Biografia
Marta Macedo é, desde Setembro de 2022, investigadora no Instituto de História Contemporânea, Universidade NOVA de Lisboa. Licenciada em Arquitectura, concluiu o doutoramento em Arquitectura, especialidade Teoria e História, na Universidade de Coimbra em 2010. Antes de integrar o IHC foi investigadora no Instituto de Ciências Sociais, Universidade de Lisboa, no âmbito do projecto ERC The Colour of Labour: the Racialized Lives of Migrants, bolseira de pós doutoramento no CIUHCT, Universidade de Lisboa, e investigadora visitante na Universidade da Califórnia – Los Angeles.
O seu actual projecto de pesquisa, São Tomé e o Atlântico Global: uma genealogia para o Plantationoceno, aborda a relação entre as práticas técnico-científicas e a história imperial na longa duração. Mais concretamente, estuda a circulação dos sistemas de plantação entre São Tomé, Brasil, Angola e Congo Belga, cruzando abordagens da história da ciência e da tecnologia, do trabalho, do ambiente e do capitalismo.

The Organization of African Unity and the Struggle against Colonialism and Racism in Africa
The study of international organizations is an emerging field that covers a topic of growing importance in academia. In recent decades, the contributions of such organizations as actors in international relations have received increasing attention (Iriye 2004). Theoretical and empirical analyses seek to provide insights into the work of intergovernmental organizations, nongovernmental organizations, or transnational networks. By expanding their geographical scope beyond national borders, scholars interested in international organizations have reflected the myriad ways in which they can be studied (Hurd 2012).
The Organization of African Unity (OAU), as a regional organization, has been the subject of ongoing research (Gassama 2015). However, a review of existing publications reveals that relatively few studies have addressed the OAU’s solidarity against colonialism and racism in Africa. Several reasons may explain this situation. Comparatively, the OAU has received less attention than other international organizations, notably the United Nations. Research has mainly focused on its establishment and achievements in conflict resolution, cooperation and development (Muchie et al. 2014; Naldi 1999). Difficulties in accessing primary sources may also have contributed to the diversion of interest from the OAU’s contribution to decolonization and the end of white minority regimes.
Writing on the subject has mostly been done at the time of the events and lacks historical perspective (Binaisa 1977; El-Khawas 1978). The accounts are limited in scope, discussing primarily the OAU’s support for the liberation movements of Zimbabwe, Namibia and South Africa (Klotz 1995; Thomas 1996). With regard to the Portuguese colonies, with the exception of the work of Walraven (1999), it is difficult to find an overarching narrative, and the available information is mostly found in publications that do not focus on the topic as a primary concern (Sousa 2011; Tíscar Santiago 2013).
Thus, a more critical approach is needed to question what the OAU did to support the struggle against colonialism and racism in Africa, as well as the complexities and nuances involved. With this situation in mind, we intend to explore the OAU’s solidarity with the struggle against colonialism and racism in Africa in a workshop in-person and online that will take place in Lisbon, at the Institute of Contemporary History of the NOVA University of Lisbon, on 13 and 14 November 2025.
Call for papers
The workshop aims to place the OAU initiatives in their context and help consolidate analyses of its solidarity as a critical subject of the end of colonialism and white minority regimes. In addition, the workshop will contribute to rethinking the gaps in historiography by examining the OAU solidarity as a transnational phenomenon that transcended national boundaries.
We welcome proposals for 20-minute presentations on these and other topics:
- The extent to which the OAU played a role in ending colonialism and racism on the African continent;
- How the Liberation Committee was instrumental in the strategy of the OAU to undermine colonial rule and racist minority rule;
- How the attitudes of a number of states, due to inter-African competition, shaped the OAU’s policies on colonialism and racism;
- How the diplomacy of the OAU sought to shape the debate at the UN on colonialism and racism;
- How the OAU engaged with non-African countries as part of its support to the struggle for independence and against apartheid;
- How the organization worked as an intermediary in the support given by third parties to anti-colonial and anti-racist organizations;
- The importance of the relationship with the OAU for anti-colonial and anti-racist organizations to advance their agenda;
- The tensions and disagreements between the OAU and the anti-colonial and anti-racist organizations;
- The extent to which the anti-colonial and anti-racist organizations sought to use the OAU not only against the colonial and racist powers, but also to sideline competing groups.
Abstracts for presentations (200 words) and a biographical note (250 words) should be sent to: OAUconference@gmail.com
Deadline for submissions: 8 August 2025
Notification of acceptance: 15 August 2025
The organizers foresee the publication of the communications. The first draft of the papers is due on 30 January 2026.
