for political reasons. Until 1869, his name was even added to the list of traitors publicly cursed in Russian churches during the Feast of Orthodoxy service, along with Pugachev, Razin and False Dmitry I. Later, a positive view of Mazepa was taboo in the Soviet Union and considered as a sign of "Ukrainian bourgeois nationalism". During the years of Perestroika, however, many historical works saw light that viewed Mazepa differently. After Ukraine's independence in 1991, Mazepa was proclaimed a national hero in Ukraine's official historiography and mainstream media, as he was the first post-Pereyaslav Treaty hetman to take a stand against the Tsar, who failed to abide by the Treaty. This view however was disputed by pro-Russian factions. Russia has repeatedly condemned Ukraine for honoring the figure of Ivan Mazepa. According to an April 2009 survey by the Research & Branding Group, 30 percent of the population of Ukraine views Mazepa as "a man who fought for the independence of Ukraine", while 28 percent view him "as a turncoat who joined the enemy's ranks". During an event in Mazepyntsi to mark the 370th birthday (20 March 2009) of Hetman Mazepa, President Viktor Yushchenko called for the myth about the alleged treason of Mazepa to be dispelled. According to Yushchenko, the hetman wanted to create an independent Ukraine, and architecture thrived in Ukraine over the years of Mazepa's rule: "Ukraine was reviving as the country of European cultural traditions". The same day, around 100 people held a protest in Simferopol against the marking of the 370th birthday of Mazepa. In May 2009 the Russian foreign ministry stated in an answer to Ukraine's preparations to mark the 300th anniversary of the battle of Poltava and plans to erect a monument to Mazepa that those were attempts at an "artificial, far-fetched confrontation with Russia". Mazepa's portrait is found on the ₴10 (Ukrainian currency) bill. In August 2009, a monument to the hetman, the work of the sculptor Giennadij Jerszow, was unveiled at Dytynets Park in Chernihiv. The opening was accompanied by clashes between the police and opponents of the Mazepa. After researching his genealogy in 2009, Ukrainian President Viktor Yushchenko did not rule out that his family is connected with the family of Mazepa. In August 2009, Yushchenko decreed the resuming of a halted construction of an Ivan Mazepa monument in Poltava. A monument to Mazepa was to be erected on Slava Square
