The transformation of comparative politics in the postwar period began
with concerns about the scope and method of the field: what it covers
and how theory may be constructed in it. This article reconsiders the
issue of scope. It argues, first, that comparative politics should be
regarded simply as the study of macropolitics, or politics at the sys
tem level, and that it thus comprises all political systems, past, pre
sent, and future. It discusses, second, the need for greater historica
l depth in the field and, third, the need for greater social width, pa
rticularly through the study of power, pressure, and authority in all
aspects of society.
