Headquarters Multinational Corps Northeast has been operating since 18 September 1999 – the year when Poland joined NATO. The Corps was established by a treaty signed in 1998 by the ministers of defence of Denmark, Germany and Poland. The three countries are the so-called Framework Nations of the Corps. Initially, we operated solely based on the partnership between these Allies from the Baltic Sea region and our fundamental task was to foster trilateral cooperation. The first additional countries to join the Headquarters were Estonia, Latvia and Lithuania in 2004. Since then, our team has gradually grown and now consists of 24 nations.
The NATO Wales Summit of 2014 came at a critical time in the Alliance's history. The global security environment took a turn for the worse and revealed to be highly unpredictable. Russia's actions against Ukraine have challenged NATO to increase its military presence in the Baltic Sea area. That is when it was decided that Headquarters Multinational Corps Northeast would develop in order to be able to respond promptly to any possible crisis as well as to provide NATO with the capability to command forces deployed to Estonia, Latvia, Lithuania and Poland. Thus, in 2017 our combat readiness was upgraded from low to high. Today, we are on permanent stand-by to take the lead in NATO's land operations across the whole Baltic region.
