Madaba (مادبا; Biblical Hebrew: Mēḏəḇāʾ; Μήδαβα) is the capital city of Madaba Governorate in central Jordan, with a population of about 60,000. It is best known for its Byzantine and Umayyad mosaics, especially a large Byzantine-era mosaic map of the Holy Land. Madaba is located south-west of the capital Amman.
Madaba dates from the Middle Bronze Age.
The town of Madaba was once a Moabite border city, mentioned in the Bible in Numbers 21:30 and Joshua 13:9. Control over the city changed back and forth between Israel and Moab, as mentioned in the Mesha Stele.
During its rule by the Roman and Byzantine empires from the 2nd to the 7th centuries, the city formed part of the Provincia Arabia set up by the Roman Emperor Trajan to replace the Nabataean kingdom of Petra.
The first evidence for a Christian community in the city, with its own bishop, is found in the Acts of the Council of Chalcedon in 451, where Constantine, Metropolitan Archbishop of Bostra (the provincial capital) signed on behalf of Gaiano, "Bishop of the Medabeni." It was conquered by the Rashidun Caliphate in 629 after the Battle of Mut'ah.
During the rule of the Islamic Umayyad Caliphate, it was part of the southern district of Jund Filastin within the Bilad al-Sham province.
In 1880, 90 Arab Christian families from Al Karak resettled the ruins of Madaba, led by two Italian priests from the Latin Patriarchate of Jerusalem. This period saw the start of archaeological research. This in turn substantially supplemented the scant documentation available.
The Catholic Church's list of titular sees uses the spelling "Medaba", in reference to the ancient bishopric located in this city, while referring to the modern city as "Madaba".
Today, the city is the seat of Madaba Governorate and is the 9th-biggest city in Jordan, with a population of 122,008 as of 2021.
The first mosaics were discovered during the building of new houses using bricks from older buildings. The new inhabitants of Madaba, made conscious of the importance of the mosaics by their priests, made sure that they took care of and preserved all the mosaics that came to light.
