Eissa ibn Musa (Arabic: عيسى بن موسى) was an Abbasid prince and a key figure and leader in the early Abbasid caliphate. As such, he was a member of the Movement of the Men of the Black Raiment. He was the nephew of Abu al-Abbas al-Saffah, the founder of the Abbasid dynasty.

Early life
Eissa ibn Musa was born in Al-Humaymah, where he grew up among the most distinguished and sagacious of his people. He was a lover of literature, a poet, and his council included notable figures such as the jurist Ibn Abi Layla, the jurist Ibn Abi Shabrama, and the literary scholar Ibn al-Samak.

Genealogy
He was a descendant of prominent figures in Islamic history, tracing his lineage back to Adnan: Isa ibn Musa, son of Muhammad, son of Ali, son of Abdullah, son of Abbas, son of Abdul-Muttalib, son of Hashim, son of Abd Manaf, son of Qusai, son of Kilab, son of Murrah, son of Ka'b, son of Lu'ayy, son of Ghalib, son of Fahr, son of Malik, son of al-Nadhar, son of Kinana, son of Khuzayma, son of Mudrikah, son of Ilyas, son of Mudar, son of Nizar, son of Ma'ad, son of Adnan. His uncle, Abu al-Abbas, appointed him as the heir to al-Mansur and governer of Kufa and its surrounding region. He was instrumental in stabilizing the Abbasid rule in the region and known for his strength and reliability. He also played a key role in the pilgrimage journeys in the years 134 and 143 AH.

Military achievements and later life
Eissa ibn Musa lived for sixty-five years and was renowned as a knight and a formidable force in the Abbasid military. He was appointed as the heir of the Abbasids by Abu al-Abbas al-Saffah after al-Mansur. He led successful campaigns against Abdullah ibn Hasan al-Muthanna's sons, thereby consolidating the Abbasid state's power. However, he was later superseded in the line of succession by al-Mahdi, the son of al-Mansur. Upon al-Mahdi's ascension to the caliphate, Isa was requested to relinquish his position as heir, which he eventually did in exchange for a substantial financial compensation.

He left behind a considerable legacy, including contributions to the planning of Baghdad, and had a river and a palace in the city named after him. The al-Akhaydir Palace, known for its fortifications, is also attributed to him, playing a crucial role in the defense of Kufa and in monitoring Alawi movements in the region. His son, Musa Bin Eissa and grandson al-'Abbas Bin Musa Bin Eissa would later also become Wali's and prominent figures in the Abbasid dynasty.
