This article studies two generations of the Mahmudabad family, which was one of the largest Muslim landholding families in India: Maharaja Sir Muhammad ‘Ali Muhammad Khan and Raja Muhammad Amir Ahmad Khan. The family were Twelver Shi‘as and hailed from Mahmudabad in Awadh. Specifically, it shows how intra-community links of marriage and kinship facilitated a flow of ideas, information and people and therefore created new networks. The article then explores these connections through the example of the Madrasa’t-ul Wa‘izeen, which was founded by the Maharaja and its two main publications, Al-Wa‘iz, an Urdu magazine and the English language The Muslim Review. The founding of the madrasa also demonstrates the importance of ideology, pilgrimage, preaching and their corresponding networks. These relationships are analysed keeping in mind local, national and transnational institutions and the role these played in creating ties between Mahmudabad, Lucknow and the wider Muslim world. This article thus presents a typology of a particular kind of Muslim transnationalism, showing how family, marriage, ideology and the importance of preaching mutually reinforced each other. The larger goal is to show how this family could be both ‘rooted’ in the local while also being part of the transnational Muslim community.
