During the early twentieth century, a caste dispute known as the Eki-Beki dispute erupted among a group of historically related Konkani-speaking Brahman castes on the western coast of India. A faction among the castes argued that the variously related Konkani-speaking Brahman castes were originally one caste called the Gauda Saraswat Brahman (GSB) caste, which got split into several sub-castes. They further argued that the time had come to unite all these castes into one unified GSB caste. This faction came to be known as the Eki-faction, which meant the unity-faction. The Eki-faction was opposed by the majority of the members of the above-mentioned castes who disagreed with the idea of unification. This opposing faction came to be known as the Beki-faction, i.e. the disunity-faction. Despite the opposition from the majority, the Eki-faction managed to unite these different castes to form the contemporary unified GSB caste. The Gaud Saraswat Brahman caste in its current form is the product of this dispute. The formation of the GSB caste was initiated by members of these castes who had migrated from different rural regions of the western coast of India to the urban center Bombay. The rise of the GSB caste, however, became a contested process. Dominant non-GSB Brahman groups in Bombay discredited the migrants as being outsiders of lower ritual status. The unification movement was also opposed by the majority of these Konkani-speaking castes residing in the rural regions of the west coast of India. The struggle of the urban migrants for unification involved publication of Hindu texts and changes of normative practices, such as dining regulations and marriage arrangements, that affected the long-standing norms of maintaining ritual purity. Despite the opposition, the urban migrants partially succeeded in unifying the variously related Konkani-speaking Brahman castes. My dissertation is a history of this process.
