The 1970s marked a turning point in disability advocacy and public policy in Washington State. During this decade, people with intellectual and developmental disabilities, families, and advocates increasingly challenged institutional care, exclusion from schools and communities, and the lack of individual rights. National civil rights movements, federal legislation, and growing public awareness helped push disability issues into broader conversations about equity and access. In Washington, these shifts led to early reforms in education, services, and oversight, and laid the foundation for more organized advocacy and systems change. The developments of the 1970s directly shaped the conditions that led to the creation of the Washington State Developmental Disabilities Council in 1976 and set the direction for decades of progress that followed.
