Liu Xiaobo was a Chinese literary critic, human rights activist, philosopher and Nobel Peace Prize laureate who called for political reforms and was involved in campaigns to end Chinese Communist Party one-party rule in China. He was arrested numerous times, and was described as China's most prominent dissident and the country's most famous political prisoner. On 26 June 2017, he was granted medical parole after being diagnosed with liver cancer; he died a few weeks later on 13 July 2017.
Liu rose to fame in 1980s Chinese literary circles with his literary critiques. He eventually became a visiting scholar at several international universities. He returned to China to support the 1989 Tiananmen Square protests and was imprisoned for the first time from 1989 to 1991, again from 1995 to 1996 and yet again from 1996 to 1999 for his involvement on suspicion of inciting subversion of state power. He served as the President of the Independent Chinese PEN Center, from 2003 to 2007. He was also the president of Minzhu Zhongguo (Democratic China) magazine starting in the mid-1990s. On 8 December 2008, Liu was detained due to his participation with the Charter 08 manifesto.
