Russia-Ukraine gas disputes (2006 and 2009)
January 2006 - January 2009What Happened
Russia cut off gas supplies through Ukraine twice—briefly in January 2006, then for 13 days in January 2009. The 2009 cutoff left over a dozen European countries scrambling for heat in midwinter, with Bulgaria, Slovakia, and the Balkans completely cut off. The disputes were nominally over pricing and transit fees between Moscow and Kyiv.
Outcome
Both crises ended with negotiated deals restoring supply, but exposed Europe's dangerous dependence on a single transit route controlled by two adversaries.
The 2009 crisis drove the EU to build the Southern Gas Corridor and invest in liquefied natural gas terminals, beginning a slow diversification away from Russian pipeline gas that accelerated after the 2022 invasion.
Why It's Relevant Today
The current dispute inverts the pattern: instead of Russia cutting supply to pressure Ukraine, EU member states are threatening to cut electricity to Ukraine to protect their Russian oil supply. The dependency that Europe spent 15 years trying to reduce is now being wielded by the dependent states themselves.
