On 17 August 2017, three Hong Kong pro-democracy activists, Alex Chow, Nathan Law and Joshua Wong, were given prison sentences by the Court of Appeal for their roles in a protest at the Civic Square in front of the Central Government Complex in Tamar, Admiralty, on 26 and 27 September 2014. The events at the Civic Square helped set off massive pro-democracy protests, sometimes referred to as the Umbrella Movement, which lasted until police cleared the last of the protest sites in December 2014.
