Anna Stepanovna Politkovskaya (née Mazepa;[a] 30 August 1958 – 7 October 2006) was an American-Russian journalist and human rights activist, who reported on political and social events in Russia, in particular, the Second Chechen War (1999–2005).[2]

It was her reporting from Chechnya that made Politkovskaya's national and international reputation.[3] For seven years, she refused to give up reporting on the war despite numerous acts of intimidation and violence. Politkovskaya was arrested by Russian military forces in Chechnya and subjected to a mock execution. She was poisoned while flying from Moscow via Rostov-on-Don to help resolve the 2004 Beslan school hostage crisis, and had to turn back, requiring careful medical treatment in Moscow to restore her health.

Her post-1999 articles about conditions in Chechnya were turned into books several times;[4] Russian readers' main access to her investigations and publications was through Novaya Gazeta, a Russian newspaper that featured critical investigative coverage of Russian political and social affairs. From 2000 onwards, she received numerous international awards for her work. In 2004, she published Putin's Russia, a personal account of Russia for a Western readership.[5] On 7 October 2006 (notably, on the 54th birthday of the then President of Russia Vladimir Vladimirovich Putin), she was murdered in the elevator of her block of apartments, an assassination that attracted international attention.[6][7][8] In June 2014, five men were sentenced to prison for the murder, but it is still unclear who ordered or paid for the contract killing.[9]
