Epic Rap Battles of History (ERB) is a YouTube web series and music project created by Peter "Nice Peter" Shukoff and Lloyd "EpicLLOYD" Ahlquist. The series pits historical and pop culture figures against one another in a rap battle format. The characters portrayed are often determined by suggestions from viewers in the comments sections of the channel's videos. Shukoff and Ahlquist write each song themselves, researching the subject in order to find obscure details to use as references in the lyrics. As of March 26, 2021, the channel has 14.8 million subscribers and approximately 3.7 billion total video views. Following an extended hiatus, the channel returned with a bonus battle in December 2018, and the sixth season debuted on April 20, 2019 and a seventh is set to begin during 2021.
