The session of September 20th was organized so that the new states could participate from the beginning. Frederick H. Boland, elected president of the General Assembly at that meeting, proposed addressing the nominations recommended by the Security Council. The official record shows the delegations entering the chamber to applause from the representatives.

Cameroon, Togo, Malagasy (now Madagascar), Somalia, Congo of Léopoldville (now the Democratic Republic of Congo), Dahomey (now Benin), Niger, Upper Volta (now Burkina Faso), Ivory Coast, Chad, Congo of Brazzaville, Gabon, and the Central African Republic were admitted. Cyprus was the fourteenth new member admitted that afternoon by the General Assembly.

The concentration of thirteen African admissions on the same day gave symbolic force to the moment. Each candidacy had followed its own path, but the succession in the plenary session made visible the dimension of change in Africa. The delegations occupied their designated seats before former colonial powers and countries involved in the disputes of the Cold War.

There is a certain accuracy in the memory of the episode. There was no single vote to admit all these countries to the UN. The Assembly considered separate draft resolutions, numbered 1476 to 1489, and approved each admission by acclamation, without a roll-call vote. The sequence in the plenary session created the appearance of a collective entry.

There was also an absence. The Federation of Mali was among the candidates, but Boland reported that some delegations were not ready to decide due to political circumstances. The federation between Senegal and the Sudanese Republic had dissolved in August. The matter was postponed, and both would be admitted on September 28.

The first day was more complex than a bloc vote. The UN applied the state-by-state admission procedure at an exceptional pace. In a few hours, the colonial map of Africa lost indirect representation and gained thirteen sovereign voices in the world forum, facing colonial powers and new allies.

The scale of the change is evident in the numbers. The UN had 82 members in 1958 and maintained that total until 1960. By the end of that year, it had grown to 99. Of the seventeen new members, sixteen were African and one was Cyprus. By 1961, a United Nations document already recorded 26 African members.

In the General Assembly, this growth had a direct effect because each state has one vote. Countries with very different populations, wealth, and military strength were on the same formal level. The African increase did not change the power of the Security Council, but it gave the continent more weight in the most representative body.

The new presence also changed the formation of majorities. Resolutions, elections, and recommendations came to depend on an Assembly with more African governments. Africa ceased to appear primarily as a territory under tutelage or a colonial issue and began to participate directly in internal decisions, candidacies, and negotiations at the UN.

Diplomats from other regions noticed the change before the session. In June 1960, a U.S. State Department instruction predicted that the new admissions would make Africans the largest geographic group in the UN, surpassing Latin Americans. This prediction shows how much the change was already being treated as a strategic issue.

This did not create a single African position. The new states arrived with distinct ties to former colonial powers, their own plans, and different interpretations of the Cold War. Some sought autonomy between the blocs, others maintained European ties, or sought support from Washington, Moscow, and other capitals. Number provided leverage for negotiation.

The main change was structural. Before 1960, much of Africa appeared at the UN as a territory under trusteeship or a colonial issue. After the wave, countries began to occupy seats, present proposals, vote, and compete for positions. Decolonization also began to change borders and the daily arithmetic of multilateral diplomacy.

Entry into the United Nations had a symbolic force that bilateral independence did not produce. The new state ceased to depend on recognition from former powers or neighbors and became part of an organization founded on the sovereignty of its members. The location, the plaque, and the vote materialized this legal change.

The procedure also showed that international sovereignty has rules. Article 4 of the Charter establishes that admission depends on a decision by the General Assembly following a recommendation from the Security Council. On September 20, the African candidates already had this recommendation, and the Assembly concluded the admission process.

For leaders who had achieved independence in different contexts, the UN offered a common platform. There they could address former colonial powers, vote on territories, participate in committees, and seek support for development, security, or external recognition. Formal equality altered who could speak for the state.

At the next plenary meeting, the Indonesian representative stated that former rulers and former ruled recognized each other as equals and full members of the community of sovereign states. It was a diplomatic reading, not a description of material equality. Still, it accurately captured the essential rupture caused by the new African presence.

This gain in representation had limits from day one. The Security Council retained a structure concentrated in the permanent members, and economic power remained unevenly distributed. Many African states faced weak institutions, inherited borders, and external dependencies that mere admission to the UN could not fully resolve.

The 1960 reforms did not eliminate these tensions nor erase the asymmetries between states. However, they gave sovereign African governments their own space to present national problems as international issues, seek alliances, and contest decisions. Sovereignty also began to have a visible presence and its own voice in the multilateral system.

The African vacancy entered the UN at the height of the Cold War. Washington and Moscow followed every new government and every possible vote in the General Assembly. By 1960, US documents were already treating African expansion as a shift between regional groups. In the same session, the Soviet Union presented a proposed declaration on colonial independence at the UN itself.

