Through which treaty was the East African Development Bank originally established to promote regional economic development?

Introduction / Context:
Regional development banks are crucial instruments for financing infrastructure, industry, and social projects in specific geographic areas. The East African Development Bank is one such institution that serves countries in East Africa. This question asks about the treaty through which the bank was originally established, a detail that connects banking, regional integration, and treaty based cooperation in Africa.

Given Data / Assumptions:

• The organisation referenced is the East African Development Bank.
• Several similar sounding treaties are given as options, each linked to cooperation or unity in Africa.
• We must identify the exact treaty that created the bank in its original form.
• The year 1967, associated with East African regional cooperation, is particularly relevant.

Concept / Approach:
The East African Development Bank was established under the Treaty for East African Co operation of 1967, which aimed to promote economic integration among East African states. This treaty provided a legal framework for shared institutions, including the development bank. Other treaties listed in the options are either generic or do not correspond to the bank creation. Therefore, a careful reading and recall of the full treaty title and year is essential.

Step-by-Step Solution:
Step 1: Identify that the question is about the origin of the East African Development Bank.Step 2: Recall that the bank was created as part of institutional arrangements under the Treaty for East African Co operation signed in 1967.Step 3: Compare the answer options and note which one exactly matches this treaty name and year.Step 4: Recognise that Option A explicitly states Treaty for East African Co operation, 1967.Step 5: Select Option A as the correct answer and reject other treaties that either have different names or years.

Verification / Alternative check:
One can verify the answer by recalling that the East African Community and related institutions have roots in agreements from the mid to late 1960s focused on cooperation among Kenya, Tanzania, and Uganda. Historical references to the East African Development Bank almost always mention the Treaty for East African Co operation of 1967 as its founding instrument. The other listed treaties do not appear in standard descriptions of the bank history.

Why Other Options Are Wrong:
Option B, Treaty for African Co operation, 1965, is wrong because it is a generic phrase and not the specific legal instrument that created the bank.Option C, Treaty for African Unity, 1968, is wrong because it does not correspond to the name or year associated with the East African Development Bank formation.Option D, None of these, is wrong because Option A already provides the correct treaty.

Common Pitfalls:
Students may be confused by similar sounding treaty names and by the temptation to choose None of these when they are unsure. Another pitfall is to mix up the East African Development Bank with the African Development Bank, which has a different founding treaty and membership. To avoid confusion, learners should note that the East African Development Bank is more regional and is linked specifically to the Treaty for East African Co operation, 1967.

Final Answer:
Treaty for East African Co operation, 1967
