From an essay by Stephen Lambden on Armageddon:
Armageddon as world war
On a number of occasions 'Abdu'l-Bahá spoke of Armageddon in connection with the "Great War"' of 1914-1918. In an address delivered at Stanford University in October 1912 he is reported to have stated,
We are on the eve of the battle of Armageddon, referred to in the 16th chapter of Revelation. The time is two years hence, when only a spark will set aflame the whole of Europe. The social unrest in all countries, the growing religious skepticism antecedent to the millennium are already here. Only a spark will set aflame the whole of Europe as is prophesied in the verses of Daniel and in the Book [Rev.] of John....
[33]
The first world war initiated something of a concrete "Armageddon." In a sense, the "Armageddon" of the first world war helped topple the Ottoman Turkish powers which had imprisoned Bahá'u'lláh and 'Abdu'l-Bahá (whom it planned to assassinate) and inhibited the spread of the religion they championed.
Interestingly, a military manoeuvre associated with the plain of Armageddon on 19 September 1918 ensured the safety of the then head of the Bahá'í religion ('Abdu'l-Bahá) who himself often visited the "Mount of Megiddo" (Mt. Carmel).
In 1920 General Allenby (who came to be entitled Viscount Allenby of Megiddo and Felixstowe) and his wife were taken by 'Abdu'l-Bahá to the Shrine of Bahá'u'lláh at Bahjí (near 'Akká, not far from Mt. Carmel).
[34] In his
God Passes By, Shoghi Effendi, summed up the effects the of "outcome" of world war I as "that tremendous struggle" in Palestine, yeilded the complete liberation of "the Heart and Centre of the [Bahá'í] Faith" from Turkish yoke.
[35]
For Bahá'ís, theories associating "Armageddon" and Mt. Carmel are of great theological interest since the Bahá'í world centre and certain sacred shrines are situated on this mountain. It could be argued from the Bahá'í writings that the "battle of Armageddon' has several senses; a semi-literalistic significance and a spiritual or transcendentalised meaning. The literal sense is related in Bahá'í sources to concrete 20th century warfare. A non-literal "Armageddon" is also expressed in the varieties of anti-Bahá'í persecutions; in concrete and "theological" attacks upon or controversies within this religion.
Since Megiddo is not far distant from the foot of Mt. Carmel, it could also be taken to be indicative of the Mt. Carmel-centered Bahá'í religion, "the Heart and Centre of the Faith"
[36] which is engaged in a spiritual battle of Armageddon ("Mt. Carmel") against the forces of irreligion.
Observing a regiment of soldiers from his hotel window whilst in Stuggart Germany in early April 1913, 'Abdu'l-Bahá is reported to have said,
The Bahá'í Grand Army consist of the invisible angels of the Supreme Concourse [
al-malá' al-a'lá]. Our swords are the words of love and life. Our armaments are the invisible armaments of Heaven. We are fighting against the forces of darkness. O my soldiers, my beloved soldiers!
Foward! Foward! Have no fear of defeat; do not have failing hearts. Our supreme commander is Bahá'u'lláh. From the heights of glory he is directing the dramatic engagement. He commands us! Rush foward! Rush foward! Show the strength of your arms. Ye shall scatter the forces of ignorance. Your war confers life; their war brings death. Your war is the cause of the illumination of all mankind. Your war means victory upon victory. Their war is defeat upon defeat...
[37]
The diffusion of the Bahá'í teachings is not infrequently spoken about in "militaristic" terms; in terms of an Armageddon-type conflict of "light" and "darkness." Before the first world war, Abdu'l-Bahá foresaw the victory of the power of truth; "For at the end the illumination of the Kingdom will overwhelm the darkness of the world..."
