The Fiftieth Anniversary of the revelation by 'Abdu'l-Bahá, in March and April 1916, of the first Tablets of the Divine Plan, has witnessed the conclusion of a feat of pioneering unparalleled in the annals of the Cause. A year ago the call was raised for four-hundred-and-sixty-one pioneers to leave their homes within twelve months and scatter throughout the planet to broaden and strengthen the foundations of the world community of Bahá'u'lláh. There is every hope that with the exception of thirty-four posts whose settlement is dependent upon favourable circumstances all the pioneer goals will be filled by Ridvan or their settlement will be assured by firm commitments. The gratitude and admiration of the entire Bahá'í world go out to this noble band of dedicated believers who have so gloriously responded to the call. These pioneers, who have arisen for the specified goals, have been reinforced by a further forty-five believers who have settled in the goal territories, while sixty-nine more have left their homes to reside in twenty-six other countries already opened to the Faith. All told, in the course of the year, five-hundred-and-five Bahá'ís have arisen to pioneer beyond their homelands, the largest number ever to do so in any one year in the entire history of the Cause.
