Eli Whitney invented the cotton gin, during the Industrial Revolution, which would change the American economy dramatically. Before this time, picking seeds out of cotton was a long, tedious process. Along with this, the profits generated from cotton were not worth the work that it took. However, this changed when Whitney invented a device that would separate the seeds from the cotton at a rapid pace.

This invention helped spark the popularity of cotton, as it could now generate huge profits thanks to the reduced amount of time it took to remove the seeds from the cotton.

angel island immigration station was an immigration station located in san francisco bay which worked from 1910 to 1940. the majority of immigrants that got there were from the asian hemisphere, specifically from china, japan, russia, and south asia, being china the country from where more people arrived.

the number of foreigners arriving at it took the attention of americans who feared the new arrivals would take their jobs. the work opportunities were not abundant due to the economic comedown of 1870 and the asians, as newcomers, were willing to work for cheaper wages. soon they started to be seen as a threat, which led to an increased discrimination against the chinese - the biggest ethnicity arrived at this station until 1915 when japanese immigrants outnumbered them - being considered as unsuitable americans hence their looks and social situation.

at the station, the immigrant's detention may vary depending on how long the interrogation process took: it could be weeks, months, or even years.

finally, in 1940 an explosion destroyed administration building located on the island, so the united states government decided to stop the process.
