The “Ayo Mondok” Movement is part of the pesantren's response to modernity. In the modern era like this, there are still many Muslim societies in Indonesia that make pesantren a reference for formal and informal educational institutions. Indeed, initially the pesantren was only traditional and only aimed to explore the science of religion. However, along with the modernization of the times, Islamic boarding schools have not only become institutions to explore religious sciences but also general science. This paper explains the history and development of pesantren, and how the system of pesantren education answers the challenges of modernity. To get the desired results, the research library was chosen by researchers as the research method in this study. The results of this study reveal that Islamic boarding schools are a gathering place for santri to get religious knowledge from a cleric. The beginning of the pesantren was only a simple hut which was built as a makeshift with the aim of getting closer to the kyai or the teacher intended for the purposes of studying religion. While the system of pesantren education is still using the book of salaf or more familiarly called kitab kuning.
