A report on Arabian Peninsula

Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country on the Arabian Peninsula in Western Asia.

Yemen (ٱلْيَمَن), officially the Republic of Yemen (ٱلْجُمْهُورِيَّةُ ٱلْيَمَنِيَّةُ, ), is a country in Western Asia, on the southern end of the Arabian Peninsula.

The first mention of Arabs appeared in the mid-9th century BCE, as a tribal people in eastern and southern Syria and the northern Arabian Peninsula.

Najd (نَجْدٌ, ), or the Nejd, forms the geographic center of Saudi Arabia, accounting for about a third of the country's modern population and, since the Emirate of Diriyah, acting as the base for all unification campaigns by the House of Saud to bring Arabia under a single polity and under the Salafi jurisprudence.

It is situated on the southeastern coast of the Arabian Peninsula, and spans the mouth of the Persian Gulf.

It is named after the Arabs, a term initially used to describe people living in the Arabian Peninsula bounded by eastern Egypt in the west, Mesopotamia in the east, and the Anti-Lebanon mountains and northern Syria in the north, as perceived by ancient Greek geographers.

It is located at the eastern end of the Arabian Peninsula and shares borders with Oman and Saudi Arabia, while having maritime borders in the Persian Gulf with Qatar and Iran.

At its height, the empire was the strongest military power in the world and ruled over all of Mesopotamia, the Levant and Egypt, as well as portions of Anatolia, Arabia and modern-day Iran and Armenia.

Shariah law exists partially in the legal system in some countries (especially in the Arabian peninsula), while others are legislatively secular.

Classically, Syria lies at the eastern end of the Mediterranean, between Arabia to the south and Asia Minor to the north, stretching inland to include parts of Iraq, and having an uncertain border to the northeast that Pliny the Elder describes as including, from west to east, Commagene, Sophene, and Adiabene.
