Founded in 1986, Harvard Model Congress is the largest congressional simulation conference in the world run entirely by Harvard undergraduates, organized as a nonprofit. Its flagship event, HMC Boston, takes place each February in Cambridge, Massachusetts, with the 2027 conference scheduled for February 18-21.
About 40 committees are offered, covering House and Senate legislative committees as well as judicial bodies such as a District Court and executive or intelligence bodies such as the Permanent Select Committee on Intelligence.
Delegates receive background material in advance, are assigned a role and issue set, and spend the conference speaking, debating, drafting and amending legislation, and voting, all chaired and staffed by Harvard undergraduates at roughly a 9:1 delegate-to-staffer ratio.
Strictly speaking HMC is an immersive civics and politics training program rather than a ranked academic competition; it is grouped with history here because its demands on American political institutions, constitutional structure, and policy history complement history coursework and debate training closely.
Registration for 2027 opened September 1, 2026 and closes November 30, 2026, for both school delegations and unaffiliated individual delegates, with a scholarship track available. Harvard Model Congress also runs separate Europe, Asia, and Middle East conferences with their own registration.
