Missionary Day is observed in Mizoram, India, every January 11 to commemorate the arrival of the first European missionaries in 1894 and the subsequent Christianization of the region. The day marks the anniversary of Baptist missionaries James Herbert Lorrain and Frederick William Savidge, who arrived in Aizawl and began efforts to educate the Mizo people through Christian missions. They created a Mizo alphabet based on Roman script, established the first school, and translated key biblical texts. The missionaries' work laid the foundation for the spread of Christianity in Mizoram, where over 87% of the population now identifies as Christian. This public holiday reflects the significant impact of missionary activities on the local culture and society.
