People's Democratic Party (Tseng Republic)

The People's Democratic Party (Chinese: 人民民主黨; 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.

Early years (1939-1958)
The PDP was founded on February 6, 1939 by mergers of many left-wing Tseng nationalist parties in Japanese Tseng. It worked with the NPP to push the Japanese out of Tseng.

In 1946, after the independence of Tseng, the parties disbanded, and the PDP became a minor party. In 1953, the PDP and the more powerful Socialist Party merged, and the PDP gradually gained popularity. 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.
