Dr. Sufflay led a political party which had reportedly not managed to win more than a few seats in the 300-strong legislative.
Sufflay was beaten to death with a steel rod on February 18 1931 in Zagreb. This was during the Yugoslav royal dictatorship, so Croats thought that his death had a political background and blamed it on the Serbian police.
Following his death, Albert Einstein and Heinrich Mann sent a letter to the International League of Human Rights in Paris appealing for protection of Croat scientists from the Serbian regime.
