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 their rival 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 (-1971)
The PDP has its origins in the Tsengian Socialist Union (TSU), a centre-left political party that existed from 1948 to 1965 and was the NPP's main rival. However, following the passing of Bill 643 in 1958, a law that criminalized communism and forced all the left-wing parties into the TSU, which inevitably led to infighting between the TSU's far-left faction, lead by Frederik Bao, and centre-left faction, led by Jack Lin.

Lin would eventually win the 1958 presidential election held later in the year, which caused increasing tension between Bao and Lin, culminating in the Longtan Coup on March 11, 1962, when Bao eventually disposed of Lin as president and started the Luanzheng Era, a period of civil disorder between the far-left and far-right in 1960s Tseng.

Modern era (1970-)
After the Luanzheng Era, many people were angry with the TSU for supporting the far-left domestic terrorists like Harold Kim and Zeng Xiao-long. However, there was a sizable minority of people that wanted an opposition force to the dominant NPP. Therefore, on February 6, 1971, the People's Democratic Party was founded. In the first legislative election year, 1972, the PDP achieved 42 seats in the National State Assembly.

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.

Policies
The PDP is described as centre-left, although many party members express a variety of different views ranging from the centre-right to the progressive left. Generally, the PDP is described as liberal and social democratic. The party supports moderate welfare policies involving women, minorities, indigenous people, senior citizens, and other disadvantaged groups of society.
