In summer 1944 Hackzell was chosen to form a government with the goal of signing a peace treaty with the Soviet Union. Hackzell suffered a stroke in Savoy Hotel in Moscow while on peace treaty negotiations on 14 September, and he never recovered completely. His minister of foreign affairs, Carl Enckell, concluded the negotiations.
Family origins
The Hackzell family name derives from the Hacksta family estate, located in Hacksta, Uppland in Sweden. Through Mårten Hackzell, the only child of the Uppland clergyman Andreas Hackzelius,[4][5] and through Mårten's offspring, the Hackzell family spread to Norrland and Finland.
