Francis Joseph (Franz Josef, 1830-1916), Emperor of Austria and King of Hungary, made a pilgrimage to Jerusalem in 1869. While in the Holy Land he failed to take the opportunity to inquire about Bahá’u’lláh Who at that time was a prisoner in Akká (Acre).
The Aqṣá Mosque, literally, the “Most Distant” Mosque, is referred to in the Qur’án,1 and has become identified with the Temple Mount in Jerusalem.
