People with intellectual disabilities have been treated poorly throughout history. As an abused, discriminated and labeled group, they lived on the margins of society, without the possibility of enjoying their human and civil rights. With the emergence of the social model and the concept of normalization, the view of people with intellectual disabilities becomes more humane. They are no longer seen as less valuable, and society begins to believe that people with intellectual disabilities can become the main and active actors in making decisions important to their lives. As one of the most vulnerable groups, they are still trying to take their equal place in society. They do this in various ways, including through the self-advocacy movement, where they speak on their own behalf. In standing up for their rights, they need support, which can be provided through formal and informal sources. The Convention on the Rights of Persons with Disabilities, as one of the most important documents for people with disabilities, emphasizes the importance of providing support to people with intellectual disabilities to allow them full participation in the community and a fulfilled life. By providing proper support, listening to their needs, putting people with intellectual disabilities at the center of decision-making, and providing accessible and easy-to-understand information as well as community awareness, people with intellectual disabilities can move away from the margins of society and become equal members of the community who enjoy the same rights as other citizens and achieve independence and a better quality of life.
