Saadian invasion of the Songhai Empire in the context of Arma people

The Saadi Sultanate (Arabic: السعديون, romanized: as-saʿdiyyūn), also known as the Sharifian Sultanate (Arabic: السلطنة الشريفة), was a state which ruled present-day Morocco and parts of Northwest Africa in the 16th and 17th centuries. It was led by the Saadi dynasty, an Arab Sharifian dynasty.

The dynasty's rise to power started in 1510, when Muhammad al-Qa'im was declared leader of the tribes of the Sous valley in southern Morocco in their resistance against the Portuguese who occupied Agadir and other coastal cities. Al-Qai'm's son, Ahmad al-Araj, secured control of Marrakesh by 1525 and, after a period of rivalry, his brother Muhammad al-Shaykh captured Agadir from the Portuguese and eventually captured Fez from the Wattasids, securing control over nearly all of Morocco. After Muhammad al-Shaykh's assassination by the Ottomans in 1557 his son Abdallah al-Ghalib enjoyed a relatively peaceful reign. His successors, however, fought with each other, culminating in the 1578 Battle of Ksar el-Kebir (or "Battle of the Three Kings"), where a Portuguese military intervention on behalf of Muhammad II al-Mutawakkil was thoroughly defeated by Saadian forces. In the wake of this victory, Ahmad al-Mansur became sultan and presided over the apogee of Saadian power. In the later half of his reign he launched a successful invasion of the Songhai Empire, resulting in the establishment of a Pashalik centered on Timbuktu. After Al-Mansur's death in 1603, however, his sons fought a long internecine conflict for succession which divided the country and undermined the dynasty's power and prestige. While the Saadian realm was reunified at the end of the conflict in 1627, new factions in the region rose to challenge Saadian authority. The last Saadian sultan, Ahmad al-Abbas, was assassinated in 1659, bringing the dynasty to an end. Moulay al-Rashid later conquered Marrakesh in 1668 and led the 'Alawi dynasty to establish a new sultanate over Morocco.

The Pashalik of Timbuktu, also known as the Pashalik of Sudan, was a West African political entity that existed between the 16th and the 19th century. It was formed after the Battle of Tondibi, when a military expedition sent by Saadian sultan Ahmad al-Mansur of Morocco defeated the Songhai Empire and established control over a territory centered on Timbuktu. Following the decline of the Saadi Sultanate in the early 17th century, Morocco retained only nominal control of the Pashalik.

Judar Pasha (Arabic: جؤذر باشا) was a Spanish-Moroccan military leader under the Saadian sultan Ahmad al-Mansur in the late 16th century. He led the Saadian army in the conquest of the Songhai Empire.

Born as Diego de Guevara in Cuevas del Almanzora, Castile, Judar had been captured by Muslim slave-raiders as a young boy. His captors castrated him. As a young boy, he joined the service of Moroccan Sultan Ahmad al-Mansur, who had many other eunuch officers. Judar was often described by reference to his blue eyes.

The Battle of Tondibi was the decisive confrontation in the 16th-century invasion of the Songhai Empire by the army of the Saadi dynasty in Morocco. The Moroccan forces under Judar Pasha defeated the Songhai under Askia Ishaq II, guaranteeing the empire's downfall.
