t it is reasonable to speculate that Baha'u'llah may been influenced by European thinkers. Arguments in support are His father's position as a minister of the court of the Shah, so perhaps some association with European powers, then His exiles to Bagdad, Constantinople, Adrianople, and eventually to Akka.
Yes, he knew a great deal about European religion, philosophy, society and politics. The worlds were not hermetically sealed. He was multilingual, and would have had more access to europe through Arabic translations and discussions than through Persian, but even in Persian there were travel diaries of progressive thinkers to consult.
The first Persian writer to mention is Mir Abdu’l-Latif Mosavi
Shushtari (1759-1805), a Persian from a clerical family with a traditional religious education who later became a merchant and travelled to India. His travel diary for those years (1798-1801)
Tuhfat al-‘`Alam was written in 1801 after his return to Iran, with an addendum added in 1804. As well as noting astonishing facts about India – such as the free mixing of men and women – it provides a second-hand, but comprehensive, account of French and especially English political history and systems of government as he had learned about them from sources in India. He identifies as key factors the separation of Church and State, the rule of law and equality in the law, modern technological innovations, the end of the absolute power of the monarch, elections, and the principle of consultation involving both nobles and commoners. He also describes freemasonry, and gives it the name
faramushi (a play on the Persian word for forgetfulness). It is notable that his word for parliament,
edalat-khaneh or House of Justice, was used in the same sense during the Constitutional Revolution in Iran, and in its Arabic form by Baha’u’llah and Abdu’l-Baha to refer to the elected councils of laymen which they envisioned administering the affairs of Bahai communities. For Shushtari,
edalat would not imply a court of law: the term has the connotation of the fair distribution of recognition or resources among recipients, making it a good choice for the British Houses of Parliament, with Lords, clerics and commons all represented.
Mirza
Abu Talib Khan Isfahani’s
Masir Talibi fi balad Afranji reports his travels in 1798-1803, including a two-year residence in England and a shorter stay in France, and includes a detailed biography of Shushtari, with whom he was close (he was born in India in 1752; his father was from Isfahan). It was published in 1804 and 1812 (Calcutta).
Mirza Saleh Shirazi (b. circa 1798), one of the five students sent to England in 1815 by ‘Abbas Mirza, wrote admiringly of English society, which he called the ‘land of freedom.’
Then there are the progressive / modernist thinkers and writers in Persian, while those in Arabic are generally speaking ahead of the Persian in hearing and responding to European ideas. Afghani is one of these: Baha'u''ah refers to him and his writings in his Lawh-e Dunya:
"... It is reported that a certain person [1] went to the seat of the imperial throne in Persia and succeeded in winning the good graces of some of the nobility ... The aforesaid person hath written such things concerning this people in the Egyptian press and in the Beirut Encyclopedia that the well-informed and the learned were astonished. He proceeded then to Paris where he published a newspaper entitled Urvatu'l-Vuthqa [The Sure Handle] and sent copies thereof to all parts of the world. He also sent a copy to the Prison of 'Akká, and by so doing he meant to show affection and to make amends for his past actions."
Note that Baha'u'llah is reading the Egyptian press and an Encyclopaedia and a reformist newspaper published in Europe, and that he receives (and I know from other evidence) sends letters to leading reformist thinkers.
What is unique is not that he advocated democracy and popular representation -- which in his day were still unproven ideas, much discussed -- but that he made them religious principles. The world moves on, and one of the functions of the founders of religion is to adapt religion to the new circumstances. If there is no major reform, religion drifts out of contact with the current realities and becomes a strongly conservative force. But religion renewed can mobilise social forces for a new era. Early Christianity for example was not a conservative force, but rather a soft revolution.
