The Flagstaff War, also known as Heke's War, Hōne Heke's Rebellion and the Northern War, was fought between 11 March 1845 and 11 January 1846 in and around the Bay of Islands, New Zealand. The conflict is best remembered for the actions of Hōne Heke who challenged the authority of the British by cutting down the flagstaff on Flagstaff Hill (Maiki Hill) at Kororāreka (now Russell). The flagstaff had been a gift from Hōne Heke to James Busby, the first British Resident. The Northern War involved many major actions, including the Battle of Kororāreka on 11 March 1845, the Battle of Ōhaeawai on 23 June 1845 and the siege of Ruapekapeka Pā from 27 December 1845 to 11 January 1846.
