books have been written trying to explain why the nazis didn't like the jews.
easy answer? they were a scapegoat for germany's problems. the jews have been blamed for the world's problems since forever and nazis were simply playing off of a very old fear.
jewish people have always been discriminated against so they were an easy target for hitler to pick on
for example the crusades, for the holy land
i have no idea. i am not %100 sure, but the main reasons most places would push is for more land. when their colonies were starting to get larger, they needed more land, and spain had the most people in their colony and the best weapons than any other place at that time making them superior to other colonies.
i would say a.. ending child labor.
lewis hine was an activist for the national child labor committee. mother jones was a school teacher as well as a female activist. even though she was most famous for being the founder of the industrial workers of the world, i think she would be united with lewis hine with ending child labor.
