In Early Modern Age (XVIth and XVIIth centuries), the writing of ‘relações de sucessos’ [relations of events] became a strategic instrument in conflicting nations’ policies and in disputes for power across Iberian empires. This article aims to analyse the narrative of the Dutch War (1624-1654) found in Spanish-Portuguese relações de sucessos. It scrutinizes the contexts and political pressures to which these papers responded, the plotline they collectively formulate. Moreover, it focuses particularly on the voices of groups of interest behind the writing and printing of these pamphlets, in different moments and settings of the war.
