Viktor Andriyovych Yushchenko (Ukrainian: Віктор Андрійович Ющенко (help·info) Viktor Andrijovyč Juščenko) (born February 23, 1954) was the third President of Ukraine. He took office on January 23, 2005, following a period of popular unrest known as the Orange Revolution. He failed to secure a run-off spot during the 2010 Ukrainian Presidential Election. He has been praised for his democratic instincts
As an informal leader of the Ukrainian opposition coalition, he was one of the two main candidates in the October–November 2004 Ukrainian presidential election. Yushchenko won the election through a re-vote of the runoff between him and Viktor Yanukovych, the government-supported candidate. The Ukrainian Supreme Court called for the run-off election to be repeated because of widespread election fraud in favor of Viktor Yanukovych in the original voting. Yushchenko won in the revote (52% to 44%). Public protests prompted by the electoral fraud played a major role in that presidential election and led to Ukraine's Orange Revolution.
An assassination attempt was made on Yushchenko through dioxin poisoning in 2004 which left him severely disfigured.
