People's Democratic Party (Tseng Republic)

The People's Democratic Party (Chinese: 人民民主黨; Rénmín Mínzhǔ Dǎng; PDP) is a centre-left party and one of two major political parties in contemporary Tseng, the other is the National Prosperity Party (NPP). It is the current ruling party of Tseng since 2016, breaking 36 years of NPP rule.

The PDP is socially liberal, seen as strong advocates of human rights (including support for same-sex marriage), environmental protection, and affordable college tuition.

The PDP's Chinese name is often abbreviated to 人民黨, or Renmindang.

Early years (1939-1958)
The PDP was founded on February 6, 1948 by mergers of many left-wing Tseng nationalist parties, including the powerful Socialist Party.

In the 1958 election, the PDP grabbed its first victory.

Internal conflict (1958-1970)
Conflict between the progressives and the moderates in the PDP arose after the NPP declared all far-left parties outlawed a few days before the 1958 election. On March 11, 1962, socialists and progressives attacked and disposed of Jack Lin, the president, who they felt, was "too far-right" (Lin was a centre-leftist), and replaced Lin with Frederik Bao, a socialist and Maoist.

Modern era (1970-)
After the Luanzheng Era, many people were angry with the PDP for supporting the far-left domestic terrorists like Harold Kim and Zeng Xiao-long. As a result, the number of seats they had in the National State Assembly (NSA) decreased, but they somehow made a big return in 1972, with 42 seats won. The next election year, 1976, the PDP had a majority.

In 1976, Guo Ming-wang was elected. Guo would be the last PDP president to lead Tseng until 2016, when John Cheng was elected.

After 1980, the PDP only held 2 seats in the NSA, before being locked out from 1988 to 2000.

John Cheng became the first PDP president ever to win a second term in 2020.
