Davidic line is Uzziah, who reigned in the 8th century BCE, about 75 years after Ahaziah, who is named on bullae seals belonging to his servants Abijah and Shubnayahu. Uzziah may also be mentioned in the annals of Tiglath-Pileser III; however, the texts are largely fragmentary. Additionally, a tombstone dated to the Second Temple Period claiming to mark the grave (or, reburial) site of Uzziah, was discovered in a convent on the Mount of Olives in 1931, but there is no way of determining if the remains were genuinely Uzziah's as the stone had to have been carved more than 700 years after Uzziah died and was originally interred, and the tablet's provenance remains a mystery. A controversial artifact called the Jehoash Tablet recalls deeds performed by Jehoram of Judah, who reigned about 44 years before Uzziah; however, scholars are tensely divided on whether or not the inscription is genuine. After Uzziah, each successive king of Judah is attested to in some form, with the exception of Amon of Judah: Jotham, Uzziah's successor, is named on the seals of his own son and successor, Ahaz, who ruled from 732 to 716 BCE. Hezekiah, Ahaz's son, is attested to by numerous royal seals and Sennacherib's Annals; Manasseh is recorded giving tribute to Esarhaddon; Josiah has no relics explicitly naming him; however, seals belonging to his son Eliashib and officials Nathan-melech and Asaiah have been discovered; and the kings Jehoahaz II, Jehoiakim, and Zedekiah are never explicitly named in historical records but are instead alluded to; however, Jeconiah is mentioned by name in Babylonian documents detailing the rations he and his sons were given while held prisoner during the Babylonian captivity. The origins of the dynasty, on the other hand, are shrouded in mystery. The Tel Dan Stele, as aforementioned, remains the only mention of David himself outside the Bible, and the historical reliability of the United Monarchy of Israel is archaeologically weak. The Stepped Stone Structure and Large Stone Structure in Jerusalem, assuming Eilat Mazar's contested stratigraphic dating of the structures to the Iron Age I is accurate, show that Jerusalem was at least somewhat populated in King David's time, and lends some credence to the biblical claim that Jerusalem was originally a Canaanite fortress; however, Jerusalem seems to have been barely developed until long after David's death, bringing into question the possibility that it could have been the imperial capital
