Kremlin critic and Russian opposition politician Alexei Navalny has been convicted of misappropriating $500,000 worth of state-owned timber.
A court freed him from detention on July 19, pending an appeal of the court's ruling against him.
Navalny has been campaigning for the Moscow mayoralty -- officially registering as a candidate the day before his conviction -- and there have been allegations his trial has been politically-motivated.
Russian authorities insist that is not the case.
Who is Alexei Navalny?
Navalny is a corruption fighting lawyer who famously branded the ruling United Russia party -- founded by President Vladimir Putin -- "the party of crooks and thieves."
He has been a prominent organizer of street protests and has attacked corruption in Russian government, using his blog and social media.
In a 2011 article entitled "Russia rising: The Blogger Who Is Putin's Greatest Challenger," TIME magazine's Simon Shuster said before 2010 Navalny had been known "only to a fairly small online community."
But in November 2010, Shuster said, Navalny "blew the whistle" on what he said was a $4 billion embezzlement scheme at the state-run oil pipeline operator Transneft -- a claim vigorously denied by the head of the company and Russian president Vladimir Putin.
In January 2011, Transneft's boss branded the claims inaccurate, according to Reuters news agency. And in September that year, state-run news agency RIA Novosti quoted President Putin as saying no crimes had been committed by Transneft.
"The leaked documents he presented as evidence, which he posted on his blog, caused a sensation in the Russian and international press, and Navalny soon became known as Russia's top crusader against corruption," wrote TIME's Shuster.
In 2012, TIME included Navalny on its list of "The World's 100 Most Influential people."
Russian chess legend and opposition activist Garry Kasparov wrote the entry on Navalny -- then 35 -- saying he was -- "at the vanguard" of data dissidents.
How much of a threat does he pose to Putin/Kremlin?
CNN's Moscow correspondent Phil Black said Navalny's passion, charisma, fierce language and commitment to fighting corruption inspired many to join him in protesting on the streets.
Maria Lipman, a political analyst at the Carnegie Moscow Center think-tank, said during the 2011 and 2012 protests over alleged fraud in Russia's parliamentary and presidential elections Navalny was "by far the most popular figure."
"Navalny quite bravely took on some of the very influential people in Russia," she said.
Lipman said Navalny was a fearless and very talented public politician who had managed to "beat the system that Putin built" to keep outsiders out of the political framework.
Navalny presented "a serious political challenge as a result of his unique personality and his amazing energy," she said. "He was able, as a result, to build a following."
"He's become a popular figure but he cannot be described as the leader of the opposition," she said. "He is the most prominent civic figure."
