ARGENTINA has discovered 83 boxes of Nazi files filled with Hitler’s propaganda hidden in the Supreme Court’s basement.

The South American country has vowed to release the shocking secrets of the “ratlines” Hitler’s cronies used to flee Germany after World War II.

The bombshell discovery comes 84 years after the boxes arrived in Argentina.

In June 1941, the German embassy in Tokyo dispatched the boxes on the Japanese steamship “Nan-a-Maru”, as stated by the Argentinean Supreme Court.

German diplomatic representatives at the time claimed that the boxes contained personal items belonging to German people.

But the true contents of the boxes were soon uncovered, and they were confiscated by the Supreme Court.

These boxes allegedly included postcards, photographs, and propaganda material from the Nazi regime, as well as thousands of notebooks belonging to the Nazi party.

The Supreme Court remarked: “Upon opening one of the boxes, we identified material aimed at establishing and spreading Adolf Hitler’s ideology in Argentina during the Second World War.”

The boxes have now been transferred to a high security location where they will be examined for any clues about the brutal Nazi regime.

This comes after Argentina promised to declassify all government documents relating to Nazis who fled to the South American country after the war in March.

The documents are thought to contain details about the so-called “ratlines” that helped Nazis escape from Europe.

Argentina was a refuge for fleeing war criminals, and there have even been conspiracy theories that Hitler hid out there.

The maniacal Nazi leader died after shooting himself in the head on April 30, 1945.

Adolf Hitler is believed to have take his own life in the Führerbunker in Berlin after it became clear that Germany would lose the Battle of Berlin.

But in the months and years following his death conspiracy theories circulated over whether or not he actually died – and if he escaped instead.

It all began with the Soviet Union’s decision to seed two contradictory narratives in 1945: that Hitler died by taking cyanide or that he had survived and fled to another country.

Joseph Stalin himself even outright denied Hitler was dead when asked by US President Harry Truman.

It is known some Nazis used the “ratlines” to flee from Germany as the Third Reich collapsed.

Conspiracy theories about Hitler’s death run rampant even some 76 years after he shot himself in the Fuhrerbunker.

Secret documents reveal investigations into claims Hitler had a body double, U-boat sightings in Argentina, and claims that Adolf was photographed alive in Colombia.

One document reported to the FBI in 1947 even described a town called “Casino” near Rio Grande in Brazil which appeared to be “entirely populated” by Germans.

FBI agents interviewed an informant, who claimed to be a former French resistance fighter, who said he saw Hitler and Eva Braun sitting at a resort in the town.

Many notorious Nazis did manage to escape to South America, but it is accepted by history that Hitler and Eva Braun were not among them.

Josef Mengele was among this group, fleeing to Argentina where he lived for a decade.

He later moved from the Argentinean capital to Paraguay after Israeli Mossad agents captured Holocaust mastermind Adolf Eichmann, who was also living in the city.

Mengele died in Brazil in 1979 while swimming in a beach in the town of Bertioga.
