The primary reason the muslim population in spain grew between the time of muhammad and the time the alhambra(c 900) was built was that

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof

i think the answer is: cuba wanted to be independent from spain, and the u.s. wanted to end spanish rule in the west.
