Juan Peron died in July 1974, in the middle of his third and final term as president, having spent eighteen of the intervening years since his first overthrow in exile. By any ordinary measure, a political movement built this heavily around one charismatic leader's personal bond with organized labour should not have long outlived him. Peronism did more than outlive Peron: it splintered into factions that spent the following half century fighting, sometimes violently, over which of them held the true inheritance of a label its own founder had deliberately left broad enough to hold more than one meaning.
The seeds of that split were already visible before Peron died. By the early 1970s, Peronism as a mass movement contained both a revolutionary left wing, the Montoneros most prominently, who read justicialismo's third position doctrine as a genuine call to armed struggle against capitalism and imperialism, and a traditional labour-union right wing loyal to the older, corporatist model of state-brokered bargaining between capital and organized labour that had defined Peron's own first presidency. Peron's own return from exile in 1973 briefly reunited these currents around his person, but his death the following year removed the one figure both factions had claimed as their own, and the vacuum was filled first by brutal internal violence between them and then, in 1976, by a military coup that targeted the left Peronist current for elimination during Argentina's Dirty War.
Peronism's subsequent survival owed less to doctrinal continuity than to the same structural feature that had built it in the first place: a durable, personal claim on the loyalty of organized labour and the urban poor that any successor could inherit without needing to resolve the movement's internal contradictions. Carlos Menem governed in the 1990s as a Peronist while pursuing market liberalization Peron himself would barely have recognized; the Kirchners governed in the 2000s and 2010s as Peronists pursuing a left-populist program closer to the movement's revolutionary wing. What united these otherwise opposed governments was not a shared economic doctrine but the same claim to speak directly for Argentina's working people that Peron had first made in the 1940s, evidence that in Peronism the plebiscitary bond between leader and people has always mattered more than any single policy position built on top of it.
