The purpose of this essay is to examine the national office, landskansliet, in Västmanland's submitted passport extracts for domestic voyages in Västmanland according to the strengthened requirements, which meant that all travellers had to hold passports, in 1812 royal orders. The passport constraint is analysed as a tool for exercising power, based on Michael Foucaults theory of power and knowledge. The method that is used is a qualitative text analysis. This essay shows that the passport constraint can be analysed based on Foucaults power and knowledge. That the two concepts are closely linked in the case of the landskansli legitimate use of the passport constraint as a means of power. Power is different depending on who it was that travelled. Against some people the exercise of power is greater than others. Above all, the degree of power is greater against servants who travelled without company, foreigners, workers and the unemployed. This is evident in the "special notes" field that the landskansli used in the passport extracts. The survey also shows that residents who travelled between places in the county didn’t have to apply for a passport. Hence the power targets only those who intended to travel across the county borders or whether they were just passing through the county. Travellers who passed through were obliged to show their passports to the landskansli. Even the magistrate in the county's cities had the right to issue passports for those who applied for travel. This meant that the landskansli did not have a monopoly over the passport constraint in the county.
