Alexei Navalny was a prominent Russian opposition leader, lawyer, and anti-corruption activist who became the most significant domestic challenger to President Vladimir Putin’s administration. His career was defined by high-profile investigations into government graft, multiple politically motivated imprisonments, and a near-fatal poisoning attempt that drew international condemnation. Following his death in a remote Arctic penal colony in early 2024, Navalny remains a central figure in global discourse regarding human rights, the state of Russian democracy, and the geopolitical tensions surrounding the Kremlin’s crackdown on political dissent.
