The modern missionary movement refers to the period of Christian missions that began in the late 18th century and continued through the 19th and 20th centuries. It was characterized by an increased focus on evangelism and social reform, and a growing awareness of the need to share the Christian message with people around the world.

The modern missionary movement was influenced by a number of factors, including the growth of colonialism and imperialism, the development of new technologies like steamships and printing presses, and the rise of religious revivalism in Europe and America. Missionaries during this period often came from the United States and Europe, and they traveled to countries in Asia, Africa, and the Pacific Islands to spread the gospel message.

One of the key features of the modern missionary movement was a growing emphasis on social reform and humanitarian aid. Many missionaries believed that it was not enough to simply preach the gospel; they also had a responsibility to address the social and economic problems facing the people they served. This led to the establishment of schools, hospitals, and other social institutions, as well as efforts to promote literacy and economic development.

Another important feature of the modern missionary movement was the development of new methods and strategies for evangelism. Missionaries used a variety of techniques to share the gospel, including preaching, one-on-one conversations, literature distribution, and the use of media like radio and television.

The modern missionary movement had a profound impact on the spread of Christianity around the world, and it continues to shape the work of Christian missions today. Many of the institutions and organizations that were established during this period are still active today, and the principles and practices developed during the modern missionary movement continue to guide the work of Christian missions around the world.
