The 2019–2020 Hong Kong protests, also known as the Anti-Extradition Law Amendment Bill (Anti-ELAB) protests, were a series of protests, strikes, and civil unrest in Hong Kong that began in June 2019. The protests were sparked by a proposed extradition bill that would have allowed for the extradition of criminal suspects from Hong Kong to mainland China. The bill was met with widespread opposition from citizens and human rights groups, who feared that it would be used to target political dissidents and undermine the autonomy of Hong Kong.

The protests quickly grew in size and scope, with large-scale marches and rallies taking place throughout the city. Many of the protests were peaceful, but some turned violent, with clashes between protesters and police. The police were criticized for their heavy-handed tactics, including the use of tear gas, rubber bullets, and water cannons.

The protesters demanded the withdrawal of the extradition bill, an independent inquiry into the police's handling of the protests, amnesty for arrested protesters, and universal suffrage in Hong Kong. They also adopted several other demands, such as "Five Demands, Not One Less" and "Liberate Hong Kong, revolution of our time".

The Hong Kong government, led by Chief Executive Carrie Lam, initially refused to withdraw the bill, but later suspended it in June 2019. However, the protests continued, with many protesters calling for Lam's resignation. Lam announced the formal withdrawal of the bill in September 2019, but the protests continued, with many protesters calling for her resignation and for an investigation into police brutality.

The protests continued throughout 2019 and 2020, with the police making a number of arrests and charging many protesters with various offenses. The COVID-19 pandemic led to a decrease in the size and frequency of the protests in 2020, but they continued to take place.

The Hong Kong government has been criticized by various countries, including the United States and the United Kingdom, for its handling of the protests and for its treatment of the protesters. The Chinese government has also been criticized for its role in the protests, with some countries accusing it of violating the autonomy of Hong Kong and violating human rights. The situation in Hong Kong is ongoing and continues to be a source of international concern and attention.
