The Imperial Order of the Rose (Portuguese: Imperial Ordem da Rosa) was a Brazilian order of chivalry, instituted by Emperor Pedro I of Brazil on 17 October 1829 to commemorate his marriage to Amélie of Leuchtenberg. On 22 March 1890, the order was cancelled as national order by the interim government of First Brazilian Republic. Since the deposition in 1889 of the last Brazilian monarch, Emperor Pedro II, the order continues as a house order being awarded by the Heads of the House of Orleans-Braganza, pretenders to the defunct throne of Brazil. The current Brazilian Imperial Family is split into two branches Petrópolis and Vassouras, and as a consequence the Grand Mastership of the Order is disputed between those two branches.
