The article is devoted to an overview and analysis of capital-intensive urban development projects undertaken in 18th century Istanbul, with particular reference to investment in commercial buildings. The questions of planning, funding, initiative and agency as well as the use of the traditional vakf instrument as the preferred funding mechanism are all addressed. The impact of this investment on macro-economic development patterns and the promotion of trade are also considered. Attention is also paid to the relationship (partnership) between public funding and private initiative assessing the degree to which competing sources for investment in urban development projects were able to work together harmoniously and coherently for the achievement of shared objectives.
