The practice of beheading dates back to Greek and Roman times. The Roman Empire used it for its own citizens while crucifying others. Beheading has been traditional in Europe since the Middle Ages. In Scandinavia, it was customary to behead a nobleman by sword (a noble weapon of war), but a commoner by axe. Beheading was abolished in Britain (1747), in Denmark (1892), in Sweden (1902), and in Norway (1905). With the exception of the UK, All European countries that previously beheaded have not totally abolished the death penalty.
China also used it widely, until the communist regime replaced it with shooting in the 20th century. Japan beheaded up to the end of the 19th century, then turned to hanging. The Nazis used the guillotine-like Fallbeil in Germany and Austria between 1933 and 1949 (E. Germany, 1966) on an estimated 16,500 persons who were considered common criminals and traitors.
Beheading is a “sacred Islamic Jihadi practice.” Endorsed by the Qur’an, and performed by most Islamic rulers, it continues to this day as the most brutal and degrading method of killing infidels – Jews, Christians, Hindus, and anyone considered a polytheist.
Quranic verses dictate beheading Kaffirs. One example is 5:33-“The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is:execution(by beheading), or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter.”
The most virulently intolerant Islamic dictatorship in the world is The Kingdom of Saudi Arabia, that spreads and promotes (fundamentalist) Wahhabism worldwide – incites and encourages Jihadis to hate and behead thousands of non-Muslims and other infidels, freely and without remorse – and does so to this day.
