As Tamil Nadu moves closer to its next Assembly election, the familiar architecture of the state’s politics is again coming into view, with two broad alliances facing each other across a field shaped by Dravidian history, welfare politics and regional pride, with several smaller players trying to disturb the equilibrium. For decades the contest in the state has followed a rhythm unusual in Indian federal politics. Power alternated between the Dravida Munnetra Kazhagam and the All India Anna Dravida Munnetra Kazhagam, each leading wide alliances that gathered caste parties, ideological formations and local movements under their umbrella. Even when new actors emerged—from national parties to film stars—they were usually absorbed into this binary structure or they eventually dropped out of the race. The 2026 election is likely to retain that basic form, though the personalities and pressures around it have changed.
