This article examines three main areas in which historical analysis ma
kes a fundamental contribution to policy-making. Firstly, as specialis
ts of the past, historians contribute to the definition and protection
of a nation's collective memory, and, by the same token, question and
reinterpret it where historical fact or analysis constitutes the sour
ce of specific contemporary problems. Secondly, by contributing their
detailed knowledge of historical context, historians may deepen unders
tanding of current issues by placing them in their broader temporal co
ntext, thereby providing a basis for comparison with past situations w
hich may enlarge the range of policy options considered, as well as an
assessment of the real outcomes of past policy choices, and predictiv
e indications based on past experience of possible future issues of co
ncern. Finally, in tracing the processes of decisionmaking and the rol
e of individuals and institutions within the policy process itself, hi
storians raise awareness of the causes and consequences of current pol
icy choices, and in doing so contribute to a more rational approach to
policy-making. The discussion ends with a series of recommendations f
or improving co-operation between historical researchers and the polic
y-making community.
