query: What is the significance of the 2014 pro-Russian unrest in Ukraine?
answer: The 2014 pro-Russian unrest in Ukraine led to referendums in Donetsk and Luhansk oblasts, which sought to legitimize the establishment of self-proclaimed republics. These referendums, though not recognized internationally, were a significant escalation of the conflict and contributed to the ongoing instability in the region.  The unrest was also seen as a 'second stage' of Russian operations, mirroring the Crimean annexation.
