Historically, the two most important instances of violent protest by nationalists were the burning of the Penyberth Royal Air Force Bombing School in 1936, which resulted in the jailing of three leading Plaid members, and the attempts to halt the flooding of the Tryweryn Valley to construct a reservoir in the early 1960s. In regard to the latter case, the party's general secretary said that if ‘violent action… is undertaken in an attempt to force the Government to respect the wishes of the people of Wales, it has ample justification’ (quoted in Butt-Philip, , The Welsh Question, p. 94).Google Scholar

⁸ Due to the influence of one of the Plaid's early leaders, Saunders Lewis, the aim of political autonomy has traditionally taken a secondary role to cultural freedom. In a highly influential statement, Lewis, (Principles of Nationalism (Cardiff: Plaid Cymru, 1975, first edition 1926), p. 5)Google Scholar argued that nationalists should aim for ‘self-government. Not independence. Not even unconditional freedom. But just as much freedom as may be necessary to establish and safeguard civilisation in Wales’.

There are well-known reservations about using regression when the dependent variable is dichotomous (as is the case here with support for Plaid Cymru). However, these difficulties are of no practical consequence unless the marginals are highly skewed and there is a small sample size (Kmenta, , Elements of Econometrics, pp. 425–7)Google Scholar. Moreover, recent research has suggested that the log-linear alternatives to regression are considerably less robust.

¹⁷ There is, of course, a six-year gap between the Welsh survey and the remaining surveys used in the table, so that comparisons are subject to the normal qualification that some differences may be caused by period effects.

¹⁸ Inglehart, (‘Postmaterialism in an Environment of Insecurity’)Google Scholar argues that there has, in fact, been only modest changes in the value priorities of Western mass publics during the 1970s.

¹⁹ A factor analysis of these items produced loadings similar to, but not exactly the same as, Inglehart's factor analysis (The Silent Revolution, Table 2.4).

²⁰ The scale was constructed in the following way, exactly in accordance with Inglehart, 's scale (The Silent Revolution, p. 52, footnote 22)Google Scholar. Each respondent was given a score of +2 if both his first and second choices overall were post-materialist and +1 if only one item was post-materialist. Another point was added if the lowest priority overall was materialist; another point was added for each pair of two post-materialist items; another point was added for each pair of two post-materialist items chosen in the first three sets; and one point was deducted for each pair of materialist items chosen among the three sets. Negative scores were coded as zero, and scores of five and six made into five. Scoring the scale on a zero to one metric has the advantage that a metric partial regression coefficient, when multiplied by 100, can be interpreted as a percentage change. For example, a regression equation that produces a metric partial regression coefficient by 0·10 for sex when regressed against, say, Labour partisanship, implies that a male is 10 per cent more likely to vote Labour than a female.

²³ There are three reasons why we might expect post-materialists to have a greater protest potential. Firstly, their better education and higher occupational status make post-materialists more materially secure, consequently leaving them more time and energy to devote to other concerns. Secondly, these very concerns will have a greater likelihood of generating dissatisfaction with the established political order since post-materialists are, by definition, more likely to challenge the prevailing materialist ethos. Thirdly, the threat of violent protest is likely to be less repugnant to post-materialists since it threatens things they value less than do other citizens.

²⁶ During the 1970s, Welsh language activists damaged television transmitters and disrupted broadcasts in support of a Welsh language television channel. The leader of Plaid Cymru, Gwynfor Evans, also threatened to start a hunger strike on the issue in 1979.

²⁷ Two items, support for rent strikes and the holding of legal meetings, loaded on both factors and were therefore excluded from the final factor analysis.

²⁸ The scales were constructed by scoring the missing values for each component item to the mean, dividing each by its standard deviation, and then summing them. The resulting scale was then converted onto a zero to one metric, for the reasons given in footnote 20.
