State of Yemen
A long time passed where Yemen was isolated and the Yemenite civilization sites were beyond the interest of archaeologists who studied the sites of oriental ancient civilization.
Sana'a is one of the ancient Yemeni cities dating back to the Sabaean dynasty of the 6th Century BC. The oldest written reference to its existence is found in inscriptions which date back to the 1st century AD. It is suggested that Sana'a was the capital of the Himyarite kingdom at the onset of the 6th century AD.
