During the colonial period of Arabs living in Kenya much economic, socio-cultural and political influences occurred. Islam was introduced to the region; commercial trade between the regions increased enormously (both export and import); the modest living of the Arabs developed a sensibility to trade in the early colonialist period forming more capital for investment; there was a relative amount of hostility due to the apolitical nature of the Yemeni Arabs in becoming involved with the Kenyan Politics; the intermarriage of Arabs and Kenyans resulted in the formation of the Swahili people forming the Bantu Language which resulted from heavy Arab influence.
1. Economy (to make cheap cash and get labor)
2.political (more land=more power)
And lastly 3. Religion (europeans wanted to spread christianity)
The mood of the poem "The Hollow Men" can best be described as "melancholy" although it should be noted that this is of course somewhat subjective to the reader.
Galileo figured out that the earth revolved around the sun (or he built on that theory). The Catholic church however, taught that the earth was the center of the universe. IF they were proved wrong (and they were) people would question their other doctrines and teachings, and so they wanted Galileo to keep quiet about his discoveries.
hope this helps
