The ADR has its roots in a demonstration in Luxembourg City on 28 March 1987, held to protest at the disparities between the 5/6ths final salary scheme enjoyed by civil servants and the basic state pension received by everyone else. The large crowd, and the collection of 10,000 signatures for a petition demanding change, persuaded the organisers that there was widespread public support. The party was founded on 12 May 1987 as the 'Action Committee 5/6ths Pensions for Everyone' ("Aktiounskomitee 5/6 Pensioun fir jiddfereen").