The context made the dispute concrete. Three days before the opening of the 15th session, the Security Council had convened an emergency session of the General Assembly on the crisis in Congo. The new Congolese state, independent since June, became a member of the UN while facing a political crisis, external intervention, and a United Nations operation already underway on its territory.

The new delegations did not enter as unified groups. Some had close ties with France or the United Kingdom, others advocated tougher lines against colonialism, and several sought a middle ground between the blocs. A US analysis acknowledged that Africans consulted with each other, but said that these positions did not bind all African governments at the UN.

This autonomy increased the value of each vote. In the General Assembly, the powers had to form majorities instead of presuming old colonial loyalties. Congo, apartheid, disarmament, decolonization, and representation were now debated there before more African governments, leading actors to negotiate with states that, until recently, did not even have their own seat at the UN.

Therefore, September 20th did not simply mark a transfer of votes from one side to the other. It marked the entry of new decision-making centers into a system dominated by competition between great powers. The Cold War continued to shape alliances and pressures, but decolonization added African national interests that did not always fit within the division between the West and the Soviet bloc.

The political effect of the new composition became apparent in the same session. On December 14, 1960, the General Assembly approved resolution 1514, the Declaration on the Granting of Independence to Colonial Countries and Peoples. The text affirmed the right of peoples to self-determination and called for an end to colonial rule. It was approved by 89 votes, with no votes against and nine abstentions.

The declaration did not arise solely from the admissions of September. The anti-colonial debate was already mobilizing Asian, Arab, African, and Latin American states. The project was presented by Cambodia on behalf of 26 Asian and African countries and later gathered 43 sponsors. The African wave, however, gave greater prominence to governments with recent sovereignty and reinforced the political weight of the issue.

The result shows this new arithmetic without allowing for automatic interpretation. Among the votes in favor were many of the African states admitted that year, but also countries from other regions. Australia, Belgium, the Dominican Republic, France, Portugal, Spain, the Union of South Africa, the United Kingdom, and the United States abstained. No member voted against the text approved by the Assembly.

Resolution 1514 became a central reference point for decolonization at the UN. Its significance was linked to who occupied the room: peoples previously treated as colonial dependencies began to participate as states in defining norms for territories still lacking independence. This newfound sovereignty thus began to directly influence the formation of new diplomatic majorities.

This was one of the lasting effects of 1960. Decolonization ceased to be a matter conducted primarily by the administering powers and began to be organized by a large coalition of post-colonial states. Their positions were not identical and national interests could diverge, but the center of gravity of the discussion could no longer ignore newly independent Africa and Asia.

For the African territories under Portuguese administration, the change at the UN had an immediate effect. On December 15, 1960, the General Assembly approved resolution 1542 by 68 votes to six, with 17 abstentions. The text dealt with Portugal's obligation to transmit information under Chapter XI.

The resolution listed Angola, including Cabinda, the Cape Verde archipelago, the then Portuguese Guinea, São Tomé and Príncipe, and Mozambique. It also included Macau and Timor. For the UN, these territories were covered by the regime applied to non-self-governing territories. Portugal was required to provide information on the conditions on the ground.

The Portuguese government rejected this interpretation. The vote took place in an Assembly already transformed by the African admissions of September. Several of the new states supported the resolution and, in the following years, began to participate in debates on Portuguese colonialism, increasing African influence on a matter that Lisbon considered to be of an internal nature.

The 1960 wave did not lead to the independence of the Portuguese colonies. However, it altered the diplomatic landscape on which Lisbon defended its position. More African governments had a vote, presence, and initiative in the UN, while self-determination and decolonization gained prominence among the issues debated by the General Assembly in that decade.

For Angola, Guinea-Bissau, Cape Verde, Mozambique, and São Tomé and Príncipe, this change had historical significance. Issues ceased to be treated solely as internal Portuguese matters and began to be examined within an international framework. Pressure from the UN would subsequently increase, alongside armed struggles and Portuguese transformations.

The connection to the PALOP countries today is direct, but not linear. Independence would only arrive between 1974 and 1975, after distinct processes. In 1960, new African states entered the scene and helped to change the political rules of the discussion about territories that remained under Portuguese colonial rule in Africa.

Sixty-six years later, September 20, 1960, remains a date of institutional rupture. The memory gains precision when one abandons the idea of ​​a single vote: thirteen African states and Cyprus were admitted by separate decisions in the same session, while Senegal, Mali, and Nigeria joined in the following weeks.

The agreement permanently altered the composition of the United Nations. This entry did not eliminate power inequalities nor create a uniform African voice. However, it changed who could vote, propose texts, and demand that colonialism and self-determination be treated as central issues of the international order.

For Africa and for the future PALOP countries, the transformation was also diplomatic: sovereignty ceased to be merely proclaimed in newly independent capitals and began to occupy seats, form majorities, and exert pressure on the structures of the multilateral system.
