the american revolution was between the patriots and the british forces. the patriots believed that they needed independence from great britain, due to "lack of representation" and taxes. this tension resulted in the american revolution where both fought, but ultimately the patriots won. the french revolution was an upsurge/revolt between the monarchy (king louis xvi of france) and the bourgeoisie class (common people) demanding better pay and rights. this ultimately became an overthrow of the government, where king louis xvi of france and his spouse marie antoinette were executed for treason. the mexican revolution was caused by a disagreement on the morality of the dictatorship of president porfirio díaz, who remained in office for 31 years. (! d: )   in effect, the old and radical government was changed by the people to meet the economic needs of the people (yes diaz surrendered xd) all 3 revolutions were in response to another political power that controlled the freedom and liberty of the minority population. the british controlled the patriots. king louis xvi controlled the people of france, and dictator diaz controlled the poor civilians of mexico.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
