how did the spoils system affect president james garfield and his successor chester a arthur ?

he tried to limit them

President Garfield was killed from a government employee who disagree with the Spoils system because it does not consider the limit of the people. When Arthur took over, he threw away the Spoils system and signed the Pendleton Act.

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.
