Jordan was born around 1190 to a noble Saxon family. Educated at the University of Paris — the principal centre of Catholic scholastic learning of the early 13th century — he received the Master of Theology degree.
In Lent 1220, Jordan received the Dominican habit at the Dominican convent of Saint-Jacques in Paris — personally admitted to the Order by Bl. Reginald of Orléans (just before Reginald's death on February 1, 1220). Jordan rapidly rose in the Order: appointed Provincial of Lombardy in 1221, then — on the death of St. Dominic on August 6, 1221 — elected second Master of the Order of Preachers at the Bologna general chapter of 1222.
Jordan's fifteen-year mastership (1222–1237) consolidated the Dominican Order institutionally after the death of its founder. Under his governance, the Order expanded from approximately 20 to over 300 convents across Catholic Europe — producing the characteristic institutional geographical spread that would underpin the Dominican-scholastic-university tradition.
Jordan was famous for his vocation-recruitment preaching at the University of Paris — producing the famous burst of Paris student-Dominican vocations that became the stream of Dominican intellectual talent feeding the Paris-Dominican tradition (including Sts. Albert the Great, Thomas Aquinas, and dozens of other Paris-trained early Dominicans).
He composed the Libellus de Principiis Ordinis Praedicatorum (Little Book on the Origins of the Order of Preachers, c. 1233) — the first Latin biography of St. Dominic and the principal source for the Dominic-life narrative; and the famous Encyclica letters to the Order.
Jordan is most personally famous in the medieval Dominican tradition for his personal correspondence with Bl. Diana d'Andalò (1201–1236, the aristocratic Bolognese woman who became the foundress of the first Dominican women's-monastic convent of San Sisto at Bologna). The fifty surviving letters of Jordan to Diana (composed 1222–1236) constitute one of the principal medieval Catholic spiritual-friendship correspondences — analogous to the Bernard-of-Clairvaux / William-of-Saint-Thierry and Aelred-of-Rievaulx / Simon-Grammaticus spiritual-friendship traditions.
Returning from a Master's-visitation to the Dominican convents of Cyprus and the Holy Land, Jordan was shipwrecked in a storm off the coast of Syria on February 13, 1237. His body was recovered from the shipwreck and buried at the Dominican convent of Acre — the last Crusader-Kingdom capital.
