In 2025, the African Union and European Union celebrated 25 years of partnership. Leaders met at ministerial level on May 21, 2025, in Brussels, with a summit to follow in Africa. This milestone highlighted decades of cooperation on development, governance, and security between the two unions.
In 2023, the African Space Agency was officially formed under the AU's auspices, headquartered in Cairo, Egypt. This institution signified Africa’s ambitions in space science and technology, aiming to coordinate continental space policy, satellite development, and scientific collaboration at a continental level.
On January 31, 2017, Morocco, which had withdrawn from the predecessor OAU in 1984 over the Western Sahara dispute, officially rejoined the African Union. This marked a significant reconciliation and expansion of AU membership, underscoring continental unity despite complex territorial issues.
On July 29, 2015, U.S. President Barack Obama became the first sitting American president to address the African Union, speaking in Addis Ababa, Ethiopia. He praised progress in infrastructure and education, while urging democratic reforms, anti‑corruption measures, and inclusive governance across the continent.
In 2006, the African Court on Human and Peoples’ Rights was established to bolster the enforcement of human rights across the continent. It complemented existing rights bodies and demonstrated the AU’s progression toward institutionalized protection of human rights.
On March 18, 2004, the Pan‑African Parliament (PAP) was inaugurated in Midrand, South Africa. As the AU’s legislative body, the PAP aimed to provide democratic representation and enhance citizen participation across member states, reinforcing continental governance beyond executive summitry.
In 2003, the AU adopted a protocol to establish the African Court of Justice. Though originally separate, this court was later merged conceptually with the African Court on Human and Peoples’ Rights. It reflected the AU’s commitment to legal mechanisms for dispute resolution and human rights enforcement at the continental level.
On July 9, 2002, the African Union was officially launched at the first session of the AU Assembly held in Durban, South Africa. Thabo Mbeki, then President of South Africa, served as the AU’s first chair. The AU replaced the OAU and began operations with a renewed agenda for peace, governance, and integration.
On May 26, 2001, two-thirds of OAU member states ratified the Constitutive Act, allowing the African Union to be officially established. This marked the legal birth of the AU, transitioning from the OAU toward a union with broader vision for economic integration, governance, and institutional strength.
On July 11, 2000, in Lomé, Togo, the Constitutive Act of the African Union was adopted, laying the legal foundation for the AU. It codified the structure, aims, and organs of the future Union and served as the successor framework to the OAU for a revitalized pan‑African organization.
On September 9, 1999, African heads of state and government issued the Sirte Declaration in Sirte, Libya, calling for the replacement of the OAU with a more effective continental union. The declaration envisioned a body with stronger institutions, including a parliament, court, and economic framework to address modern challenges.
In 1991, the AEC was formalized under the OAU framework, designed to serve as a comprehensive plan for economic integration through regional blocs leading to a continental common market. This reaffirmed Africa’s commitment to more cohesive and coordinated economic development strategies.
In 1981, under the auspices of the OAU, the African Economic Community (AEC) was established to promote regional economic integration and development across the continent. The AEC represented a milestone in shifting focus from liberation struggles toward economic cooperation and shared prosperity among member states.
On May 25, 1963, thirty-two independent African states signed the Charter of the Organisation of African Unity in Addis Ababa, Ethiopia. The OAU was established to promote solidarity among African nations, facilitate decolonization, defend sovereignty, and coordinate African positions on global issues. It became a symbol of pan‑Africanism in the post‑colonial era.
Between April 15 and April 22, 1958, the First Congress of Independent African States was held in Accra, Ghana. This gathering of newly independent African leaders aimed to forge unity in the face of colonial legacies and led to the creation of “Africa Day,” an annual commemoration acknowledging the continent-wide liberation movement. The congress planted the seeds of pan-African institutional architecture that would ultimately lead to the OAU and AU.
