Deciphering Secrets: Unlocking the Manuscripts of Medieval Spain is the Massive Open Online Course(MOOC) and crowdsourcing initiative of the Revealing Cooperation and Conflict ProjectRCCP is a scholarly initiative that re-examines historical cases of medieval and early modern Jewish, Christian, and Muslim interaction as well as an activist endeavor intent on buttressing humanistic reflection within academia as well as the general public.

The Deciphering Secrets website is both an educational platform and a crowdsourcing effort relating to the Spanish Late Middle Ages (1200-1500 c.e.) and Early Modern Era (1500-1700 c.e.).

Deciphering Secrets began as a summer 2014 Massive Open Online Course (MOOC) taught by Dr. Roger L. Martinez-Davila (University of Colorado, USA) on This course attracted 10,000+ students from 140 nations and over 2,500 students completed it. Almost 1,000 former students elected to continue work as “citizen scholars”. This website extends the core curriculum of the course — “Students will explore the history of Jews, Christians, and Muslims in late medieval, fifteenth century Spain. Serving as citizen-scholars, students will learn about the positive and negative elements of inter-religious co-existence in Plasencia, Spain, and more importantly, contribute to an international scholarly effort by helping transcribe manuscripts.”
