Russian President Vladimir Putin has quickly become one of the most powerful and feared politicians in the world.

But he's had a long climb to the top — he spent years working in Russian intelligence and local politics before becoming the leader of the country.

And Putin could become even more relevant to the US in the coming years. President Donald Trump has often been criticized for cozying up to the leader of a country that is thought to work to undermine Western democracies.

Here's a look at how Putin rose to power and why some Americans fear him.

Putin's rise

Early life and KGB career

Putin was born to a working-class family in Leningrad in 1952. His father is a decorated war veteran and factory worker. An only child, Putin grew up in a Soviet Union-style communal apartment with two other families, as was typical at the time.

Growing up, Putin loved spy novels and TV shows. When he was still in school, he went to the KGB security and intelligence agency and asked how he could join, according to the journalist Ben Judah's book "Fragile Empire: How Russia Fell In and Out of Love with Vladimir Putin."

The people at KGB headquarters told him to work hard and study law. So Putin did exactly that, at Leningrad State University, and later spent 17 years as a mid-level agent working in foreign intelligence.

It was during this time that he had an experience that some experts have concluded to be a defining moment in his life.

In Dresden in 1989, an anticommunist mob formed outside KGB offices. Putin recounted that he was told the KGB couldn't do anything about it without orders from Moscow, and Moscow didn't say a word.

"The business of 'Moscow is silent' — I got the feeling that the country no longer existed," Putin later said, according to Judah's book. "That it had disappeared. It was clear that the Union was ailing. And that it had a terminal disease without a cure — a paralysis of power."

Judah wrote, "For Putin and his generation, those who did not come from intellectual families, who believed what they were told about the USSR's superpower success, and did not question propaganda, or want what they did not have — that moment was a defining scar."

As president, Putin is known for his nationalism and patriotism — traits that can be traced back to his youth. A profile of Putin that ran in The Washington Post in 2000 said he once refused to read a book by a Soviet defector because he didn't "read books by people who have betrayed the Motherland."
