إب( Ibb )
Ibb (Arabic: إِبّ, romanized: ʾIbb) is a city in Yemen, the capital of Ibb Governorate, located about 117 km (73 mi) northeast of Mocha and 194 km (121 mi) south of Sana'a. A market town and administrative centre developed during the Ottoman Empire, it is one of the most important medium-sized cities in the country. It is situated on a mountain ridge, surrounded by fertile land. As of 2005, it had a population of 160,000.
Ibb has been occupied since ancient times, and due to its strategical importance, the Ottomans used it as an administrative centre. It thrived as a market town and the Ottomans established the Wednesday market in Ibb. Ibb was governed by a semi-autonomous emir until 1944, when the emirate was abolished. At times in its history many people have migrated to Ibb from areas of Yemen which had been experiencing drought, to find work in farming. In the mid 1950s there was reportedly an outbreak of smallpox in the city.
German explorer, Hermann Burchardt, photographed the city in 1901, photos now held at the Ethnological Museum of Berlin.
