# Political Parliamentary Corpus (PPC)

A multilingual corpus of **parliamentary speech**, **party manifestos** and (for German) **historical newspapers**, exposed with one **config per language**. Every record follows a single unified schema, so the languages are directly comparable.

- **44,978,179** documents (~**16.5B** tokens, chars/4 estimate)
- **5** languages: `de`, `en`, `it`, `pl`, `tr`
- Coverage **1803–2026**
- 22 sources, unified schema
