1960s

Support for the party declined slightly in the early 1960s, particularly as support for the Liberal Party began to stabilise from its long-term decline. In 1962, Saunders Lewis gave a radio talk entitled '' Tynged yr Iaith'' (The fate of the language) in which he predicted the extinction of the Welsh language unless action was taken. This led to the formation of

in which the party achieved massive swings of 30% and 40% respectively, coming within a whisker of victory. The results were caused partly by an anti-Labour backlash. Expectations in coal mining communities that the Wilson government would halt the long-term decline in their industry had been dashed by a significant downward revision of coal production estimates. However, particularly in Carmarthen, Plaid also successfully depicted Labour's policies as a threat to the viability of small Welsh communities.


1970s

In the 1970 general election, Plaid Cymru contested every seat in Wales for the first time and its vote share surged from 4.5% in 1966 to 11.5%.

A curiosity that will give birth – sooner than many think – to an independent Wales." He went on to say, "For Wales to be free, we must first be united. And, that is what this Co-operation Agreement sets out to achieve. It launches us on a pathway to a united Wales, one that, sooner than we perhaps think, will find it both comfortable and natural, indeed essential, to join the world community of normal, independent nations." The co-operation agreement was ratified by Plaid's conference, with 94% voting in favour. "This is a huge step forward for Wales and our democracy," Price said. "The co-operation agreement will bring immediate, tangible and long-term benefit for the people of Wales. All primary school children will now receive free school meals; there will be free childcare for all two-year-olds; and radical action to tackle the housing crisis. There will be stability payments to support family farms; exploration of an accelerated pathway to net zero by 2035; the creation of Ynni Cymru – a company to expand community-owned renewable energy generation; and a new and reformed Senedd – bigger, more diverse, and gender balanced in law. From feeding our children to caring for our elderly, this is a nation-building Programme for Government which will change the lives of thousands of people the length and breadth of our country for the better. And none of it would be happening without Plaid Cymru."

*The 2012 figures exclude Anglesey, where the vote was delayed until 2013. The changes in seats and votes shown for 2012 are a direct comparison since the 2008 elections in the 21 councils up for election (i.e. excluding Anglesey). In 2008, Plaid won 205 seats including six in Anglesey. For the purposes of this table the 205 figure has been reduced to 199 for the 2012 elections where the party lost 41 of the 199 seats it was defending on the night, leaving them with 158 seats. In the 2013 elections in Anglesey, the party won 12 seats, up from the 6 it won in 2008 (although there were significant boundary changes and a reduction in the total number of seats from 40 to 30). The 2017 figures are based on changes from the 2012 and 2013 elections. ''(Hence the slight discrepancy in the percentage increase.)''
