What is the opposite of 'allegiance'?

The term 'allegiance' refers to a person's loyalty or commitment to a group, cause, or government. Therefore, the opposite would be a concept that implies a lack of loyalty or support towards that group or cause. 'Betrayal' effectively captures this idea, as it involves the act of being disloyal or unfaithful, especially to a promise or trust that has been placed in someone.

The other concepts such as 'commitment,' 'loyalty,' and 'devotion' all convey a sense of fidelity or attachment to a cause or group, which stands in contrast to betrayal. Understanding allegiance and its opposites can help clarify discussions surrounding citizenship, responsibilities, and personal relationships within various contexts.
