Pre-6th century

The Najd region is home to Al-Magar, which was an advanced prehistoric culture of the Neolithic whose center lay in modern-day southwestern Najd. Al-Magar is possibly one of the first cultures in the world where widespread agriculture and the domestication of animals occurred, particularly that of the horse, during the Neolithic period, before climate changes in the region resulted in desertification. Radiocarbon dating of several objects discovered at Al-Magar indicate an age of about 9,000 years.

In November 2017 hunting scenes showing images of what appear to be domesticated dogs resembling the Canaan dog and wearing leashes were discovered in Shuwaymis, an area about 370 km southwest of the city of Ha'il. Dated at 8,000 years before the present, these are thought of as the earliest known depictions of dogs in the world.

In ancient times, Najd was settled by numerous tribes such as the Kindites, Tayy, and many others. Led by Usma bin Luai (Arabic: عصمة بن لؤي), the Tayy sacked the mountains of Aja and Samra from Banu Tamim in northern Arabia in their exodus from Yemen circa CE 115. These mountains are now known as the Shammar Mountains. The Tayy Shammaris became pastoral nomadic camel herders and horse breeders in northern Najd for centuries with a sedentary faction ruling the tribal league from within their capital city of Ha’il.

In the 5th century AD, the tribes of North Arabia became a major threat to the trade line between Yemen and Syria. The Ḥimyarites of Sheba decided to establish a vassal state that controlled Central and North Arabia. The Kindites, mentioned in Greek sources as the Chinedakolpitai (Greek: Χινεδακολπιται), gained strength and numbers to play that role and in AD 425 the Ḥimyarite king Ḥasan ibn 'Amr ibn Tubba’ made Ḥujr 'Akīl al-Murār ibn 'Amr the first King (Ḥujr) of Kindah. They established the Kingdom of Kinda in Najd in central Arabia unlike the organized states of Yemen; its kings exercised an influence over a number of associated tribes more by personal prestige than by coercive settled authority. Their first capital was Qaryat Dhāt Kāhil, today known as Qaryat al-Fāw.

The Ghassānids, Lakhmids and Kindites were all Kahlānī and Qaḥṭānī kingdoms which thrived in Najd. In the 5th and 6th centuries AD, the Kindites made the first real concerted effort to unite all the tribes of Central Arabia through alliances, and focused on wars with the Lakhmids. Al-Ḥārith ibn 'Amr, the most famous of their kings, finally succeeded in capturing the Lakhmid capital of al-Ḥirah in southern modern-day Iraq. Later however in about 529, al-Mundhir recaptured the city and put King Ḥārith and about fifty members of his family to death.

In 525, the Aksumites invaded Ḥimyar, and this had a knock-on effect with the Kindites, who lost the support of the Ḥimyarites. Within three years the Kindite kingdom had split into four groups: Asad, Taghlib, Qays and Kinānah, each led by a prince of Kindah. These small principalities were then overthrown in the 530s and 540s in a series of uprisings of the ‘Adnānī tribes of Najd and Ḥijāz. In 540, the Lakhmids destroyed all the Kindite settlements in Nejd, forcing the majority of them to move to Yemen. The Kindites and most of the Arab tribes switched their alliances to the Lakhmids.
