Based on Sievers' initiative, the provincial government reform was instituted; he was himself appointed general governor of Novgorod, Tver and Pskov. He was Russian ambassador to Poland and led the second and third partition of the kingdom. Emperor Paul I of Russia appointed him senator in 1796; in 1797 he became head of the new department for water communications. He was knighted in 1798.
In Sievers' honor, Alexander I named the channel that connects the outlet of the Msta River with the Volkhov river the Sievers Canal.
Notes and references
^Regarding personal names: Until 1919, Graf was a title, translated as 'Count', not a first or middle name. The female form is Gräfin. In Germany, it has formed part of family names since 1919.
