Mariela Muñoz became the first transsexual widely socially recognized as a mother in Argentina. She emerged as a leading figure during her struggle to recover legal custody of three of her children, which had been previously annulled by a judge. Moreover, in 1997 she became the first transsexual recognized as a woman by the state. This text analyzes the making of Mariela Muñoz's motherhood repertoires to redefine political, social, and intimate citizenship. It argues that her politics were paradoxical, in that she appealed to traditional meanings of womanhood such as fulfilment through motherhood and the duty of care for others. On the other hand, these uses of key cultural symbols displaced the imagined margins for travestis and transexuales and helped her enjoy popular support.
