Which invention would have been the most important for spreading european infulence in africa

The new method of getting quinine from cinchona tree bark was most important for spreading European influence. Without it, the Europeans wouldn’t have explored/colonized much more of Africa than the coast because they were so susceptible to malaria. On the other hand, the next most important technological advancements to spreading European influence in Africa are the Maxim gun and Repeating rifle. These gave more power to the Europeans because they could force the African people to do things by threatening them with getting shot. However, the guns would have done nothing if the Europeans were going to catch malaria and die.

the neutrality acts were passed by the united states congress in the 1930s, in response to the growing turmoil in europe and asia that eventually led to world war ii. they were spurred by the growth in isolationism and non-interventionism in the us following its costly involvement in world war i, and sought to ensure that the us would not become entangled again in foreign conflicts.

the legacy of the neutrality acts is widely regarded as having been generally negative: they made no distinction between aggressor and victim, treating both equally as "belligerents"; and they limited the us government's ability to aid britain and france against nazi germany. the acts were largely repealed in 1941, in the face of german submarine attacks on u.s. vessels and the japanese attack on pearl harbor.

there are a number of different ideologies that come into conflict with regard to immigrants and immigration to the us.
