Two student organizations at Lund University in southern Sweden were reported for hate speech last month following a party that featured "slaves" with blackened faces and ropes around their necks.
Jackson wrote a letter to Swedish Minister for Education Jan Bjorklund, decrying the incident and calling for an investigation, Swedish news agency TT reported.
"About a week ago a racist spectacle was held at one of your most respected institutions," Jackson wrote in the letter to Bjorklund.
Jackson urged Sweden to take methods to educate Swedes of the reality of the trans-Atlantic slave trade and the part Sweden played in it.
Bjorklund said he wouldn't comment on the incident until he personally reads Jackson's letter.
The European Network Against Racism in Brussels has written an open letter to Sweden's minister for democracy and European affairs, Birgitta Olsson, expressing its disgust at the incident.
The incident took an even nastier turn when the man who reported the incident was subjected to racial slurs, the report said.
