The coordination of women's organizations, whether NGOs or NPOs, has been in operation for some time in Taiwan, notably among those in advocacy of certain policies at the national level. At the local level, however, women's organizations that establish horizontal integrative relations with one another are hard to come by. This paper targets the Panicle Women's Coalition in Kaohsiung as an exceptional case, investigating in some depth its bottom- up pattern of integration. It starts from the local women's NGOs, studying the informal coalition that spontaneously developed among them, the process of its emergence, and its interactive relations with the local government. In our research, we examine the horizontal linkages and integrative relations of these local women's NGOs, the background and conditions of the formation of the coalition, its role and functions of the coalition, its relations with the component organizations, its relations with the public sector, and the future of the coalition. It will be seen that the coalition did play an influential role in the earlier period for women's welfare. More recently, however, due to the limited nature of resources and its status as an NGO, the coalition has faced with certain uncertainties. Its role and status in the years ahead remain for further studies to investigate and ascertain.
