Pope Gregory VII (1020-1085) was the pope of the Catholic Church from 1073 to 1085. He established the Gregorian Reforms to the Catholic Church that included the new canon law that governed the election of the pope via the College of Cardinals and the assurance of the moral integrity of the members of the clergy.

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.
