By 1939 the Anglo-Argentine Connection appeared to have been heavily reinforced as a by-product of the revision of British economic policy undertaken at the Ottawa Conference. Argentine government policy seemed intent on turning the republic into a quasi-Dominion or honorary member of the British Empire. Revisionism, with the object of unearthing British influence in Argentine affairs, was the new watchword, not only for a correct evaluation of the 1930s, but even to achieve a true understanding of the position of Rio de la Plata under the Spanish Empire. An influential treatment of the theme was developed by Carlos Ibarguren, who attacked prevailing interpretations of the Rosas period as a barbarous epoch in Argentine history and presented Rosismo as the embodiment of a conservative realism disastrously overthrown by unpatriotic liberals. In the export of Argentina's classic staple products, British firms in the River Plate failed to hold their position even in the trade to the British market.
