Aden is the UK's AY-d@n and US's AH-den. It is located near the Red Sea (the Gulf of Aden) at 170 km (110 miles) east of Bab-el-Mandeb. The city is home to approximately 800,000. Aden's natural harbour is located in the crater a dormant volcano. It now forms a peninsula that connects to the mainland via a low isthmus. Front Bay was the first harbour to be used by the ancient Kingdom, Awsan, between the 7th and 5th centuries BC. On the opposite side of the peninsula is the modern harbour. The Gulf of Aden is named after Aden.
Aden is made up of several sub-centres. Crater was the original port city. Maalla was the modern port. Tawahi, also known as Steamer Point during colonial times, and the resorts at Gold Mohur are all part of the main centre. Khormaksar is located on the isthmus connecting Aden with the mainland. It houses the city's diplomatic missions and the main offices for Aden University. Aden International Airport, which was formerly the British Royal Air Force station RAF Khormaksar (Yemens second largest airport), is also here. The sub-centres and Al-Mansura are located on the mainland. These were once an oasis area. Madinat ash-Shab, formerly Madinat al-Itihad, is now the capital of South Arabian Federation. It also houses Aden University's large power/desalinization plant and additional faculties.
Aden surrounds the eastern end of the vast, natural harbour that forms the modern port. This made it necessary to create the Cisterns at Tawila, Aden's reservoirs.
According to Ibn Battuta (14th-century scholar), these reservoirs store rainwater solely for the purpose of drinking by the citizens. It is a prosperous city with many wealthy merchants and Indian ships arriving to trade. The port and harbour on the west side are enclosed by the volcanic peninsula of Little Aden. Little Aden was the location of the oil refinery, and the tanker port. They were both established by British Petroleum and were operated until 1978 when they were handed over to the Yemeni government.
Aden was the capital of Peoples Democratic Republic of Yemen from 1990 to its unification with Yemen Arab Republic. It briefly served again as Yemen's temporary capital after the Houthi takeover of Yemen. This was declared by President Abd Rabbuh Mansur Hadi following his escape from the Houthi occupation of Sanaa. The Battle of Aden was fought between President Hadi's government forces and the Houthis from March 2015 to July 2015. The city was short of water, food, and medical supplies. The Saudi Army launched an offensive on 14 July to retake Aden in support of the Yemeni government. The Houthis were expelled from Aden within three days. The Southern Transitional Council has seized Aden since February 2018. Supported by UAE, the Southern Transitional Council has taken control of Aden. Former Mayor Aidroos Alzubaidi was fired by Abdrabbuh Mansur Hadi and sacked ex-Minister Salfi-religious leader Hani Bin Buraik.
