confederation

A confederation (also known as confederacy or league) is a union of political units for common action in relation to other units. Usually created by treaty but often later adopting a common constitution, confederations tend to be established for dealing with critical issues (such as defense, foreign affairs, or a common currency), with the central government being required to provide support for all members.

The 44th World Science Fiction Convention (Worldcon), also known as ConFederation, was held August 28 through September 1, 1986, at the Marriott Marquis and Atlanta Hilton in Atlanta, Georgia, USA. The convention was co-chaired by Penny Frierson and Ron Zukowski. Total attendance for the convention was reported as 5,811 members.
