Timeline of Events in the Build-up to the Russo-Ukrianian War

On February 24, 2022, President of the Russian Federation Vladimir Putin launched a full-scale invasion of Ukraine. In response to this "brutal assault”, the United States, the European Union, the United Kingdom, Canada, Australia, Japan, and Taiwan all leveled a heavy set of economic sanctions against Russia. With war looming, Poland, Slovakia, Hungary, Romania, and Germany all announced that they were preparing for an influx of refugees from Ukraine.


How did we get here? What are some of the key reasons and events that led to this disaster that promises to be one of the largest on the European continent since WWII? Here, I will list out some of the most pivotal events that have happened between Ukraine, the West, and Russia in the lead-up to the Russo-Ukranian War.
