treasonous acts

Crimes against country

Treasonous acts are actions that betray one's country or sovereign, typically by aiding enemies, attempting to overthrow the government, or otherwise undermining national security.

The phrase emphasizes conduct rather than mere intent or allegiance—it's about what someone actually did.

The prosecution argued that passing classified documents to foreign agents constituted treasonous acts.

In casual use, people sometimes apply the term hyperbolically to any perceived disloyalty or betrayal of a group's interests.
