The Hong Kong 1 July protests was an annual protest rally originally held by the Civil Human Rights Front from the day of handover in 1997 on the HKSAR establishment day. However, it was not until 2003 that the march drew large public attention by opposing the legislation of Basic Law Article 23. The 2003 protest, with 500,000 marchers, was the second-largest protest seen in Hong Kong since the 1997 handover.

The Civil Human Rights Front (CHRF) was an organisation that focused on the issues of Hong Kong politics and livelihood, affiliated with almost all pan-democratic camps in Hong Kong. It was founded on 13 September 2002 and disbanded on 15 August 2021.
