on the lives of American citizens, the immigrants from Europe. It had tremendously impacted the life of women, forcing them to work very hard in factories in horrible working conditions, do household chores, and have many children.
