Russian President Vladimir Putin has stood -- often bare-chested -- at the helm of Russian politics since 1999, rotating between the presidency and the prime minister's office.
But before his fast rise to power, Putin spent most of his life far out of the limelight.
With Putin at the center of several global crises, from Syria to Ukraine, The WorldPost takes a look back at the leader's surprising past.
1. Vladimir Putin grew up in a communal apartment shared by three families in St. Petersburg (then known as Leningrad), and he says he remembers hunting rats in the stairwell.

4. Putin loves spy novels, once remarking “what amazed me most of all was how one man’s effort could achieve what whole armies could not.”
