Which crime involves an agreement between two or more persons to commit an illegal act?

Conspiracy is defined as an agreement between two or more persons to commit an illegal act, along with an overt act in furtherance of that agreement. This crime emphasizes the collaborative nature of planning to engage in illegal conduct, even if the act itself has not yet been completed. The essence of conspiracy lies in the intention and agreement to achieve a criminal objective, which can encompass a variety of illegal acts.

Attempt, while it involves an effort to commit a crime, does not require a mutual agreement between parties. Burglary specifically pertains to unlawfully entering a structure with the intent to commit a crime inside, which may or may not involve agreements with others. Robbery involves taking property from another through force or intimidation and does not inherently involve an agreement among individuals to commit the crime. Thus, conspiracy distinctly captures the aspect of agreement that is central to the crime in question.
