The absence of an armed force like the [[United Nations]] [[United Nations peacekeeping|peacekeepers]] left the organization with no means to enforce its decisions. It was also unwilling to become involved in the internal affairs of member nations, prompting some critics to claim the OAU as ineffective in taking decisive action. Recognizing this, in September 1999 the OAU issued the [[Sirte Declaration]], calling for a new body to take its place. On 9 July 2002, the OAU's [[Chairperson of the Organisation of African Unity|Chairman]], [[President of South Africa|South African President]] [[Thabo Mbeki]], formally dissolved the OAU and replaced it with the [[African Union]] (AU), its immediate successor, which upholds many of the founding principles of the OAU.<ref>{{Cite web|last=Beverton|first=Alys|date=2009-05-10|title=Organization of African Unity (1963–2002) |url=https://www.blackpast.org/global-african-history/organization-african-unity-1963-2002/|access-date=2021-05-27|language=en-US}}</ref>

:It is barely 75 years when the European Powers sat around the table in Germany each holding a dagger to carve up Africa for its own benefit.… Your success will inspire and speed up the freedom and total independence of the African continent and eradicate imperialism and colonialism from the continent and eventually neo-colonialism from the globe… Your failure, which no true African in Africa is praying for, will prolong our struggle with bitterness and disappointment. I, therefore, adjure that you ignore any suggestion outside Africa and holding that the present civilization, which some of the big powered are boasting of, sprang up from Africa, and realising that the entire world has something earthly to learn from Africa, you would endeavour your utmost to come to agreement, save Africa from the clutches of neo-colonialism and resurrect African dignity, manhood and national stability.

==Aims==
{{more citations needed section|date=May 2013}}
The OAU had the following primary aims:
[[File:Selassie_and_Nasser,_1963.jpg|thumb|Emperor of [[Ethiopia]] [[Haile Selassie]] with President of [[Egypt]] [[Gamal Abdel Nasser]] in [[Addis Ababa]] for the Organisation of African Unity summit, 1963]]
* To co-ordinate and intensify the co-operation of [[Africa]]n states in order to achieve a better life for the people of Africa.<ref name="dfa.gov.za"/>
* To defend the sovereignty, territorial integrity and independence of African states.
* The OAU was also dedicated to the eradication of all forms of [[colonialism]] and white minority rule as, when it was established, there were several states that had not yet won their independence or were white minority-ruled. [[South Africa]] and [[Angola]] were two such countries. The OAU proposed two ways of ridding the continent of colonialism and white minority rule. First, it would defend the interests of independent countries and help to pursue the independence those of still-colonised ones. Secondly, it would remain neutral in terms of world affairs, preventing its members from being controlled once more by outside powers.

A Liberation Committee was established to aid independence movements and look after the interests of already-independent states. The OAU also aimed to stay neutral in terms of global politics, which would prevent them from being controlled once more by outside forces – an especial danger with the Cold War.

{{AU History}}

The OAU had other aims, too:

* Ensure that all Africans enjoyed [[human rights]].
* Raise the [[living standards]] of all Africans.
* Settle arguments and disputes between members – not through fighting but rather peaceful and diplomatic negotiation.<ref>{{Cite journal|last=Elias|first=T. O.|date=1965|title=The Charter of the Organization of African Unity|journal=The American Journal of International Law|volume=59|issue=2|pages=243–267|doi=10.2307/2196967|issn=0002-9300|jstor=2196967|s2cid=146867168}}</ref>

Soon after achieving independence, a number of African states expressed a growing desire for more unity within the continent. Not everyone was agreed on how this unity could be achieved, however, and two opinionated groups emerged in this respect:

* [[Casablanca Group|The Casablanca bloc]], led by [[Kwame Nkrumah]] of [[Ghana]], wanted a [[federation]] of all African countries. Aside from Ghana, it comprised also [[Algeria]], [[Guinea]], [[Morocco]], [[Egypt]], [[Mali]] and [[Libya]]. Founded in 1961, its members were described as "progressive states".
* [[Monrovia Group|The Monrovian bloc]], led by [[Léopold Sédar Senghor|Senghor]] of [[Senegal]], felt that unity should be achieved gradually, through economic cooperation. It did not support the notion of a political federation. Its other members were [[Nigeria]], [[Liberia]], [[Ethiopia]], and most of the former French colonies.

Some of the initial discussions took place at [[Sanniquellie]], Liberia. The dispute was eventually resolved when [[Ethiopia]]n emperor [[Haile Selassie I]] invited the two groups to [[Addis Ababa]], where the OAU and its headquarters were subsequently established. The Charter of the Organisation was signed by 32 independent African states.

