The Giani qualification is formally conferred by traditional Sikh educational institutions dedicated to scriptural study, most prominently the Damdami Taksal, a seminary tracing its own founding to the tenth Guru's court and long associated with rigorous training in scriptural exposition, correct recitation and traditional exegesis, alongside other gianis trained more informally under individual scholars, so the title spans both a formal institutional qualification and a looser recognition of learning depending on how and where it was earned.
The Damdami Taksal became a name known well beyond Sikh religious circles in the twentieth century when Jarnail Singh Bhindranwale, one of its later heads, became a central and highly controversial figure in Sikh political life in Punjab during the late 1970s and early 1980s, a period that ended with the Indian army's 1984 assault on the Golden Temple complex, Operation Blue Star, and Bhindranwale's death in it, an episode that remains a deeply contested and painful part of recent Sikh history quite separate from the ordinary scriptural and teaching work the Giani title otherwise denotes and that most gianis, before and since, have had nothing to do with.
