However new findings and documents uncovered by research experts revealed that the Roma death toll was at least about 200,000 to 500,000 of the 1 or 2 million Roma in Europe, although there are numerous experts and scholars who give much higher number of Romani deaths, such as Ian Hancock, director of the Romani Archives and Documentation Center at the University of Texas at Austin, in his findings discovered that almost the entire Romani population was killed in Croatia, Estonia, Lithuania, Luxembourg, and the Netherlands. Rudolph Rummel, the late professor emeritus of political science at the University of Hawaii who spent his career assembling data on collective violence by governments toward their people (for which he coined the term democide), estimated that 258,000 must have been killed in Europe, 36,000 in Romania under Ion Antonescu and 27,000 in Ustaše-controlled Croatia.
