1.NounA tax paid by bloodshed; especially, a derogatory term for military conscription.
""France is the mother of Conscription. What has she gained by that blood-tax?"; "I appeal to the working men of Great Britain..not to be misled by catch-phrases about ‘the liberty of the subject’ and the ridiculous cant about a ‘Blood Tax’!"; "They would have paid their blood-tax, done their own part in the immemorial human warfare against nature.""
