This is going to be a hard question to answer in a manner that is up to the sub's standards. What you can do is search the sub for questions about the Roma people, and from there infer that many of the same biases that exist against the Roma in Europe in the past and still today, probably applied to academic areas of study as well. This is also a question that is going to be hard to answer because of national, regional, and local variations in education standards. For instance, I distinctly remember from my years in high school that the three primary groups targeted by the Holocaust were Jews, homosexuals, and the Roma. Your experience is obviously different. These variations are difficult to take into consideration on a question such as this.
u/commiespaveinvader touched on the topic a bit here
u/estherke and u/yodatsracist also discuss the issues facing the Roma and your question more directly here
When the subreddit was young, /u/estherke and /u/yodatsracist answered Why did West Germany deny including Romani in the holocaust until 1979 when they have been so upfront about the genocide against the Jewish population?

Having studied this same question before, I can tell you that the answer is multi-faceted and has many driving factors behind it. According to Zoltan Barany of the University of Texas, since the end of World War II, Jewish persecution has been the primary focus of Holocaust studies. Additionally, compared to Jewish people, the genocide of Romani people was far less meticulously documented by the Nazis, and by Roma themselves, many of whom did not have the same education as their Jewish counterparts to write diaries or memoirs of their experiences. There are however a few notable exceptions such as Philomena Franz, who was the first Romani person to publish their journal on her experiences in the concentration camps and was instrumental in the official recognition of the Romani Holocaust in the 1980s by Germany. Moreover, there is a general lack of public awareness of the Romani people compared to other ethnic groups, Romani people lack the proper facilities to conduct our own large-scale Holocaust research and very few Romani-origin Historians that specialize in Holocaust studies exist (Barany 1998: 10).
It is important to note that this exclusion is not by any means recent. During the Nuremberg Trials that began in 1945, not a single Romani person was called to testify (Hancock 2013: 10). Anti-Romani persecution and racism did not begin with the Holocaust and it most certainly did not end there. After the Holocaust, the pre-Nazi laws were put back into place, therefore many Romani survivors were scared to come forward as they would have been put back into detention centers (Hancock 2013: 10). Anti-Romani racism has been a key factor in the exclusion of Romani people from Holocaust remembrance. For example, in 1951, Germany, despite overwhelming evidence to the contrary, ruled that Romani people were not targeted on a racial basis, but rather because they were criminals and asocials, and therefore were not eligible to receive compensation (Hancock 2013:10).
In summary, as noted by Dr. David Crowe in a publication on Roma and Sinti by the United States Holocaust Memorial Museum, the lack of Romani recognition is tied to the “greater failure of scholars to investigate the history, culture, language, and ethnicity of the Roma” as well as “a marriage of prejudice and the law that is almost as old as the 800-year-old Roma presence in Europe. (Crowe 2002: 81-83)” Additionally, Crowe expands upon Barany’s point in saying that because a lot of the Romani victims of the Holocaust laid outside of the territory of Nazi Germany, such as in places like Romania and Hungary, the lack of proper documentation in those areas is an added layer to the lack of proper understanding of the number of Romani victims and the varying amounts of estimates. Lastly, as noted by all 3 historians, us Romani people have a general distrust of non-Roma, and because of this we have been hesitant to share our experiences, especially in courts of law due to the historical persecution of our people. As a Romani person myself, I have noticed this in my own communities, although there has been an increasing uptick of young Roma activists that gives me hope for more recognition in the future. I hope this was helpful and I highly suggest checking out the historical sources linked here for more detail as well as the journal of Philomena Franz.
