The beatification of a Polish family who sheltered Jews during the Holocaust has given the government in Warsaw a chance to promote a one-sided narrative about attitudes of Poles in the war, experts have said.
Ahead of a ceremony on Sunday bestowing the Catholic honour on the Ulma family, who were killed by the Nazis, their story is being widely shared in Poland, with exhibitions, concerts and new books, including for children.
Presidential adviser Marcin Przydacz told Polish radio PR1 that the event has "a dimension of building up the image of Poland, and of historical truth".
Six million Polish citizens, including three million Jews, were killed by the Nazis.
The Yad Vashem memorial, which is dedicated to the memory of the Holocaust, honours 7,232 Poles as "Righteous among the Nations" for helping Jews during the Nazi occupation at a time when doing so was punishable by death.
- Heroic and tragic -
But historians say the sacrifice of those who helped Jews cannot be used to whitewash the past.
For years the authorities have denied the collaboration of some Poles with the Nazis and the indifference of a large part of the population to Jewish suffering.
"History is not a buffet where you can pick and choose what you want but that is how politicians are treating it," said sociologist Agnieszka Haska of the Polish Center for Holocaust Research.
"The story of the Ulma is heroic and tragic but cases of Jews being saved were not as numerous as politicised history now would have you believe... The Righteous were an extreme, just like those who collaborated," she said.
Haska said that "as victims of the Second World War, we are incapable of accepting that we were not as noble as we think."
For more than a year, the Ulma family hid eight Jews of the Goldmann and Grunfeld families in the village of Markowa in southern Poland.
Turned in by a Polish policeman, they were all executed -- including the children -- by Germans on March 24, 1944.
The mother was pregnant with her seventh child and began giving birth during the execution. The baby did not survive.
In 1995, the family were awarded the medal of Righteous among the Nations from Yad Vashem.
Since 2016 there has also been a museum in Markowa and the government has decreed March 24 the "National Day of the Memory of Poles who saved Jews".
- Patriotic discourse -
"Their story is used as a counter-argument to accusations of anti-Semitism and to polish Poland's image abroad," Zuzanna Radzik, an expert in Polish-Jewish dialogue, told AFP.
For her, the Ulma story "has become a choice excerpt for patriotic discourse because it was a family of peasants with many children and Catholic, which died."
Jan Grabowski, a Holocaust historian at the University of Ottawa, says, however, that after the execution of the Ulmas, 24 Jews in Markowa were killed by their Polish neighbours.
The example of the Ulmas allows politicians to make declarations not supported by historians.
Polish President Andrzej Duda in a speech in Markowa in March said that "thousands of the million Poles who helped Jews... were assassinated in this way", while Prime Minister Mateusz Morawiecki has said "millions" of Poles helped.
Historians estimate that around 30,000 Poles actively helped Jews.
"In Markowa, a village of 1,000 homes, around 20 Jews survived. It's not a lot" compared to 120 Jewish inhabitants before the war, said Grabowski.
Along with other Holocaust historians, including Barbara Engelking, Grabowski has become the target of various trials brought by government-financed bodies for "defamation" and "anti-Polish activities".
In June, Education Minister Przemyslaw Czarnek said he would cut financing for Holocaust studies carried out by Engelking at Warsaw University saying her research was of a "disgusting stupidity".
Grabowski said that exploiting the image of the Righteous serves to "hide the things Poles cannot face".
