Naftoli Trop was born in Grodno, where he studied with his father, Rabbi Moshe Trop, who was rosh yeshiva of a local yeshiva. At 14, he left to learn in Kelm, where his study partner for ten years was Yerucham Levovitz, who went on to become mashgiach of the Mir yeshiva. Rabbi Trop proceeded to briefly study in Slabodka and Telz, where he became close to Eliezer Gordon. He learned for a short time in the Novardok yeshiva in Slonim, where he formed a close relationship with Yosef Yozel Horwitz. In 1889, when Yaakov Yitzchak Rabinowitz was appointed rosh yeshiva at Slabodka, Trop returned to Slabodka to study under Rabinowitz. At the age of twenty-one, Trop became engaged tothe daughter of Nosson Tzvi Finkel. However, she died a few months before the wedding. In 1895, Trop married Pesya Leah, the daughter of Eliezer Yaakov Chavas of Yanishok. Shortly after the wedding, he returned to Kelm where he joined a large group of young married scholars. He was greatly influenced by the mussar movement approach he chiefly absorbed in Kelm, but also in Slobodka and by means of his contact with Horowitz in Slonim. After four years of studying in Kelm, Trop was appointed rosh yeshiva of the Or HaChaim yeshiva in Slabodka, by its founder, Tzvi Levitan.
