Overview

This dataset contains structured data collected from public Telegram channels related to Iranian political news and information. It includes channel-level metadata and post-level content, with optional media references, collected for academic research purposes.

The dataset accompanies a research article currently under review and is released to support transparency, reproducibility, and further research on political communication and information diffusion on Telegram.
