An alliance between the Bahujan Samaj Party and the Samajwadi Party in the
electorally vital state of Uttar Pradesh during the 1998 Lok Sabha election
s would have prevented the BJP from coming to power at the centre. This art
icle uses coalition theory to explain why this alliance did not form. The a
nalysis reveals that coalition formation in the state is a logical strategy
given the fragmented nature of the party system. However alliances are com
plicated by social cleavages, factors internal to parties and the dynamic n
ature of electoral politics in the state. The article concludes with an ass
essment of prospects for future alliances in Uttar Pradesh and the applicab
ility of this case to coalition politics in India more generally.
