Percederation

Andrea Salvini, Etruria's last centre-right president

Francesco Carcaterra, the leader of the right-wing Tribune Movement

Percederation is the general trend marking the decline of centre-right conservative political parties in Euclea since 2015. These parties, which traditionally have represented the right of Euclean politics, have seen a significant drop in support. Some parties have hit historic lows in support while others have disbanded entirely. The decline in support for traditional centre-right parties has been accompanied by an increase in support for centrist or nationalist, right wing populist parties. It is believed to be a contributing factor to the Pink Wave, a shift towards centre-left social democratic parties.

The name comes from the Vespasian per cedere, meaning yield. It originated after the collapse of the Etrurian Federalist Party in 2016, who were supplanted by the nationalist, right-wing Tribune Movement. Since then, it has been applied more broadly as centre-right parties throughout Euclea experienced decline. It has also been used to describe shifts within parties, away from centre-right politics towards right-wing politics.

In Eastern Euclea

Caldia

The Liberty Party began its decline in 2018, which culminated in its historic defeat in 2019. After forming the post government's in Caldia's post-war history, the party only won 18.4% of the vote and 89 seats. This was a major defeat for the party, which had never before fallen below 22.5%. The party's decline was largely attributed to the scandals of taoisigh Simi Ó Raghallaigh and Proin Casarnach. The party attempted a shift to the right under Pádraig Mac Piarais, but saw historic defeats in local elections under his leadership. For a time, the party fell into third place behind the National Party in opinion polls. It has lost support to the National Party and the liberal Caldish Democrats, matching the greater trend of percederation.

Gaullica

- Historical precedent with the downfall of 'Truth and Justice for a New Democracy' during the 1980s despite historical success, paving way for centre-right to be filled by 'Gaullican Conservatives'. - Splintering of the centre-right over economic and social liberals and traditional conservatives leads to the formation of the PRCP.

Elsewhere

Tengaria

Although Tengaria does not officially have political parties and is largely authoritarian, a similar effect has been cited by some scholars as being applicable under the same effect. During the presidency Dimitri Kovachev from 1983 to 2014, the "Pragmatist" faction of the Patriotic Union effective power over Tengaria. Although still largely conservative and right-wing, it promoted more moderate and centrist policies than those of Simeon Kovachev's presidency, including reforms which made Tengaria more in line with modern regimes. During this time as well, more centrist political groups promoting democratic reform were able to get some seats within the Senate, and the influence of the Patriotic Union was in decline. After Dimitri's death in 2014, his daughter Teodora Kovacheva took control of the Presidency, and began to bring the Union into more right-wing politics, bringing the "Purist" faction into power and increasing the use of right-wing rhetoric. Since then, the Patriotic Union has increasingly been pushing right-wing policies and regaining its political influence, which have lead some scholars to consider it to be undergoing Percederation.
