The Minister–Secretary of State for Finland (in Finnish Ministerivaltiosihteeri; in Swedish Ministerstatssekreterare) represented Finnish interests in the Imperial Court in Saint Petersburg. Before 1834 the title was secretary of state. The Russian Tsar was represented in Helsinki, the capital of the Grand Duchy of Finland by the Governor General.
After Speransky (whose term had yet the Committee for Finnish Affairs as another actor in same matters), this State Secretary was required, as were Senators and so forth, to be a subject of the grand duchy.
This secretary of state was an official who, and whose office (there were deputy and assistants) had the monopoly to present Finnish affairs to the Emperor. All acts of the Emperor concerning the grand duchy, were to be countersigned by this State Secretary, or deputized officials. When the Finnish autonomy was establishing, other Finnish-related officials generally supported, and helped to build this monopoly (to mention, Governor-General Alexander Sergeyevich Menshikov was a supporter of this particularism and although he resided in St Petersburg and was in close contact with the emperor as simultaneous Russian Minister of Navy, he consistently had Finnish affairs to go through the Minister State Secretary). The tradition, endorsed by conservative Emperors such as Nicholas I, created a strong precedent. Russian general government was effectively kept out of Finnish affairs, this Minister having the benefit of the channel, and many possibilities to stall Russian ministers. Only in last two decades of the grand duchy, those periods of russification, the system was attempted to be broken in some regards, but it created counteroffensives based on illegality arguments. Plehwe's appointment was criticized as illegal, because he was not Finnish citizen. Afterwards, russified Finnish citizens were occasionally used in this office and as members of the senate in Helsinki.