At the time of the OAU's disbanding, 53 out of the 54 African states were members; [[Morocco]] left on 12 November 1984 following the admission of the [[Sahrawi Arab Democratic Republic]] as the government of [[Western Sahara]] in 1982.<ref>{{Cite web|url=https://www.blackpast.org/global-african-history/organization-african-unity-1963-2002/|title = Organization of African Unity (1963–2002) |first=Alys|last=Beverton|website=blackpast.org|date = 10 May 2009}}</ref>

==Criticism and praise==
The organisation was widely derided as a bureaucratic "talking shop" with little power. It struggled to enforce its decisions, and its lack of armed force made intervention exceedingly difficult. [[Civil war]]s in Nigeria and Angola continued unabated for years, and the OAU could do nothing to stop them.

The policy of non-interference in the affairs of member states also limited the effectiveness of the OAU. Thus, when [[human rights]] were violated, as in [[Uganda]] under [[Idi Amin]] in the 1970s, the OAU was powerless to stop them.

The Organisation was praised by Ghanaian former [[United Nations Secretary-General]] [[Kofi Annan]] for bringing Africans together. Nevertheless, critics argue that, in its 39 years of existence, the OAU did little to protect the rights and liberties of African citizens from their own political leaders, often dubbing it as a "Dictators' Club"<ref>{{cite news|url=http://news.bbc.co.uk/2/hi/africa/2115736.stm|title=BBC News – World – Africa – African Union replaces dictators' club|first=Paul|last=Reynolds|website=news.bbc.co.uk|date=8 July 2002|access-date=8 August 2006|archive-url=https://web.archive.org/web/20120304011606/http://news.bbc.co.uk/2/hi/africa/2115736.stm|archive-date=4 March 2012|url-status=live}}</ref> or "Dictators' Trade Union".

The OAU was, however, successful in some respects. Many of its members were members of the UN, too, and they stood together within the latter organisation to safeguard African interests – especially in respect of lingering colonialism. Its pursuit of African unity, therefore, was in some ways successful.

Total unity was difficult to achieve, however, as the OAU was largely divided. The former French colonies, still dependent on [[France]], had formed the [[Monrovia Group]], and there was a further split between those that supported the United States and those that supported the [[USSR]] in the [[Cold War]] of ideologies. The pro-[[Socialist]] faction was led by Ghana's [[Kwame Nkrumah]], while [[Félix Houphouët-Boigny]] of the [[Ivory Coast]] led the pro-[[capitalism|capitalist]]s. Because of these divisions, it was difficult for the OAU to take action against states involved in internal conflicts because it could rarely reach an agreement on what was to be done.

The OAU did play a pivotal role in eradicating [[colonialism]] and white minority rule in Africa. It gave weapons, training and military bases to rebel groups fighting white minority and colonial rule. Groups such as the ANC and PAC, fighting [[apartheid]], and [[ZANU]] and [[ZAPU]], fighting to topple the government of [[Rhodesia]], were aided in their endeavours by the OAU. African harbours were closed to the South African government, and South African aircraft were prohibited from flying over the rest of the continent. The UN was convinced by the OAU to expel South Africa from bodies such as the [[World Health Organization]].

The OAU also worked with the UN to ease refugee problems. It set up the [[African Development Bank]] for economic projects intended to make Africa financially stronger. Although all African countries eventually won their [[independence]], it remained difficult for them to become totally independent of their former colonisers. There was often continued reliance on the former colonial powers for economic aid, which often came with strings attached: loans had to be paid back at high interest-rates, and goods had to be sold to the aiders at low rates.

The US and Soviet Union intervened in post-colonial Africa in pursuit of their own objectives. Help was sometimes provided in the form of [[technology]] and aid-workers. Despite the goodwill and best intentions, the OAU consistently failed at its stated goal - that of the fight to keep "Westerners" (colonialists) out of, and only focus upon, African affairs. The Organisation still heavily depended on Western help (military and economic) to intervene in African affairs, despite African leaders' displeasure at dealing with the international community, especially Western countries.

==Agencies==
Autonomous specialised agencies, working under the auspices of the OAU, were:

*[[Pan-African Telecommunications Union]] (PATU)
*[[Pan-African Postal Union]] (PAPU)
*[[Pan-African News Agency]] (PANA)
*[[Union of African National Television and Radio Organisations]] (URTNA)
*[[Union of African Railways]] (UAR)
*[[Organisation of African Trade Union Unity]] (OATUU)
*[[Supreme Council for Sports in Africa]]
*[[African Civil Aviation Commission]]
