This article considers the decline of Scottish Conservatism, 1951-97. The s
tatistical data indicate that 91 percent of the variance in Tory support is
accounted for by an underlying negative trend against time, that similar p
atterns appear when the data is disaggregated by region, and that short-ter
m fluctuations have been more in conformity with English results than is co
nventionally understood. The process of generational change is seen as a wa
ning of the cultural conditions which produced the centre-right coalition t
hat dominated Scottish politics, 1931-64, and its fragmentation into Conser
vatism, Liberalism, and Scottish Nationalism. The changed circumstances are
not seen as peculiarly Scottish, but the consequences for Scottish Conserv
atism of an evolution affecting the centre-right across the United Kingdom.
