The February 1917 Russian Revolution brought Lenin back to Russia. He had been living in Switzerland at the time and the revolution took him by surprise. The German High Command arranged for Lenin to be transported from Switzerland to Russia in a diplomatically sealed train. The Germans wanted Lenin to create more revolutionary disruption in the hope that a new Russian government would get Russia out of World War I.
If you mean during WW1, while the Provisional Government was in control of Russia, Lenin returned to Petrograd on the 16th April with the help of theGerman government (because the Germans figured that if the Bolsheviks were in power of Russia, they'd withdraw from the war and even if they failed to seize power, the turmoil in Russia could only help Germany's war aims).
It was a diplomatically-sealed train originating in Switzerland and bound for Russia, traversing Germany and Sweden. The Germans allowed the transit, not taking any chances that Lenin would disembark in Germany to spread his Communist propaganda, but fully welcoming the idea of him inciting revolt in Russia, which was at war with Germany. For this, Lenin's foes in Russia had denounced him as a "German spy". While he most likely was not anybody's spy, the revolution he eventually led certainly played into Germans' hands.
When the Russian Czar stepped down the new provisional government decided to continue Russia's part in WW1 by continuing to fight the Germans. Lenin and his small but powerful Communist Party promised to withdraw from the war as it was causing much destruction to Russia. Lenin had been living in exile from Russia and the Germans promised to get Lenin back into his country if he would end Russia's presence in WW1. The Germans were successful in sneaking Lenin back to Russia and this allowed the Germans to concentrate on the Western Front in France.

Russia was beaten badly by the Germans on the battlefield, while back in Russia, the Russian civilian people starved and went without. Also, Tsar Nicholas was a failure as a leader of Russia, just like French king Louis XVI was a failure. The Germans allowed Lenin (a Russian communist) to travel to Russia to get that nation out of the war, and Lenin led a revolution in Russia to try and solve the internal problems of Russia. The internal problems in Russia would not be solved for a long time.
Vladimir Lenin was the leader of Russia from 1917 to 1922. He was a communist, and he turned Russia into the Soviet Union. Lenin was predecessor to Stalin.
The Germans actively facilitated Lenin's return to Russia in order to further destabilize Russia and make it pull out of the war. The first revolution in February, 1917 had toppled the Tsar and his regime, but much to the chagrin of Germany the revolutionaries continued the war against Germany with full force. The Germans gambled (rightly, as it was to turn out) that for Lenin to establish Bolshevik power and defeat his Russian adversaries, he would need peace with Germany. When Russia indeed did sue for peace, the Germans could then - as had been their intention behind the whole Lenin strategy all along - concentrate all their military power on the Western front and try to force the deadlock that had been existing there for years. They failed at that, however.
Lenin became Russia's leader because Nicholas II was kicked off the throne by Lenin's followers.
The Germans knew perfectly well that Lenin was opposed to Russian involvement in WW I, and sure enough, the first thing the Bolsheviks did when they gained power was to pull Russia out of the war, which of course made things easier for their former enemy, Germany (and the Central Powers to which Germany belonged). Although Germany lost the war anyway.
