The Republic of Indian Stream was a small, unrecognized, constitutional republic in North America, along the section of the US-Canada border that divides the Canadian province of Quebec from the US state of New Hampshire. It existed from July 9, 1832 to 1835. Described as "Indian Stream Territory, so-called" by the United States census-taker in 1830, the area was named for Indian Stream, a small watercourse. It had an organized elected government and constitution, and served about three hundred citizens. The Republic ceased to operate independently in 1835 when the New Hampshire Militia occupied the area, following a vote by the Indian Stream Congress authorizing annexation to the United States. The vote arose from disquiet regarding a prior incident in which a group of "streamers" invaded Canada to free a fellow citizen who had been arrested by a British sheriff and magistrate. The invading posse shot up the judge's home where their comrade was being held, and this caused a diplomatic crisis, a so-called 'international incident'.
