A running difficulty in African Studies (and beyond) is the need to reconcile modernity with difference, arising in attempts to account for the impact of colonialism as well as unequal international relations without lapsing into erasure of the manifold realities of African difference. Identifying the peasant vis-à-vis modernity as a salient instance of the problem, this thesis proffers a historical sociology of post-colonial Tanzania, where Julius Nyerere insisted that ‘If Marx were born in Tanzania he would have written the Arusha Declaration'. In saying so he was, in effect, pointing to the need, both programmatic and intellectual, to reconcile modernity and peasant-difference. Drawing upon international relations and the framework of uneven & combined development in particular, modernity is theorised as a process of fission whilst the peasant is cast as a protean subject thereof; the promised reconciliation can be achieved by rendering each as interactive. Building on this framework the main body of the thesis proceeds, encountering and engaging with the peasant-modernity problem along the way, to show the historical process by which a ‘citizen-peasant' social form emerged as combined development; an intellectual manoeuvre, moreover, that serves to conclude the reconciliation of ‘Marx' with ‘Arusha'. Chapters 1 and 2 establish the terrain and Chapter 3 supplies the methodological framework. Thereafter Chapter 4 sets out an account of the unevenness confronting Tanzania in the 1960s, linking that to its international relations in general and with China in particular to establish a pattern of interaction that Chapter 5 builds upon, revealing the Arusha Declaration as the starting point of a historical process from which the citizen-peasant arose, which is the key to the thesis as a whole. Chapter 6 completes the argument, pointing to the entrenchment of that form beyond its origins in the era of Nyerere's ‘African Socialism' taking the account up to the conclusion of the 20th century. Chapter 7 concludes, reflecting on the implications of the argument for the contemporary conjuncture.

This thesis is formed of three separate essays. The essays are empirical in nature and use the Kagera Health and Development Survey from Tanzania. The survey spans a 19-year period offering a unique opportunity to study many long-run dynamic processes of development in rural Africa. In the first essay, a version of which was co-authored with Joachim De Weerdt, we use these data to shed light on how mass internal migration changes the nature of informal risk-sharing. By quantifying how shocks and consumption co-move across linked households, our analysis shows that migrants unilaterally insure their extended family members who remain at home. This finding contradicts risk-sharing models based on reciprocity, but is consistent with assistance driven by social norms. Migrants sacrifice three to five per cent of their consumption growth to provide this insurance, which seems too trivial to have a stifling effect on their growth through migration. The second essay studies the role of exogenous income shocks on long-term migration decisions. The results reveal that temperature shocks cause large fluctuations in household consumption and inhibit long-term migration among men. These findings suggest that liquidity constraints are binding and prevent potential migrants from tapping into the opportunities brought about by internal migration. The final essay focuses on child nutrition and examines whether under-nourished children are able to recover the height losses later in life. The essay questions the methods used in the existing empirical literature and challenges the conventional view that recovery is nearly impossible after five years of age. The empirical part of the essay documents how puberty offers an opportunity window for recovery in the case of children in Kagera.

Tanganyika’s astonishing constitutional progress, achieved almost without friction, he's brought the country to the threshold of the political autonomy within a decade of organized African nationalism. July 7, 1954, was a historical day for it was then when the Tanganyika African National Union (T.A.N.U.) was born in Der es Zalasa, the country’s capital, with Julius K. Nyerere as president. From that day one, T.A.N.U. has struggled relentlessly for the independence of Tanganyika. Hence the significant constitutional changes announced in the Legislative Council by the governor, Sir Richard Turnbull, on December 15, 1959, represented an important achievement for the African nationalist movement. In a nutshell, his Excellency’s announcement purported that from September, 1960, after the second general election, Tanganyika would be self-governing to the extent that both in the Legislature and in the Council of Ministers the elected element would predominate. This thesis represents an attempt to open a new avenue in the study of African nationalism. It is an endeavor to analyze and trace the development of Tanganyikan nationalism. In exploring the entire vista of Tanganyikan nationalism, some fresh light might be thrown upon the peculiar trend of African nationalism in its Tanganyikan context. That would, in turn, help to reduce the the barest minimum the danger of highlighting either the surface similarities between the different versions of African nationalism in the way tourists sometimes tend to mislead students of African political aspirations of the apparent dichotomies between African nationalism which, when tested on the touchstone of reality, might be shown to be differences in degree rather than in kind.

