The book "Great Britain and Argentina" by Klaus Gallo offers an in-depth analysis of the relationships between Great Britain and the Río de la Plata in the early 19th century. This period was crucial for the transformation of the region into the independent state of Argentina. Gallo highlights the initial ambiguities in British objectives, which included both conquest and military support. Despite this confusion, the relationship between Great Britain and the region evolved into a more stable partnership, particularly after the independence of the Spanish colony in 1810. The author examines the complex foreign policy implications for Great Britain, especially regarding the alliance with Spain, which ultimately led to the recognition of Argentina as a sovereign state.
