From 1880 to 1930, Argentina received hundreds of millions of pounds of British investments, making it in an economic sense a British dominion. The world economic crisis of the 1930s forced both Britain and Argentina t o reconsider many of these economic ties. The changing Anglo-Argentine relationship is reflected in the complex relations between a British tramway company, the Anglo Argentine Tramways Co. Ltd., that operated in Buenos Aires and the Argentine national government between the onset of the Great Depression and the early 1960s. The Anglo, as the company was popularly known, was the main tramway concern diat offered public transportation and contributed to the urban development of a cosmopolitan Latin American metropolis until 1914. Second, the history of the company illustrates political and economic problems that plagued the links between foreign public utilities and the host government from the 1930s onwards. Third, since the Anglo belonged to SOFINA, a transnational holding company with worldwide investments in public transportation and electric power stations, our case study shows the limitations of Sofina's political power in Britain and Argentina.
