Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in West Asia. Located in the center of the Middle East, it covers the bulk of the Arabian Peninsula and has a land area of about 2,150,000 km (830,000 sq mi), making it the fifth-largest country in Asia, the largest in the Middle East, and the twelfth-largest in the world. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Bahrain, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt and Israel. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. The capital and largest city is Riyadh; other major cities include Jeddah and the two holiest cities in Islam, Mecca and Medina. With a population of almost 32.2 million, Saudi Arabia is the fourth most populous country in the Arab world.

Pre-Islamic Arabia, the territory that constitutes modern-day Saudi Arabia, was the site of several ancient cultures and civilizations; the prehistory of Saudi Arabia shows some of the earliest traces of human activity outside Africa. Islam emerged in what is now Saudi Arabia in the early seventh century. Islamic prophet Muhammad united the population of the Arabian Peninsula and created a single Islamic religious polity. Following his death in 632, his followers expanded Muslim rule beyond Arabia, conquering territories in North Africa, Central, South Asia and Iberia within decades. Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517), and Fatimid (909–1171) caliphates, as well as numerous other Muslim states in Asia, Africa, and Europe.

The Islamization of Egypt occurred after the seventh-century Muslim conquest, in which the Islamic Rashidun Caliphate seized control of Egypt from the Christian dominated Byzantine Empire. Egypt and other conquered territories in Africa gradually underwent a large-scale conversion from Christianity to Islam, motivated in part by a jizya tax for those who refused to convert. Islam became the faith of the majority of the population at some point between the 13th and 14th centuries, and Arabic became the main language, replacing Coptic and Greek, which had previously served as the vernacular and governmental languages, respectively.

The United Arab Emirates (UAE), also known simply as the Emirates, is a country in West Asia, situated at the eastern end of the Arabian Peninsula. It is a federal semi-constitutional monarchy made up of seven emirates, with Abu Dhabi serving as its national capital. The UAE borders Oman to the east and northeast, and Saudi Arabia to the southwest; it shares maritime borders with Qatar and Iran in the Persian Gulf, and with Oman in the Gulf of Oman. As of 2024, the UAE has an estimated population of over 10 million; Dubai is the country's largest city. Islam is the majority religion and Arabic is the official language; English is the most spoken language and the language of business.

The present-day United Arab Emirates is located within the historical region of Eastern Arabia, which was oriented to maritime trade and seafaring. The Portuguese arrived in the region around 1500 and set up bases on the territory while waging wars against the Persians. After their expulsion, the Dutch controlled the straits and established global maritime dominance. By the 19th century, with pearling becoming a major economic activity, piracy became rampant in the gulf, prompting British intervention; local sheikhdoms formed a pact with the United Kingdom to create the Trucial States, a British protectorate that was effectively shielded from attempted Saudi and Omani suzerainty. The Trucial States remained under British influence until full independence as the United Arab Emirates in 1971. Zayed bin Sultan Al Nahyan, ruler of Abu Dhabi and the country's first president (1971–2004), oversaw rapid development of the Emirates by investing revenues from newly found oil into healthcare, education, and infrastructure.

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 (175,871 square miles), with a coastline of approximately 2,000 kilometres (1,200 miles), Yemen is the second largest country on the Arabian Peninsula. Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arab Muslims. 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 CE, 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 (North Yemen) following a civil war. In 1967, the People's Democratic Republic of Yemen (South 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.
