Al-Yamama

Al-Yamama (Arabic: اليَمامَة, romanized: al-Yamāma) is a historical region in the southeastern Najd in modern-day Saudi Arabia, or sometimes more specifically, the now-extinct ancient village of Jaww al-Yamamah, near al-Kharj, after which the rest of the region was named.

Only a handful of centralized states ever arose in the Yamama, but it figured prominently in early Islamic history, becoming a central theater in the Ridda wars immediately following Muhammad's death. Despite being incorporated into the Najd region, the term 'al-Yamama' remains in use as a traditional and historical term to reference or emphasize the region's ancient past. The current headquarters of the Saudi government in Riyadh, for example, is known as the Palace of Yamamah.
