Question: was the colonization of cape verde peaceful or not? 

Answer: The Cape Verde islands experienced the longest period of European colonization of any African nation. The Portuguese remained in direct control of this island archipelago from 1460 to 1975. In their struggle for independence from Portugal, beginning in the 1950s, the people of Cape Verde linked their fortunes to that of Guinea Bissau on the West African mainland under a unified movement, the PAIGC (African Party for the Independence of Guinea-Bissau and Cape Verde), formed in 1956.The armed struggle against the Portuguese lasted from 1963 until 1974 when a negotiated peace settlement was arranged. While achieving independence for themselves, the Portuguese African resistance movements, including those of Angola and Mozambique, had succeeded in bringing down the fascist Portuguese government in Lisbon. Elections were held in June 1975, and the Republic of Cape Verde was declared formally independent from Portugal on 5 July.\n\nAlso check out http://www.britannica.com/eb/article-129476/Cape-Verde\n\nHope some of this helps =)