Malgré le fait que le statut social soit reconnu comme ayant une forte influence sur l’aptitude, les facteurs affectant le statut social et les changements de ce statut demeurent peu connus. De plus, les études sur la dominance ayant un lien avec l’agressivité portent rarement sur des femelles. Nous étudierons ces aspects en utilisant Neolamprologus pulcher, un poisson à reproduction coopérative du lac Tanganyika. La probabilité d’ascension sociale était manipulée sur le terrain et les changements physiologiques et comportementaux, ainsi que le niveau plasmatique de testostérone, associé avec l’ascension à la dominance de femelles subordonnées étaient caractérisés. Le degré de coopération et la masse étaient supérieurs chez les femelles ascendantes par rapport aux femelles non-ascendantes d’un même groupe social. Après une semaine d’ascension sociale, les femelles ascendantes ne différaient pas comportementalement, mais différaient physiologiquement des femelles dominantes. Les femelles dominantes, ascendantes et subordonnées ne différaient pas quant au niveau de testostérone plasmatique. Comprendre les bénéfices des comportements coopératifs pour les subordonnés a longtemps posé un problème évolutif. Nos résultats impliquent que les comportements coûteux métaboliquement peuvent avoir été sélectionnés en améliorant l’aptitude future via l’héritage du territoire et du statut social. De plus, le degré de coopération pourrait être un signal de qualité détecté par les compétiteurs et les collaborateurs. / Although social rank is known to have a strong influence on fitness, factors affecting rank and changes in rank remain poorly understood. In addition, studies of dominance and its relation to aggression rarely focus on females. We address these issues in this study using Neolamprologus pulcher, a cooperatively breeding fish species from Lake Tanganyika. The probability of social ascension was manipulated in the field and the physiological and behavioural changes as well as plasma testosterone level associated with subordinate female ascension were characterized. Both helping effort (degree of cooperation) and body size were greater in ascending versus paired same social group non-ascending females. After one week of social ascension, ascending females did not differ behaviourally but were physiologically different (higher body condition, smaller, lighter) from dominant females. Dominant, ascending females and subordinate females did not differ in plasma testosterone levels. Understanding the benefits of helping behaviour for subordinates has long been an evolutionary challenge and our results imply that this costly metabolic behaviour may have been selected by enhancing future fitness via territory and rank inheritance. Furthermore, helping effort could be a signal of quality detected by both competitors and collaborators.

Hemed Abdallah el-Buhry (1850-1928), known as Mzee Kibao and coming from a prestigious family of poets from Tanga, can be considered as the inventor of a new relation between poetry and reputation in the context of the German conquest of Tanganyika. The aim of this paper is to analyse how the ap¬parently anti-epic attitude of ‘reputation through non-action’ is the main narrative device of Hemed’s tenzi. This poetry of ‘prevented actions’ can be considered as an important turn in Swahili poetry in the new historical context of colonisation.

My thesis focuses on the experiences of people with albinism in higher education (HE) in Tanzania. Albinism is a genetically inherited condition and it affects people of all ethnic backgrounds worldwide. In Tanzania, the condition affects one in every 1,400 people. People with albinism in Tanzania often face social discrimination, superstition, and prejudice including murder threats due to myths and beliefs that their body parts are a source of wealth and prosperity. They also experience physical challenges including threats from the African tropical sun and visual impairment. All these factors interact with educational opportunities. Information about the oppression, killings and amputation of body parts of people with albinism in Tanzania has been widely reported in the media globally. However, albinism remains socially under-researched and under-theorized – especially in relation to how it interacts with HE opportunity structures. This research attempts to contribute to existing literature and construct new insights into albinism and HE. In so doing, I draw upon a range of theoretical approaches including Sarah Ahmed's concept of affective economies and fear of difference, Margaret Archer's notions of the internal conversation and reflexivity as well as various established feminist theorists such as Simone de Beauvoir to analyse and explain issues arising from the study including misogyny. I also draw upon Pierre Bourdieu's concept of symbolic violence. My research is a case study of albinism in HE in Tanzania. Using qualitative methods I draw upon feminist methodological approaches, values and principles to explore albinism and explain what constrains and enables students with the condition to interact with HE opportunities. The data for this research were collected from 35 participants in Tanzania, namely: 14 students with albinism (involving current and graduate students with albinism); six teaching staff and five HE support staff members. Other participants included officials from four non-governmental organisations (NGOs), four government officials, one parent and one student reader/note-taker. I conducted 19 face-to-face semi-structured interviews with six current students with albinism, three teaching staff, four NGO officials and four government officials. Likewise, I conducted face-to-face semi-structured interviews with one parent and one student reader. I also conducted one Skype interview with a current student with albinism as well as three focus groups discussions with 14 participants. The first group was of seven graduates with albinism, the second involved three teaching staff and the third was of four HE support staff. I also used desk-based research methods, conducting telephone conversations with 52 statistics officers in order to investigate where students with albinism are located within HE in Tanzania. Looking at literature and my research questions, the data were then compared across different participants and universities to establish patterns and common themes among them. The findings from this research indicated that the systems of power that work to oppress people with albinism are multifaceted with structural, cultural and socio-economic conditions. Some key findings included how people with albinism were subjected to misogyny, myths and fear of the ‘other'. However, the 14 students with albinism in this study demonstrated a high level of agency, creativity, autonomy and motivation to improve their lives and thus overcome discriminatory social structures, oppression and harassment. They also illustrated their commitments to contribute usefully to society despite the constraints and limited support that they often encountered. Access to HE was seen as a major way to transform their identity by challenging deeply ingrained social prejudices, which often label people with albinism as having limited cognitive capacity. The implications of this research are that government commitment will be required in order to allocate sufficient funds to promote awareness of, and create change about, albinism and the elimination of household poverty, particularly that of female-headed households (FHH), as well as to adequately finance HE institutions so they can put in place support services and arrangements for students with albinism.
