Yusuf III (July 16, 1376 – November 9, 1417) was the thirteenth Nasrid ruler of the Emirate of Granada from 1408 to 1417.
He was initially designated heir to the throne by his father, Yusuf II. His succession was thwarted when his half-brother Muhammad VII seized power in 1392 and confined him for more than fifteen years in the castle of Salobreña. During this long imprisonment, Yusuf devoted himself to scholarship and poetry. Upon the death of Muhammad VII in 1408, he was released and proclaimed emir under the regnal title al-Nasir li-Din Allah. Once on the throne, he relied on the support of his powerful chamberlain Abu l-Surur Mufarrij and quickly moved to stabilize the political situation he had inherited.
Yusuf III's reign was characterized by diplomatic pragmatism, intermittent military conflict, and cultural flourishing at the Nasrid court. Although he suffered a major setback with the loss of the strategic city of Antequera to Castile in 1410, he succeeded in negotiating a series of truces with Castile and Aragon that ensured relative stability along the frontier for much of his rule and even beyond his death. At the same time, he confronted challenges in North Africa, most notably the rebellion of the Marinid garrison of Gibraltar, which he eventually recovered in 1414 after a prolonged siege. A cultivated ruler and accomplished poet, Yusuf fostered an active literary circle at the Alhambra and composed a substantial body of poetry. Despite recurring illness and personal tragedies within his family, he governed for nearly a decade and died in 1417 at the age of forty-one, leaving a kingdom that, despite recent territorial losses, enjoyed a measure of internal stability and diplomatic balance.

Early life
Yusuf was born on July 16, 1376, during the height of the Nasrid dynasty under the reign of his grandfather Muhammad V. His early life was spent in an environment of courtly magnificence and intellectual vitality.
Yusuf was the eldest of five brothers and had one sister, Umm al-Fath, whose judgment he later respected deeply. His father, Yusuf II, designated him heir apparent upon his accession in 1391. His status as the eldest son and his intellectual promise strengthened this choice. However, his half-brother, Abu ʿAbd Allah Muhammad (later Muhammad VII), resented the succession arrangement and unsuccessfully rebelled against their father. Shortly afterward, Yusuf II died suddenly, possibly by poisoning, and Muhammad VII seized the throne in 1392, displacing the legitimate heir.
Upon his brother's accession, Yusuf's fortunes changed dramatically. He was removed from his position as crown prince and confined in the coastal castle of Salobreña, a Nasrid residence and fortress that also functioned as a prison for high-ranking captives. There he spent almost sixteen years in confinement. His imprisonment was intended to eliminate any potential dynastic challenge to Muhammad VII. The years of isolation profoundly shaped him. During this prolonged captivity he devoted himself to poetry and intellectual pursuits, producing literary works that reflected longing for Granada, grief for his father, indignation at injustice, and meditations on fate and divine will.
Reign (1408–1417)
His liberation came unexpectedly in 1408 when Muhammad VII died, possibly from poison. Christian sources recount that the ruling emir had ordered Yusuf's execution on his deathbed to secure succession for his own son, but his execution was delayed long enough to allow Yusuf's supporters to liberate him. Whether or not the anecdote is accurate, Muhammad VII's death enabled Yusuf's supporters to proclaim him emir. The architect of his release was the powerful official Abu l-Surur Mufarrij, a freedman of Christian origin who soon became his principal adviser. On May 13, 1408, at nearly thirty-two years of age, Yusuf III was proclaimed emir and adopted the laqab al-Nasir li-Din Allah (“Defender of the Religion of God”).
Yusuf III's accession required swift consolidation. He appointed Abu l-Surur Mufarrij as hajib (grand vizier) and cemented ties by marrying his vizier's daughters. His reign began under delicate circumstances, as frontier tensions with Castile were acute and internal loyalties uncertain. Nonetheless, he adopted a conciliatory stance, refraining from reprisals against those who had supported his brother and even extending favor to Muhammad VII's children. Both Muslim and Castilian sources portray him as prudent, gentle, and inclined toward peace.
His reign initially focused on diplomacy. Within days of his accession, he notified the Castilian authorities of the change in rule and sought to continue the existing truces. Through skilled negotiation, truces were renewed and extended multiple times between 1408 and 1410. Although frontier incidents persisted, these were generally contained. His diplomatic efforts produced a pattern of renewable truces that stabilized relations with Castile for most of his reign and, significantly, continued beyond his death.
Peace, however, was interrupted by a major Castilian offensive culminating in the siege of Antequera in 1410. Anticipating conflict, Yusuf III ordered preemptive raids, including attacks from Ronda against Zahara de la Sierra and other frontier positions. Meanwhile, the Castilian regent Ferdinand (later Ferdinand I of Aragon) laid siege to Antequera in April 1410 with extensive resources. Yusuf concentrated Granadan forces near Archidona under the command of his brothers Abu l-hasan Ali and Abu l-Abbas Ahmad. An engagement on May 6, 1410, ended in defeat for the Nasrids. Despite determined resistance, including heroic action by the jurist Ibn asim, the city ultimately fell after a five-month siege. The loss of Antequera in September 1410 was a significant blow, depriving Granada of a key defensive stronghold that controlled key approaches to Málaga.
Family
Yusuf's family life was marked by tragedy. Shortly after his accession he married, but his first wife and their infant son died soon after childbirth. Subsequent marriages produced several children, including Muhammad VIII, who would succeed him. He also experienced the loss of another son during a plague. A serious personal and political loss was the death of his brother and principal military lieutenant, Abu l-hasan Ali in 1416. The emir mourned him deeply; the prince had played a central role in frontier defense and state stability.
Poetry
Yusuf was a cultured man, and his literary talent and poetry were notable. He is considered to be among the best Andalusian poets of the 15th century, along with Ibn Furkun and al-Basti. After his release from prison, he created a large and prolific literary court in the Alhambra. Numerous poems were dedicated to him, both by his official poet and private secretary, Ibn Furkun, and by more than a dozen other authors.
The poems composed by Yusuf III formed a large collection, that was published twice in the 20th century. In addition, Yusuf III is the author of a book dedicated to the life and work of the prime minister Ibn Zamrak, who served his grandfather Muhammad V, his father Yusuf II and his brother Muhammad VII.
