BLMtwitter: The Black Lives Matter (BLM) Twitter Corpus

In May 2020, the murder of George Floyd led to protests throughout the United States and around the world. Along with these protests, social media platforms saw a dramatic increase in the volume of discussion regarding Black Lives Matter (BLM). Two years on, online discussion of BLM continues to be lively, not just in the United States but also internationally. This dataset represents one of the most extensive collections of Black Lives Matter tweets available, covering from 2010 through 2022 and including more than 50 million tweets overall. Parallel corpora for All Lives Matter and Blue Lives matter are also included. Monthly updates for 2023 are available on Github (https://github.com/amaurits/BLMtwitter), along with a datasheet and a preprint describing the dataset in more detail.
