Crimea Annexation (2014)
Russian troops took control of Ukraine's Crimean Peninsula, a referendum produced a reported 97% vote for joining Russia, and Moscow annexed the territory within weeks.
The West imposed sanctions on Russia and expelled it from the G8.
The annexation set a precedent for Russia absorbing neighboring territory by referendum, later applied to parts of Donbas in 2022.
Shows the full annexation playbook Russia could apply to South Ossetia after the fast-tracked integration treaties of 2026.
