Beginning in September 1867, Bahá'u'lláh wrote a series of letters to the world leaders of His time, addressing, among others, Emperor Napoleon III, Queen Victoria, Kaiser Wilhelm I, Tsar Alexander II of Russia, Emperor Franz Joseph, Pope Pius IX, Sultan 'Abdul-Azíz, and the Persian ruler, Násiri'd-Dín Sháh.
In these letters, Bahá'u'lláh openly proclaimed His station. He spoke of the dawn of a new age. But first, He warned, there would be catastrophic upheavals in the world's political and social order. To smooth humanity's transition, He urged the world's leaders to pursue justice. He called for general efforts at disarmament and urged the world's rulers to band together into some form of commonwealth of nations. Only by acting collectively against war, He said, could a lasting peace be established.
Continued agitation from opponents caused the Turkish Government to send the exiles to Acre, a penal city in Ottoman Palestine. Acre was the end of the world, the final destination for the worst of murderers, highway robbers and political dissidents. A walled city of filthy streets and damp, desolate houses, Acre had no source of fresh water, and the air was popularly described as being so foul that over flying birds would fall dead out of the sky.

"You may listen to the audio books on your computer, download them onto an mp3 player or record them onto a tape (45 minute per side) by plugging your cassette recorder into the headphones jack on your speakers. Unfortunately, we have not devised an order to the list. Thanks to the US's and UK's Bahá'í Service for the Blind for allowing us to use these tapes! The recordings are in the process of being re-digitized at a higher quality level. The file sizes are larger but the quality is significantly better. So, even you have heard them before, you might want to listen again."
