Which of these was the main reason for berlin conference

The Berlin Conference of 1884–85, also known as the Congo Conference (German: Kongokonferenz) or West Africa Conference (Westafrika-Konferenz),[1] regulated European colonization and trade in Africa during the New Imperialism period and coincided with Germany's sudden emergence as an imperial power. The conference was organized by Otto von Bismarck, first Chancellor of Germany; its outcome, the General Act of the Berlin Conference, can be seen as the formalisation of the Scramble for Africa, although some scholars of history warn against an overemphasis of its role in the colonial partitioning of Africa, drawing attention to bilateral agreements concluded before and after the conference.[2][3] The conference ushered in a period of heightened colonial activity by European powers, which eliminated or overrode most existing forms of African autonomy and self-governance.[4]

Explanation:

  a) written constitution. also known as magna carta and a necessity of the democracies that form federations to regulate the principles by which the government will be governed, because if they had to act without a body of specific laws would produce confrontations.

b) territorial division. federalism is constituted by the division of powers on the geographical basis of each territory.

c) decentralization. in a federal system there is both a central government and units of government lower than the central one, each making decisions regarding the provision of certain public services in their respective geographical jurisdictions.

d) supreme court of justice. to counteract the rigidity of the written constitution, judicial action is required to interpret said constitution and necessary changes can be made.
