The Office of Intergovernmental Affairs (IGA) was established in the Executive Department in 1971 to act as the City's liaison with other cities and governmental agencies. In 1973, the IGA was moved to the Office of Executive Policy, and in 1975 was incorporated into the Office of Policy Planning. The Office of Intergovernmental Relations (OIR) became an independent agency in 1979, and absorbed the former Office of International Affairs in 1992. OIR represents and promotes the interests of the City of Seattle with federal, state, regional, local, tribal and international governments. OIR is the City's lobbyist during the State's legislative sessions.
