The Hamina Cadet School and Finland Cadet School were the common names for the Fredrikshamn cadet school during the period 1819–1901. The Cadet School was founded in 1780 by Georg Magnus Sprengtporten at Kuopio and transferred in 1781 to Rantasalmi where it was called Haapaniemi Cadet School. In 1819, after the School was transferred to Hamina (Swedish: Fredrikshamn) the name was changed accordingly, in common usage. After Finnish independence in 1917 the Cadet school was moved to Santahamina in Helsinki.In the 1920 the premises were occupied by the Reserve Officer School of the newly formed Finnish defence forces. Today the main building of the Cadet school hosts the headquarters of the Reserve Officer School of the Finnish Army. Hamina Cadet School was abolished in 1903 with the abolition of the separate Army of the Grand duchy of Finland as part of the Russification policy. The conscription of Finnish soldiers directly to various units of the Russian Empire was seen as illegal and unconstitutional in Finland. Finnish officers protested first in through mass resignations and later through a strategy of disobedience, in what is now known as the conscription strikes. Finally it was settled that the Grand Duchy of Finland would fulfil its obligation to the common defence with a monetary compensation to the Russian Empire instead through the provision of conscripts.
