This article tells us about the history of self-advocacy in Denmark. It also gives some information about how services for people with learning difficulties in Denmark have changed over the past 100 years. In this article, I talk about "movements" of self-advocacy, which means the different types of self-advocacy groups that have grown in Denmark. I also describe how these movements have developed in "generations". Like families, I say that self-advocacy goes through "generations" where it has to change because the world around it is changing. Sometimes, self-advocacy groups have helped to make these big changes. I use theory in this article to help explain some of the very complicated developments that self-advocacy groups in Denmark have been through during their history.
