House of Commons maps Ukraine timeline

The House of Commons Library published an updated briefing on February 23, 2026, setting out a timeline of the Ukraine conflict from Russia’s full-scale invasion in February 2022 to the present. The paper, written by Commons Library researcher Nigel Walker, says it tracks the major events in the Ukraine-Russia conflict since the invasion and sits alongside an earlier briefing covering 2014 to the eve of the 2022 assault. (commonslibrary.parliament.uk 1) (commonslibrary.parliament.uk 2) The Library’s broader Ukraine portal groups that chronology with briefings on peace talks, military assistance, sanctions, NATO and humanitarian issues. That framing shows the conflict being followed not as a single campaign or diplomatic episode, but as a continuing policy file across Parliament’s research service. (commonslibrary.parliament.uk) The timeline does not argue a thesis. It records a sequence of offensives, failed negotiating efforts, attacks on infrastructure, foreign military support packages and sanctions measures that have accumulated over more than four years. ### What exactly did the Commons Library publish? (commonslibrary.parliament.uk) The Commons Library page says the briefing is titled “Conflict in Ukraine: A timeline (current conflict, 2022 – present)” and was published on Monday, February 23, 2026. The paper provides a chronology of major events since the 2022 invasion and directs readers to a separate briefing for the years from 2014 to early 2022. (commonslibrary.parliament.uk) Nigel Walker is listed as the author on the publication page. The Library describes itself as the research and information service based in the UK Parliament, and its briefings page says its publications are politically impartial. (commonslibrary.parliament.uk) ### How does Parliament’s research service place this timeline in a wider Ukraine file? The House of Commons Library’s Ukraine landing page says its research covers military assistance, sanctions, international legal issues and efforts to resolve the conflict. The same page describes Russia’s February 24, 2022 action as a “special military operation” in Moscow’s terms and says Ukraine’s allies and partners have condemned Russia’s actions and provided military and financial support. (commonslibrary.parliament.uk) That page also says investigations into possible war crimes, including by the International Criminal Court, are under way, and that a Western-led sanctions package has been imposed on Russia. (commonslibrary.parliament.uk) The Library links the timeline to a set of continuing policy questions rather than to a closed historical episode. ### What details in the surrounding briefings show how broad the conflict file has become? A separate Commons Library humanitarian briefing published in February 2026 says more than 14,999 civilians were killed between February 2022 and December 2025, while warning that the figure is likely an underestimate according to U.N. monitors. The same paper says 10.8 million people in Ukraine need humanitarian assistance in 2026. (commonslibrary.parliament.uk) Another Commons Library briefing says the UK has pledged £21.8 billion in support to Ukraine since February 2022, including £13.06 billion in total military financing. That paper says the UK has been one of the leading donors alongside the United States and Germany. (commonslibrary.parliament.uk) ### What do the peace-talk and military-aid papers add to the picture? A Commons Library peace-talks briefing published two months ago says three rounds of talks among U.S., Ukrainian and Russian officials in the United Arab Emirates and Switzerland in late January and February 2026 did not produce a breakthrough. The paper says further talks planned for early March 2026 in the United Arab Emirates were postponed because of U.S./Israeli military action against Iran. (commonslibrary.parliament.uk) A March 9, 2026 military-assistance briefing says President Donald Trump adopted a significantly different approach to Ukraine after taking office in January 2025. That paper also cites April remarks by European leaders that “Ukraine’s security is inseparable from Euro-Atlantic security.” (commonslibrary.parliament.uk) ### Where can readers follow the next updates? The Commons Library says the February 23, 2026 timeline is part of a live set of Ukraine publications, including the peace-talks briefing that “will be updated as the issue develops.” The Library’s Ukraine portal also links to current papers on sanctions, military aid and proposals for a “Coalition of the Willing” tied to any future peace deal.
