Answer:
The activities of Sufi missionaries
Step-by-step explanation:
The activities of Sufi missionaries were evident in the continued spread of Islam across Afro-Eurasia in the period 1200-1450 as Sufis get to have new converts in areas including Anatolia, Central Asia, India, and Southeast Asia in general.
Following the disintegration of the Abbasid Caliphate, the Sufi missionaries took it upon themselves to spread the religion of Islam, by preaching Islam as the religion of peace. These Islamic missionaries are often referred to as Dakwah and it is a means of converting non-Muslims to Islam in a non-violent way.
