The International Disability Alliance (IDA) was established in 1999 as a network of global and, since 2007, regional organisations of persons with disabilities (DPOs) and their families. IDA was instrumental in establishing the International Disability Caucus (IDC), the network of global, regional and national organisations of persons with disabilities and allied non-governmental organisations (NGOs), which was to become a key player in the negotiation of the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD).
