The roots of Pondok Modern Darussalam Gontor reach back to the eighteenth century, when a religious teacher named Kyai Ageng Hasan Besari established Pondok Tegalsari in a village ten kilometers south of Ponorogo, East Java. Thousands of santris -- students of the pesantren tradition -- traveled from across the archipelago to study there, and the school's leadership passed through six generations. But by the mid-nineteenth century, Pondok Tegalsari was declining. A gifted student named R.M. Sulaiman Djamaluddin, a descendant of the royal family of Cirebon's Keraton Kasepuhan, married the headmaster's youngest daughter, and together they were tasked with starting fresh. They moved three kilometers east to a place called Gontor. The area was still thick forest, a known hideout for robbers and criminals. Sulaiman and his wife Oemijatin brought forty students with them and built what became Pondok Gontor Lama -- the Old Pondok. When the third-generation leader, Kyai Santoso Anom Besari, died young in 1918, he left seven children and a school without direction.

Three of those seven children refused to let the school die. After studying at traditional pesantrens and modern institutions across Java, Ahmad Sahal, Zainudin Fananie, and Imam Zarkasyi returned to Gontor on September 20, 1926 -- the date of the Prophet Muhammad's birth commemoration -- and pledged to reestablish the school as something new. They called it Pondok Modern Darussalam Gontor, and the word "modern" was deliberate. The Trimurti fused traditional Islamic education with contemporary pedagogy, making Arabic and English mandatory languages on campus. Students were forbidden from speaking Javanese or Indonesian during designated hours; discipline was enforced through peer accountability rather than punishment. By 1936, ten years after the refounding, they had established the Kulliyatul Mu'allimin Al-Islamiyyah, an Islamic Teachers College with a four-to-six-year curriculum. The pesantren was producing not just scholars of religion but teachers who could carry its methods outward.

The list of Gontor alumni reads like a directory of Indonesian public life. Idham Chalid, declared a National Hero of Indonesia, served as the second chairman of Nahdlatul Ulama, the country's largest Islamic organization. Hasyim Muzadi became its fourth chairman. Din Syamsuddin led Muhammadiyah, the second-largest. Hidayat Nur Wahid served as speaker of the People's Consultative Assembly. Lukman Hakim Saifuddin became Minister of Religious Affairs. Nurcholish Madjid, often called Indonesia's most important Islamic intellectual of the late twentieth century, was a Gontor graduate. So was the poet Emha Ainun Nadjib, and the novelist Ahmad Fuadi, whose bestselling book The Land of 5 Towers is a fictionalized account of his years at the school. Hasanain Juaini, an environmentalist, won the Ramon Magsaysay Award. The school's principle that "education is more important than teaching" produced people who did not merely know things but acted on them.

Today, the pesantren is governed by a fifteen-member Waqf Board elected every five years from among alumni. The executive leadership, also chosen by the board, currently rests with Hasan Abdullah Sahal, who has served since 1985, alongside Amal Fathullah Zarkasyi and Akrim Mariyat, appointed in 2020. The campus has expanded far beyond its East Java origins. The women's division, Kulliyatul Mu'allimat Al-Islamiyyah, was established in Mantingan, Ngawi Regency -- a hundred kilometers from the main campus. The University of Darussalam, founded by the Trimurti in 1963, now offers programs spanning Islamic philosophy and Qur'anic studies to pharmacy, informatics engineering, and agrotechnology. All university students live in campus dormitories under the guidance of the rector, maintaining the boarding tradition that has defined Gontor since forty students followed their teacher into the forest. The motto remains pointed: no partying, simplicity, education for the community, and the pursuit of knowledge as devotion. A century after three brothers pledged to rebuild what their father left behind, the school they gave away keeps growing.
