What is the legal definition of sedition?

The legal definition of sedition primarily encompasses actions or speech that incite rebellion against the authority of a state or government, particularly in a manner that is intended to undermine its authority. Inciting hatred against the government or monarch captures this essence, as it refers to communication designed to provoke discontent or opposition towards the established authority, which can potentially lead to actions that disrupt stable governance.

The other choices do touch upon related concepts but do not precisely encapsulate the legal understanding of sedition. Encouraging violence against a community relates to hate crimes or violence rather than the specific act of undermining state authority. Aiding enemies of the state would be more aligned with treasonous actions, which is a separate legal classification with different implications. Gathering in rebellion suggests a physical aspect of rebellion but does not necessarily include the broader communicative actions or speech that the term 'sedition' encompasses. Thus, inciting hatred against the government accurately reflects the legal definition of sedition in the context of undermining state authority through words or actions.
