This paper revisits the political history of the Roman Republic in the third decade of the first century b.c. Its central contention is that the dominant feature of the period was neither a reshuffle of alliances within the ‘Sullan’ senatorial nobility nor the swift demise of Sulla's legacy. Attention should be focused instead on some crucial policy issues which attracted debate and controversy in that period: the powers of the tribunes, the corn supply of Rome, the rôle of the Senate, the revival of the census, and the full inclusion of the Allies into the citizen body. The political strategy of M. Aemilius Lepidus (cos. 78 b.c.) and its medium-term repercussions also deserve close scrutiny in this connection.
