who directed the rebuilding of the wall of jerusalem
Nehemiah In the 20th year of Artaxerxes, king of Persia, (445/444 BC), Nehemiah was cup-bearer to the king.[5] Learning that the remnant of Jews in Judah were in distress and that the walls of Jerusalem were broken down, he asked the king for permission to return and rebuild the city.[6] Artaxerxes sent him to Judah as governor of the province with a mission to rebuild, letters explaining his support for the venture, and provision for timber from the king's forest.[7] Once there, Nehemiah defied the opposition of Judah's enemies on all sides—Samaritans, Ammonites, Arabs and Philistines—and rebuilt the walls within 52 days, from the Sheep Gate in the North, the Hananeel Tower at the North West corner, the Fish Gate in the West, the Furnaces Tower at the Temple Mount's South West corner, the Dung Gate in the South, the East Gate and the gate beneath the Golden Gate in the East.
History of Jerusalem during the Middle Ages Jerusalem reached a peak in size and population at the end of the Second Temple Period: The city covered two square kilometers (0.8 sq mi.) and had a population of 200,000.[2][3] In the five centuries following the Bar Kokhba revolt in the 2nd century, the city remained under Roman then Byzantine rule. During the 4th century, the Roman Emperor Constantine I constructed Christian sites in Jerusalem such as the Church of the Holy Sepulchre.
