The Death of Nobel Prize Winner Liu Xiaobo

      China's Nobel Peace Prize winner and political prisoner, Liu Xiaobo, died Thursday. Liu was first imprisoned following the pro-democracy protests in Beijing's Tiananmen Square. Following those protests, the Chinese government killed untold numbers of individuals and imprisoned hundreds for crimes linked to the demonstrations.

       Despite that initial imprisonment, Liu continued to advocate for human rights, freedom of expression, and an independent judiciary. He was imprisoned three more times and spent his final days in a hospital after being diagnosed with advanced liver cancer.

       Liu is only the second winner of the Noble Peace Prize to die while being held in prison. The first was Carl von Ossietzky, who died in a German prison in 1938 while serving a sentence for opposing  Hitler's Nazi regime.
