Yemen
Yemen, officially the Republic of Yemen, is a country in West Asia. Including the Socotra Archipelago, mainland Yemen is located in southern Arabia; bordering Saudi Arabia to the north, Oman to the northeast, the south-eastern part of the Arabian Sea to the east, the Gulf of Aden to the south, and the Red Sea to the west, sharing maritime borders with Djibouti, Eritrea, and Somalia across the Horn of Africa. Covering roughly 455,503 square kilometres, with a coastline of approximately, Yemen is the second largest country on the Arabian Peninsula by area, and the largest by population.
Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arab Muslims, which is estimated to be greater than that of Saudi Arabia. It is a member of the Arab League, the United Nations, the Non-Aligned Movement and the Organisation of Islamic Cooperation.
Owing to its geographic location, Yemen has been at the crossroads of many civilisations for over 7,000 years. The Sabaeans formed a thriving commercial kingdom that influenced parts of modern Ethiopia and Eritrea. In 275 AD, it was succeeded by the Himyarite Kingdom, which spanned much of Yemen's present-day territory and was heavily influenced by Judaism. Christianity arrived in the fourth century, followed by the rapid spread of Islam in the seventh century. From its conversion to Islam, Yemen became a center of Islamic learning, and Yemenite troops played a crucial role in early Islamic conquests. Much of Yemen's architecture survived until modern times. For centuries, it was a primary producer of coffee, exported through the port of Mocha. Various dynasties emerged between the 9th and 16th centuries. During the 19th century, the country was divided between the Ottoman and British empires. After World War I, the Kingdom of Yemen was established, which in 1962 became the Yemen Arab Republic following a civil war. In 1967, the People's Democratic Republic of Yemen gained its independence from the British Aden Protectorate, becoming the first and only communist state in the Middle East and the Arab world. In 1990, the two Yemeni states united to form the modern Republic of Yemen, with Ali Abdullah Saleh serving as the first president until his resignation in 2012 in the wake of the Arab Spring.
Since 2011, Yemen has been enduring a political crisis, marked by street protests against poverty, unemployment, corruption, and President Saleh's plan to amend Yemen's constitution and eliminate the presidential term limit. By 2015, the country became engulfed by an ongoing civil war with multiple entities vying for governance, including the Presidential Leadership Council of the internationally recognized government, and the Houthi movement's Supreme Political Council. This conflict, which has escalated to involve various foreign powers, has led to a severe humanitarian crisis.
Yemen is one of the least developed countries in the world, facing significant obstacles to sustainable development, and is one of the poorest countries in the Middle East and North Africa. In 2019, the United Nations reported that Yemen had the highest number of people in need of humanitarian aid, amounting to about 24 million individuals, or nearly 75% of its population. As of 2024, Yemen ranked the sixth-highest in the Fragile States Index, and as of 2020, the second-worst on the Global Hunger Index, surpassed only by the Central African Republic. As of 2024, Yemen is regarded as the world's least peaceful country by the Global Peace Index. Additionally, it is ranked 184th on the Human Development Index as of 2025. Yemen is one of the world's most vulnerable countries to climate change and among the least prepared to handle its effects.
Etymology
The term Yamnat was first mentioned in the Old South Arabian inscriptions on the title of one of the kings of the second Himyarite Kingdom known as Shammar Yahri'sh. The term probably referred to the southwestern coastline of the Arabian Peninsula and the southern coastline between Aden and Hadhramaut. Historical Yemen included much greater territory than the current nation, stretching from northern 'Asir in southwestern Saudi Arabia to Dhofar in southern Oman.One etymology derives Yemen from ymnt, meaning literally "South ", and significantly plays on the notion of the land to the right. Other sources claim that Yemen is related to yamn or yumn, meaning "felicity" or "blessed", as much of the country is fertile, in contrast to the barren land of most of Arabia. The Romans called it Arabia Felix, as opposed to Arabia Deserta.
Latin and Greek writers referred to ancient Yemen as "India", which arose from the Persians calling the Abyssinians whom they came into contact with in South Arabia by the name of the black-skinned people who lived next to them.
History
Ancient history
With its long sea border between eastern and western civilizations, Yemen has long existed at a crossroads of cultures with a strategic location in terms of trade on the west of the Arabian Peninsula. Large settlements for their era existed in the mountains of northern Yemen as early as 5000 BC. The Sabaean Kingdom existed in Yemen from 1000 BC to 275 AD. Its inhabitants were the Sabaeans, The four major kingdoms or tribal confederations in South Arabia were Saba, Hadhramaut, Qataban, and Ma'in.Sabaʾ is thought to be biblical Sheba and was the most prominent federation. The Sabaean rulers adopted the title Mukarrib generally thought to mean unifier, or a priest-king, or the head of the confederation of South Arabian kingdoms, the "king of the kings". The role of the Mukarrib was to bring the various tribes under the kingdom and preside over them all. The Sabaeans built the Great Dam of Marib around 940 BC. The dam was built to withstand the seasonal flash floods surging down the valley.
