The act of betraying one's country by cooperating with an enemy that has taken control.
The government was accused of quislingism for working with the invading forces.
Quislingism is derived from 'Quisling' (from the name of Vidkun Quisling, a Norwegian politician who collaborated with the Nazis during World War II) and the suffix '-ism' (meaning a practice or ideology). The term refers to the act of betraying one's own country by collaborating with an enemy power, particularly in a political context.
Think of Vidkun Quisling, who betrayed his country, to remember that 'quislingism' means collaborating with an enemy against one's own nation.
