The human rights of people living with disabilities has a chequered past. Up until the 1970s, disability was seen as something to be ‘treated’, and so it was most often viewed through the Medical Model and not the Social Model we use today. In fact, the human rights of people with disabilities were not officially recognized internationally until 1971, with the proclamation of the UN Convention on the Rights of Mentally Retarded Persons; and it was only in 1975 with the proclamation of the UN Convention on the Rights of Disabled Persons that the social, political, civic and human rights of people with disabilities were officially recognized internationally.
As can be seen in the timeline - see here, since 1975 global communities have been inching ever closer to creating a parity of esteem for people living with disabilities.
The first International Day of People with Disability was held on 3rd December 1992. Since then, the day has been an occasion of celebration and reflection throughout the world.