By the third century BC, Qataban, Hadhramaut, and Ma'in became independent from Saba and established themselves in the Yemeni arena. Minaean rule stretched as far as Dedan, with their capital at Baraqish. The Sabaeans regained their control over Ma'in after the collapse of Qataban in 50 BC. By the time of the Roman expedition to Arabia Felix in 25 BC, the Sabaeans were once again the dominating power in Southern Arabia. Aelius Gallus was ordered to lead a military campaign to establish Roman dominance over the Sabaeans.
The Romans had a vague and contradictory geographical knowledge about Arabia Felix. A Roman army of 10,000 men was defeated before reaching Marib. Strabo's close relationship with Aelius Gallus led him to attempt to justify his friend's defeat in his writings. It took the Romans six months to reach Marib and 60 days to return to Egypt. The Romans blamed their Nabataean guide and executed him for treachery. No direct mention in Sabaean inscriptions of the Roman expedition has yet been found.
After the Roman expedition the country fell into chaos, and two clans, namely Hamdan and Himyar, claimed kingship, assuming the title King of Sheba and Dhu Raydan. Dhu Raydan, i.e., Himyarites, allied themselves with Aksum in Ethiopia against the Sabaeans. The chief of Bakil and king of Saba and Dhu Raydan, El Sharih Yahdhib, launched successful campaigns against the Himyarites and Habashat, i.e., Aksum. El Sharih took pride in his campaigns and added the title Yahdhib to his name, which means "suppressor"; he used to kill his enemies by cutting them to pieces. Sanaa came into prominence during his reign, as he built the Ghumdan Palace as his place of residence.

The Himyarites annexed Sanaa from Hamdan around 100 AD. Hashdi tribesmen rebelled against them and regained Sanaa around 180. Shammar Yahri'sh had conquered Hadhramaut, Najran, and Tihamah by 275, thus unifying Yemen and consolidating Himyarite rule. The Himyarites rejected polytheism and adhered to a consensual form of monotheism called Rahmanism.

In 354, Roman Emperor Constantius II sent an embassy headed by Theophilos the Indian to convert the Himyarites to Christianity. According to Philostorgius, the mission was resisted by local Jews. Several inscriptions have been found in Hebrew and Sabaean praising the ruling house in Jewish terms for "...helping and empowering the People of Israel."
According to Islamic traditions, King As'ad the Perfect mounted a military expedition to support the Jews of Yathrib. Abu Kariba As'ad, as known from the inscriptions, led a military campaign to central Arabia or Najd to support the vassal Kingdom of Kinda against the Lakhmids. However, no direct reference to Judaism or Yathrib was discovered from his lengthy reign. Abu Kariba died in 445, having reigned for almost 50 years. By 515, Himyar became increasingly divided along religious lines and a bitter conflict between different factions paved the way for an Aksumite intervention. The last Himyarite king Ma'adikarib Ya'fur was supported by Aksum against his Jewish rivals. Ma'adikarib was Christian and launched a campaign against the Lakhmids in southern Iraq, with the support of other Arab allies of Byzantium. The Lakhmids were a bulwark of Persia, which was intolerant to a proselytizing religion like Christianity.
After the death of Ma'adikarib Ya'fur around 521, a Himyarite Jewish warlord called Dhu Nuwas rose to power. Emperor Justinian I sent an embassy to Yemen. He wanted the officially Christian Himyarites to use their influence on the tribes in inner Arabia to launch military operations against Persia. Justinian I bestowed the "dignity of king" upon the Arab sheikhs of Kindah and Ghassan in central and northern Arabia. From early on, Roman and Byzantine policy was to develop close links with the powers of the coast of the Red Sea. They were successful in converting Aksum and influencing their culture. The results concerning to Yemen were rather disappointing.
A Kendite prince called Yazid bin Kabshat rebelled against Abraha and his Arab Christian allies. A truce was reached once the Great Dam of Marib had suffered a breach. Abraha died around 570. The Sasanid Empire annexed Aden around 570. Under their rule, most of Yemen enjoyed great autonomy except for Aden and Sanaa. This era marked the collapse of ancient South Arabian civilization, since the greater part of the country was under several independent clans until the arrival of Islam in 630.
