The opposition says it has three main demands – the “immediate withdrawal” of troops from Ukraine, the trial of Putin as a “war criminal” and the liberation of all political prisoners in Russia.
The Russian war on Ukraine was a major focus of the protest, which finished at the Russian embassy in Berlin.
Navalnaya echoed the words of her late husband, who urged supporters to “protest like you go to work”.
Navalny died in February in a Russian prison. His followers say Putin was behind his death but the Kremlin denies this.
“We need to keep coming out to end the war for those in prison and in Russia who can’t come out, and for those who died there,” his widow said.
Ukrainians often accuse the Russian opposition of failing to appreciate their suffering, and failing to do enough to stop the war being waged by their country.
Oleg Orlov, co-chair of the Nobel Peace Prize-winning organisation Memorial, who was sentenced to jail in Russia for his anti-war and anti-government statements, held a banner that read: “Victory for Ukraine, Defeat for Putin, Freedom for Russia.”
Orlov now lives in Germany in enforced exile after he was released in a prisoner swap in August. He called for Ukraine’s allies to continue supplying weapons.
“Victory for Putin in Ukraine will conserve his fascist regime in Russia for many years,” he told the BBC.
“More weapons for Ukraine is important, including for the future of Russia – because if Putin wins, then Russia is defeated – that is, the Russia that all of us here dream of and that we want to build.
“Those in Europe who talk about peace at all cost in Ukraine, those prepared to appease the aggressor, do not understand the mine they are laying for the future of Europe itself.”
