The Himyarite Kingdom was a confederation of tribes; several inscriptions and monumental buildings from this period survive and show evidence of a wealthy, sophisticated, relatively literate society with a rich variety of local gods and religions. Trade was already well established by the 3rd century AD, with Yemen supplying the Roman Empire with
frankincense and
myrrh. Furthermore, the late 1st century AD writer
Pliny the Elder mentioned that the kingdom was one of "the richest nations in the world". It was a hub of international trade, linking the Mediterranean, the Middle East, and India. The trade linking East Africa with the Mediterranean world largely consisted of exporting ivory from Africa to be sold in the
Roman Empire. Ships from Ḥimyar regularly travelled along the East African coast, and the state also exerted significant cultural, religious, and political influence over the trading cities of East Africa, whilst the cities of East Africa remained independent. The
Periplus of the Erythraean Sea describes the trading empire of Himyar and its ruler "
Charibael" (probably Karab'il Watar Yuhan'emII), who is said to have been on friendly terms with Rome:
Early period in the 1st century
Periplus of the Erythraean Sea. During this period, the Kingdom of Ḥimyar conquered the kingdoms of Saba' and Qataban and took
Raydan/Zafar for its capital instead of
Ma'rib; therefore, they have been called
Dhu Raydan (). In the early 2nd century AD, Saba' and Qataban split from the Kingdom of Ḥimyar; yet in a few decades, Qataban was conquered by
Hadhramaut (which in turn was conquered by Ḥimyar in the 4th century), whereas Saba' was finally conquered by Ḥimyar in the late 3rd century. "King of Saba, Dhu Raydan, Hadhramawt and Yamnat" (Himyarite Kingdom) 170–180 AD. Ẓafār's ruins cover an area of over 120 hectares on Mudawwar Mountain, 10 km north-north-west of the town of Yarim. Early, Empire, and Late/Post art periods have been identified. Around the same time in the north, Himyar General named Nuh Ifriqis led an expedition to
Barbaria and took control of eastern ports in modern-day Djibouti. Other Himyarite generals went as far as invading Rhapta in modern-day Mozambique. By the 4th century, the rich Himyarite export of incense, which had once supplied pagan Rome with its religious offerings, began to wane with the
Christianization of Rome, contributing to a collapse in the local economy. The conversion from polytheism and the institutionalization of Judaism as the official religion is credited in these sources to
Malkīkarib Yuha’min (r. c. 375–400). According to traditional Islamic sources, the conversion took place under his son,
Abu Karib (r. c. 400–445). It is in the mid-fourth century that inscriptions suddenly transition from polytheistic invocations to those mentioning the high god
Rahmanan, "the Lord of Heaven" or "Lord of Heaven and Earth". A Sabaic inscription dating to this time, titled Ja 856 (or Fa 60), describes the replacement of a polytheistic temple dedicated to the god
Almaqah with a
mikrāb (which might be the equivalent of a synagogue or an original form of organization local to Himyarite Judaism). The evidence suggests a sharp break with polytheism, coinciding with the sudden appearance of Jewish and Aramaic words (‘
ālam/world,
baraka/bless,
haymanōt/guarantee,
kanīsat/meeting hall) and personal names (Yṣḥq/Isaac, Yhwd’/Juda), Yws’f/Joseph). and the Jewish nature of the kings rule was not frequently made explicit.
Conversion of king Abu Karib to Judaism According to Arabian legends and folklore, king
Abu Karib (r. 390–420) was the first Jewish convert. His conversion is thought to have followed a military expedition into northern Arabia in an effort to eliminate Byzantine influence, which sought to expand its influence in the peninsula. He reached and seized
Yathrib (Medina), and there installed his son as governor. Later, he would learn that his son had been killed, and so he returned to besiege the city, during which the Jewish population fought against him. Abu Karib fell ill during the siege, but two Jewish scholars named Ka'b and As'ad were able to restore him to health. They also convinced him to lift the siege and make peace; afterwards, he and his army converted. When he returned home, he brought the scholars back with him into the capital, where he was able to convince the population to also convert. After his eventual death, it was reported that a pagan,
Dhū-Shanatir, seized the throne as his children, whom he left to rule, were all still minors.
The rise of Dhu Nuwas and the persecution of Christians in the Himyarite realms According to the
Martyrdom of Azqir, around 470-475, the Himyarite king
Sharhabil Yakkuf ordered the execution of a Christian priest named Azqir for erecting a chapel with a cross in the city of
Najran. By the year 500, during the rule of the Jewish monarch
Marthad'ilan Yu'nim (c. 400–502), the kingdom of Himyar exercised control over much of the Arabian peninsula. It was around this time that the
Kingdom of Aksum invaded the peninsula, overthrowing the Himyarite king and installing the native Christian king,
Ma'dikarib Ya'fur, in his place. A Himyarite prince and hardline follower of Judaism,
Dhu Nuwas (who had attempted to overthrow the dynasty several years earlier), took power after Ma'dikarib Ya'fur had died via a coup d'état, assuming authority after killing the Aksumite garrison in Zafār. He proceeded to engage the Ethiopian guards and their Christian allies in the
Tihāma coastal lowlands facing Abyssinia. After taking the port of
Mukhawān, where he burnt down the local church, he advanced south as far as the fortress of Maddabān overlooking the
Bab-el-Mandeb, where he expected
Kaleb Ella Aṣbeḥa to land his fleet. which is in part documented by an inscription made by Sarah'il Yaqbul-Yaz'an,
Ja 1028, which describes the burning of a church and slaughtering of Abyssinians (Ethiopian Christians), claiming thousands of deaths and prisoners. These events are also discussed in several contemporary Christian sources: in the writings of
Procopius,
Cosmas Indicopleustes,
John Malalas, and
Jacob of Serugh. Soon afterwards,
John of Ephesus (d. 588) related a letter from another contemporary, Mar Simeon, directed to Abbot von Gabula about the events. In addition, an anonymous author produced the
Book of the Himyarites, a sixth-century
Syriac chronicle of the persecution and martyrdom of the Christians of Najran. This event led to a significant counterattack by the Ethiopian kingdom, leading to the conquest of Himyar in 525–530 and the ultimate defeat and deposition of Dhu Nuwas. This signified the end of the Jewish leadership of southern Arabia, and Kaleb appointed a Christian Himyarite,
Sumyafa Ashwa, as his viceroy and vassal ruler of Himyar.
Aksumite-Sasanian Wars and the Sasanian conquest of Yemen The Aksumite general
Abraha eventually deposed Sumyafa Ashwa and took power, becoming the new ruler of Himyar.
Greater Yemen remained under firm Sasanian control until the rise of the
Islamic prophet
Muhammad in the early 7th century. ==Religion==
