May 29. On this date in 1926, Shoghi Effendi referred to the publicity generated by remarks made earlier by Queen Marie of Romania as "this most astonishing and highly significant event in the progress of the Cause". "In was at this time, when affliction was literally engulfing the Guardian, that, on 4 May, the Toronto Daily Star published a highly appreciative statement made by Queen Marie of Rumania on the Bahá'í Faith, a statement, followed by others during the course of her visit to the United States and Canada, which was printed in about two hundred newspapers and constituted some of the widest and most spectacular publicity the Faith has ever received."

From Chapter 4 of Amatu'l-Bahá Rúhíyyih Khánum's book The Priceless Pearl, titled "Martha Root and Queen Marie of Rumania"...

Shoghi Effendi used to remark that out of his sufferings something always seemed to be born. He would go through these ordeals by fire - for indeed he seemed to fairly burn with suffering - and then some rain from heaven, in the form of good news, would shower upon him and help to revive him. I am afraid the mystery of sacrifice still remains a mystery to me, but certainly the Holy Ones of this world buy their victories dearly.
In was at this time, when affliction was literally engulfing the Guardian, that, on 4 May, the Toronto Daily Star published a highly appreciative statement made by Queen Marie of Rumania on the Bahá'í Faith, a statement, followed by others during the course of her visit to the United States and Canada, which was printed in about two hundred newspapers and constituted some of the widest and most spectacular publicity the Faith has ever received. In a confidential letter written on 29 May the Guardian refers to this as "this most astonishing and highly significant event in the progress of the Cause".

In 1930 her Majesty visited Egypt with her daughter Ileana. Shoghi Effendi, having had the unfortunate experience of indiscreet publicity during her visit to Cyprus, wired Alexandria on 19 February: "Advise Assembly in case Queen visits Egypt convey only written expression of welcome and appreciation on behalf Bahá'ís. Letter should be briefly carefully worded. No objection sending flowers. Individual communications should be strictly avoided. Inform Cairo."
In the hope that at last the Queen would be able to visit the Bahá'í Holy Places in Palestine the Guardian had had Bahá'u'lláh's Tablet to her grandmother, Queen Victoria, copied in fine Persian calligraphy, and illuminated in Tehran. On 21 February he cabled Tehran: "Illuminated Tablet Queen Victoria should reach Haifa not later than March tenth on one or several pages." This was to be his gift to Her Majesty. Hearing no news of the Queen's plans once she had reached Egypt he wired to her direct on 8 March: "Her Majesty, the Dowager Queen Marie of Rumania, abroad Mayflower, Aswan. Family of 'Abdu'l-Bahá join me in renewing the expression of our loving and heartfelt invitation to your gracious Majesty and Her Royal Highness Princess Ileana to visit His home in Haifa. Your Majesty's acceptance to visit Bahá'u'lláh's Shrine and prison-city of 'Akka will apart from its historic significance be a source of immeasurable strength joy and hope to the silent sufferers of the Faith throughout the East. Our fondest love, prayers and best wishes for Your Majesty's happiness and welfare."
Receiving no reply to this communication Shoghi Effendi sent another wire on 26 March to the Queen at the Hotel Semiramis in Cairo: "Fearing my former letter and telegram in which Family of 'Abdu'l-Bahá joined me in extending invitation to Your Majesty and Her Royal Highness Princess Ileana may have miscarried, we are pleased to express anew the pleasure it would give us all should Your Majesty find it feasible to visit Bahá'u'lláh's and 'Abdu'l-Bahá's Shrines and the prison-city of 'Akka. Deeply regret unauthorized publicity given by the Press." Two days later the Rumanian Minister in Cairo wired Shoghi Effendi: "Her Majesty regrets that not passing through Palestine she will not be able to visit you."

Although Bahá'ís frequently refer to Queen Marie of Romania as "the first member of a royal family to embrace the Bahá’í Faith," Queen Marie's daughter, Princess Ileana of Romania, disputes this claim:

"It is perfectly true that my mother, Queen Marie, did receive Miss Martha Root several times.....She came at the moment when we were undergoing very great family and national stress. At such a moment it was natural that we were receptive to any kind of spiritual message, but it is quite incorrect to say that my mother or any of us at any time contemplated becoming a member of the Baha’i faith."

While the Administrative Order publicly eschews involvement in partisan politics, it has no reservations about routinely using its media outlets to proudly tout unelected royal leaders who are Bahá'í.

For example, on February 19, 1968, Malietoa Tanumafili II, one of Samoa's four paramount chiefs, became a Bahá'í.

Also, On April 24, 2017, the Bahá'í World News Service published a story about Djaouga Abdoulaye, who "became a Baha’i in the 1980s when the Faith initially came to Benin." The news report states that he was enthroned High Chief in July of 2016, assuming a "position of moral and customary authority for the approximately 100,000 Fulani living in the area."

While rare and not promoted in the media outlets of the Administrative Order, there have been Bahá'ís who have been elected to office, such as Ted Livingston, who was the first Bahá’í in the United States to be the mayor of a city when he was elected Mayor of Cottonwood Falls, Kansas
