As soon as three months after the human-rights-based 1961 Turkish Constitution was ratified, Protestant missionaries began to migrate to the country and to missionize among Muslims. They evinced a similarity of calling and purpose, not merely due to their shared evangelistic faith, but also to their shared missiological influences. Most of them prepared for their work with assiduous acculturation, and they concentrated the fulfilment of their like-minded vision and mission upon five central activities: evangelism, discipleship, church planting, and Bible disseminating and teaching. These activities were initially consecutive, but then concurring, and they were carried out in a much greater number of specific, often creative ways. While many missionaries left or were forced to leave Turkey with a sense of having fallen short of their missional goals, considered together, the religious-freedom empowered, multi-diverse missionary force fulfilled a vital role in the sprouting of the Turkish Protestant movement.
