Answer
Vazgen Manukyan spearheaded the mass rallies that followed the allegedly fraudulent presidential elections in 1996. The rallies were in protest of the election of Levon Ter-Petrosian as president, which was widely viewed as fraudulent. Manukyan was a prominent opposition leader at the time and was a strong critic of Ter-Petrosian. The rallies continued for several weeks and culminated in a massive demonstration in Yerevan on March 25, 1996.
