US Navy ships. In that port and, later at Angra, cannon and other supplies of war were transferred aboard the new ship. The CSS Alabama was commissioned on 24 August 1862 just outside the harbor of Angra, and it left Terceira to begin its career as the most effective commerce raider in naval history. Ngungunhane (also known as Mdungazwe Ngungunyane Nxumalo, N'gungunhana, or Gungunhana Reinaldo Frederico Gungunhana) was born in Gaza in southern Africa around 1850, and he died at Angra do Heroísmo on 23 December 1906. A vassal of the Portuguese king, he later rebelled, and he was defeated and imprisoned by the Portuguese Army, led by Joaquim Mouzinho de Albuquerque. He was exiled to Lisbon and then to the island of Terceira, where he converted to Catholicism; he lived there until his death. He was the last emperor of the Empire of Gaza, a territory that is now part of Mozambique, and he was the last monarch of his dynasty. Nicknamed the "Lion of Gaza", he reigned from 1884 to 28 December 1895, the day he was made prisoner by Joaquim Mouzinho de Albuquerque in the fortified village of Chaimite. Because he was already known to the European press, the Portuguese colonial administration decided to condemn him to exile rather than send him to face a firing squad, as would normally be the case. He was transported to Lisbon, accompanied by a son named Godide and other dignitaries. After a brief stay, he was transferred to Angra do Heroísmo, where he died eleven years later. 20th century Angra was hit by a major earthquake on 1 January 1980 that did considerable damage to the city's historic center and to many other locations on the island of Terceira. The Azores have experienced many earthquakes and volcanic eruptions since prehistoric times, but the 1980 event was probably the most serious since the eighteenth century. The damage in the city was repaired and rebuilt within four years. In 1983, the historic center of Angra do Heroísmo was named a UNESCO World Heritage Site.
