In the year 524 AD, the representatives of Sassanid, Byzantine, Lakhmids Arabs, and Himyaritic Arabs governments gathered in the district of Ramla near the city of Al-Hirah in the presence of the third Al-Mundhir Lakhmids King. The main subject of this summit was negotiations for setting the high captives of Byzantine free and forming a peace treaty between Byzantium and the third Al-Mundhir Lakhmids King who has managed to strike fatal blows and
devastating attacks on this government. However, in the middle of the meeting, the representatives of the Jewish state of Ḥimyar joined the negotiators with a letter from Dhu Nuwas, King of Yemen.
After coming to power in Yemen, Dhu Nuwas had adopted a hostile policy against the Ethiopians Christian and Byzantine government, and desired to establish an alliance between themselves and the governments of Iran and Lakhmids as the biggest rivals of the Byzantine state. Nonetheless, the diplomatic negotiations in the Ramla Summit resulted in non-cooperation of Sassanids and Lakhmids Arabs with the Ḥimyar government. This soon led to the fall of the Himyaritic dynasty in Yemen by the Byzantine and Axum :::::union:::::. Due to the fall of the Jewish Himyaritic government, the Byzantine managed to expand its influence at the shores of the Red Sea and to adopt an active policy against the interests of the Sassanid state in trading between East and West, which is among the most significant causes of Sassanid military strike on Yemen in the year 570 AD and the seizure of the territory in order to maintain a balance of power against Byzantine.
