KYIV, July 15 — Russia’s occupation of roughly 18 percent of Ukrainian territory is now in its twelfth year, a slow consolidation that began with Crimea in 2014 and accelerated after the full-scale invasion of 2022. The mechanics here are territorial control followed by administrative absorption, and the pattern is consistent across four regions Moscow claims as its own. The timeline matters.
Russia annexed Crimea in March 2014 after a disputed referendum. In April of that year, pro-Russian separatists in the Donbas — Donetsk and Luhansk oblasts — declared independence with Moscow’s backing.
Then came the 2022 invasion, which added large chunks of Zaporizhzhia, Kherson, and parts of Kharkiv and Mykolaiv under Russian military control. In September 2022, Russia formally claimed annexation of Donetsk, Luhansk, Zaporizhzhia, and Kherson. The United Nations General Assembly condemned that move as illegal under Resolution ES-11/4, passed in October 2022.
The territorial breakdown
As of 2025, Russia holds 100 percent of Crimea. In Luhansk, it controls about 98 percent. In Donetsk, roughly 60 percent.
In Zaporizhzhia, about 75 percent. In Kherson, about 70 percent.
The catch is that these are not static front lines — Ukraine recaptured Kherson city in November 2022 and parts of Kharkiv oblast in September 2022, pushing Russian forces back in those sectors. But the broader occupation belt remains in place, and Moscow has not relinquished its legal claims to any of it. On closer reading, the occupation strategy goes beyond military hold.
Russian authorities have issued passports to residents in the occupied territories and suppressed the Ukrainian language. Forced Russification is the stated policy, not a side effect.
The International Criminal Court took note: in March 2023, it issued arrest warrants for President Vladimir Putin for alleged war crimes related to the deportation of children from occupied Ukraine.
Follow the legal paper trail
The annexation claims sit on a shaky legal foundation. The UN General Assembly resolution from October 2022 was clear — the attempted annexation has no validity under international law. But Russia has proceeded as if the votes and the borders are settled.
The practical consequence is that any business operating in those territories, any property transaction, any administrative action taken under Russian law, exists in a legal gray zone that neither Ukraine nor most of the international community recognizes. The pattern is not new.
Crimea’s annexation in 2014 set the template: a disputed referendum, a swift integration into Russian administrative structures, passport issuance, currency conversion, and the replacement of Ukrainian-language education with Russian. The Donbas followed a slightly different path — separatist entities first, then formal absorption after 2022. Zaporizhzhia and Kherson, where Ukrainian forces still hold parts of the territory, remain contested.
What to watch next is whether Russia can hold the roughly 18 percent it controls against continued Ukrainian counteroffensives, and whether the forced integration measures — passports, language policy, child relocation — will generate additional international legal action beyond the existing ICC warrants. The occupation is not static, but the administrative machinery grinding through it is.
