Paraguay

Paraguay occupies two connected roles in the account of Josef Mengele’s escape: it is a landscape he first approaches as an agricultural salesman, and later a refuge whose citizenship and political protection obstruct attempts to bring him to justice. German farming settlements, networks of influential allies, and the government of Stroessner make the country useful to Mengele. Yet his departure for Brazil does not end Paraguay’s importance. Its citizenship records, its resistance to extradition, and the uncertainty surrounding its protection of him keep the country at the centre of the pursuit.

Market, landscape, and German networks

Mengele’s first sustained interest in Paraguay is commercial. With support from his father and Hans Sedlmeier, he is allowed to front the family business in Argentina and investigate the South American market for agricultural machinery. Uli Rudel takes him to Paraguay, where German farming colonies create prospective customers for equipment ranging from wheelbarrows to combine harvesters. The fertile southeastern meadows, and the need for agricultural tools and fertilisers, suggest that the market could be substantial. Rudel also presents the country as safe and socially connected: he has numerous friends in Villarrica, where the first Nazi Party outside Germany was founded in 1927.

Mengele’s later journeys deepen this business network. Accompanied by Heinrich Lyons and catalogues of agricultural machinery, he travels through a green agricultural belt set among scrubland, palm savannah, and the treeless expanse of Gran Chaco. Maté and cotton fields draw him across the country; he visits cattle farmers, Mennonite communities, and the descendants of the founders of Nueva Germania. What began as market research becomes a set of relationships extending across Paraguay. The connections also bring him closer to people with political and military influence.

Among these allies is Frederico Haase, whose wife is the daughter of a man who became finance minister after Stroessner seized power in the May 1954 coup. Haase introduces Mengele to Werner Jung, a former leader of Paraguay’s Nazi youth group. Through Rudel, Mengele also befriends Alejandro von Eckstein, an exiled Baltic baron who serves as a captain in Stroessner’s army and as the dictator’s close military associate. These networks make Paraguay more than a prospective sales territory: they offer contacts, local knowledge, and potential protection.

From contingency plan to place of refuge

As Argentina’s economic and political conditions worsen, Mengele considers Paraguay a possible hideaway if the Peronist government collapses. In 1953, an assassination attempt nearly kills Juan Perón, while inflation, strikes, and falling wages compound the instability. Mengele’s earlier Paraguayan connections therefore acquire a second value. The country is not simply a place to sell machinery; it is a nearby alternative if his position in Argentina becomes untenable.

That contingency becomes urgent after legal pressure builds in Argentina. On 25 February 1959, a court in Freiburg im Breisgau issues an arrest warrant for multiple cases of premeditated murder and attempted murder. When Hans Sedlmeier relays the news, Mengele must sell his villa and shares in Fadro Farm, close his bank accounts, and leave. He parts from Martha Mengele and Karl-Heinz, who remain in Argentina for the time being, and heads to Paraguay. The prospect that Argentina’s new government might grant an extradition request makes delay dangerous.

Rudel helps arrange his next steps. He turns to Alban Krug, who owns a farm in the Nueva Bavaria enclave near the Argentine border, after Mengele asks to stay in a German community rather than a large city. Mengele also settles in Asunción, where Alejandro von Eckstein and Werner Jung receive him, and where allies assist with legal representation and a naturalisation application. The application is irregular: Paraguayan citizenship requires five years of residence, which Mengele has not completed. The political utility of the relationships is evident when the extradition process begins. Rudel tells the Paraguayan interior minister that Mengele is being pursued in Germany for his political beliefs and would be useful to Paraguay, urging that his naturalisation be expedited.

In November 1959, Paraguay grants Mengele citizenship, a residence permit, a certificate of good behaviour, and an identity card. The papers transform a refuge into a form of state-recognised protection. At a small celebration in the home of the Jungs, however, the news is overshadowed by the death of Mengele’s father, Karl Mengele. The episode links the security he has obtained in Paraguay to the family support on which his flight has depended: his father had continued to shield him, and Mengele experiences the loss as the loss of an indispensable ally.

Extradition, sovereignty, and obstruction

The effort to extradite Mengele crosses several jurisdictions and repeatedly stalls. West Germany’s request travels through Argentine offices, where procedural obstacles and delays accumulate. A further request is sent to Asunción, and Interpol seeks a copy of Mengele’s naturalisation file. The Paraguayan authorities are therefore aware that extradition is approaching, but Rudel intervenes with the interior minister. The intervention helps turn the citizenship application into an urgent political matter rather than an ordinary administrative one.

In 1962, West Germany requests Mengele’s extradition from Paraguay. Stroessner refuses to cooperate, although Rudel has informed him that Mengele has left for Brazil. Paraguay’s position is framed around national sovereignty: Stroessner indicates that even if Mengele were arrested on Paraguayan territory, he would not be surrendered to a foreign power. The distinction between the country’s formal claim to protect a citizen and the uncertainty about Mengele’s actual location complicates the pursuit.

The dispute continues in 1963, when Chancellor Konrad Adenauer pledges ten million US dollars in aid if Paraguay delivers Mengele. Stroessner rejects the offer. In 1964, as the Frankfurt Auschwitz trials draw international attention, West Germany publicly states that Mengele is a Paraguayan citizen living in the tri-border region and travelling frequently to Brazil. Its ambassador asks Stroessner to revoke the citizenship on the ground that it was obtained through false information. Stroessner answers that Mengele has long since left and treats the request as an unacceptable interference in Paraguayan sovereignty. When prosecutor Fritz Bauer announces a 50,000-mark reward for Mengele’s capture, Paraguay’s interior minister counters that he is hiding in Brazil or Peru. A former SS officer’s later claim to have encountered Mengele in Paraguay further undermines the government’s denials, but does not produce his arrest.

A retreat in the pursuit and a lasting association

By 1965, West Germany appoints a new ambassador to Asunción with instructions to improve relations. Paraguay matters to West German foreign policy as well as to the Mengele case: it has a large population of German descent and is considered important to Western efforts to contain Marxist guerrilla movements in South America. The Federal Republic eases pressure over the fugitive. The pursuit is weakened not by a resolution of the legal dispute but by competing diplomatic priorities and the limits of cooperation between states.

Paraguay’s role also changes after Mengele leaves. In September 1960, as Mossad monitors his family and approaches Krug’s farm, Mengele decides to disappear. Uli Rudel supplies a Brazilian identity card under the name Peter Hochbichler, and Krug and Rudel drive him to the Brazilian border. Mengele burns his German passport and notes and destroys his Auschwitz specimens before crossing. This departure means that Paraguay is no longer his principal place of concealment, but its citizenship continues to shape the search: West German authorities focus on Paraguay after receiving documents that attest to his naturalisation, and Stroessner’s refusal leaves the country an enduring point of contention.

The connection persists into the later public hunt. Paraguay revokes Mengele’s citizenship in the summer of 1979, but in 1985 many still believe that he is living there under the protection of Stroessner’s associates. Beate Klarsfeld protests outside the presidential palace in Asunción, while competing claims place Mengele in several South American countries and even beyond the continent. Paraguay consequently remains both a documented part of his escape and a screen for speculation about his whereabouts. Its significance lies in that double history: agricultural routes and personal alliances helped him enter its orbit, and citizenship, sovereignty, and diplomatic hesitation helped prevent that orbit from yielding an arrest.
