context_page_description: Plaid Cymru is a social-democratic and democratic socialist political party in Wales advocating Welsh independence from the United Kingdom.
  Plaid was formed in 1925 and won its first seat in the UK Parliament in 1966. The party holds three of 40 Welsh seats in the UK Parliament, 10 of 60 seats in the Welsh Parliament, and 202 of 1,264 principal local authority councillors. It is a member of the European Free Alliance.
context_section_description: Gwynfor Evans's presidency coincided with the maturation of Plaid Cymru (as it now began to refer to itself) into a more recognisable political party. Its share of the vote increased from 0.7% in the 1951 general election to 3.1% in 1955 and 5.2% in 1959. In the 1959 election, the party contested a majority of Welsh seats for the first time. Proposals to flood the village of Capel Celyn in the Tryweryn valley in Gwynedd in 1957 to supply the city of Liverpool with water played a part in Plaid Cymru's growth. The fact that the parliamentary bill authorising the dam went through without support from any Welsh MPs showed that the MPs' votes in Westminster were not enough to prevent such bills from passing.
