During the afternoon of 21 October 2020, anti-government protesters marched from the Democracy Monument to Government House in the capital Bangkok. Upon reaching Government House the demonstrators delivered an ultimatum for Prime Minister Prayuth Chan-ocha to resign within three days and release arrested protesters, or they would resume disruptive protests. Prayuth did not immediately respond to the demands. Likely in an attempt to ease tensions, Prayuth later announced that the state of emergency in Bangkok which limits the number of attendees at public gatherings will expire at 1200 local time on 22 October.

In related developments, pro-monarchy demonstrators gathered in Bangkok, Lampang, Chiang Mai and other cities. At the Hua Mak campus of Ramkhamhaeng University in Bangkok minor altercations between anti-government and pro-monarchy demonstrators occurred briefly before police officers intervened to separate the two sides. There were no reports of violence at other rallies during the day.
