From 1935 to Estonia's incorporation into the Soviet Union in 1940, inmates condemned by civilian courts were given a choice to die either by poison-induced suicide or by hanging, as outlined in the Criminal Procedure Code (which took effect on 1 February 1935): "One hour before the scheduled time of the execution, the condemned shall be taken to a death cell, where the state prosecutor will read the death sentence and ask the prisoner whether he is willing to commit suicide. If the answer is in the affirmative, the prosecutor will hand the condemned a glass of poison—the kind of poison to be determined by the National Health Board. If the doomed man fails to take the poison within five minutes he will be hanged.'"[1] Military executions were carried out by a firing squad.
