ENStanislaw Doliński (1793-1873) and his son Arthur Ignatius Doliński (1831-1909), born in the territory of Lithuania and Belarus, were the representatives of a broad group of officials who made successful careers in the Russian Empire and ended up with the title of Councillor of State. Their correspondence from the years 1849-1869 is stored in the Lithuanian State Historical Archives. It reveals how the inhabitants of the north-western province became civil servants, what conditions determined their careers, everyday office work, relations with superiors and colleagues (mainly Russians), and the private side of their lives. The correspondence between father and son, who worked in the provincial cities of Russia (Novgorod, Czernichów, Poltava, Yekaterinoslav) and in St. Petersburg, is a unique source which in great detail shows the professional side of civil service, and also its emotional aspect. It is an interesting illustration of how Poles searched for their space in the nineteenth-century reality.
