To what extent did ideological appeal aid the rule of Perón?
Peron was more of a pragmatic thinker than one who defiantly relied on any ideology. If there was an ideology that played a role in both his rise to power and his demonstration of it when he held it, it his belief of dictatorship.
Peron did much to ensure that his consolidation of power as leader of Argentina was unquestioned. Peron forged alliances with the working class, but he did little to prove himself their friend while in office. His philosophy of Justicialismo appeared to be quite muddled except for the reliance on his own notion of power and ambition to be so closely identified with the execution of power.
Inspired by the Fascist ideology of Mussolini and Hitler, Peron understood the ideological advantage of a cult of personality, being overwhelmingly identified with political rule, as a way of crowding out the voices of dissent. The nationalism that he invoked extended his dictatorship rule by ensuring that he symbolically embodied the nation.
Peron did not build a government or set of policy initiatives that could be easily identified with one particular ideology. This reflected his own sense of pragmatism within a construction that would make him the center of governance. In this, one can see the ideological penchant for dictatorship within Peron's rule.
