Muhammad ibn Yusuf ibn Nasr (Ibn al-Ahmar) was proclaimed emir at Arjona, marking the political emergence of the Nasrid leadership that would consolidate into the Emirate of Granada.
Muhammad I entered Granada and established it as the dynastic center; early defensive works on the Sabika hill initiated what became the Alhambra complex, the enduring architectural symbol of Nasrid rule.
The Treaty (Pact) of Jaén formalized a truce with Ferdinand III of Castile: Granada surrendered Jaén and accepted tributary/vassal-like obligations, a framework that helped the emirate survive amid Christian expansion.
As part of the post-Jaén political settlement, Muhammad I provided military assistance to Ferdinand III during the siege of Seville, underscoring Granada’s pragmatic diplomacy to preserve autonomy.
Castilian and Portuguese forces defeated the Marīnids (with Granadan participation) near Tarifa, blunting North African intervention in Iberia and reshaping Granada’s strategic environment on the Strait.
Alfonso XI opened a major land-and-sea siege of Algeciras, a key Strait port tied to Marinid power and Granadan security; the campaign drew in wider Mediterranean naval forces.
Algeciras surrendered to Castile, tightening Christian control of the Strait; a peace arrangement followed shortly after, altering Granada’s external alliances and frontier pressure.
During Yusuf I’s reign, major Alhambra expansion included construction of the Bab al-Sharia (now the Tower of Justice), strengthening the ceremonial and defensive entrance to the palatine city.
Under Muhammad V, construction began on the Court of the Lions palace—an architectural high point of Nasrid design that reflects Granada’s 14th-century cultural and artistic flowering.
Christian forces captured Alhama de Granada, an event widely treated as the opening of the Granada War (1482–1492), the final sustained campaign that ended Nasrid sovereignty.
Muhammad XII (Boabdil) besieged Lucena and was captured in the ensuing battle, intensifying internal Nasrid factional struggles and providing the Catholic Monarchs leverage in the war.
After a protracted siege, Málaga fell to the Catholic Monarchs, depriving Granada of its principal Mediterranean port and delivering a severe strategic and economic blow to the emirate.
The Treaty (Capitulations) of Granada was signed, setting terms for surrender and initially promising protections (including religious provisions) for the Muslim population upon transfer of sovereignty.
Muhammad XII surrendered Granada, ending the Nasrid Emirate and concluding the long Reconquista-era contest for territorial control in Iberia with Castilian annexation of the last Muslim-ruled state.
