The Talmudic authority who led a Muslim kingdom's army into battle for nearly two decades
Shmuel HaNagid was one of the great Hebrew poets and halachic authorities of Sepharad — the Nagid who appointed the community's judges and headed its Talmudic academy. He was also the vizier of the Muslim kingdom of Granada and the battlefield commander of its army, a post he held from about 1038 until his death around 1056, and in which he personally led its forces into battle for some sixteen of those roughly eighteen years.
How we know
Samuel ibn Naghrela HaNagid (993–1056). Under Badis of Granada (king from 1038) he served as vizier and battlefield commander of Granada's army until his death c.1056 — roughly eighteen years, of which he led the army into battle for about sixteen (Peter Cole, Selected Poems of Shmuel HaNagid). He was simultaneously Nagid of Granadan Jewry and a major Hebrew poet.
