In short
On January 2, 1492, the last Muslim kingdom in Western Europe surrendered to Spanish Christian monarchs Ferdinand and Isabella. The fall of Granada ended nearly 800 years of Islamic rule in Iberia and gave Spain the momentum to become a unified, global power-the same year Columbus sailed across the Atlantic under their flag.

Timeline
How it actually unfolded.
Marriage of Ferdinand and Isabella
Ferdinand of Aragon and Isabella of Castile marry, uniting the two largest Christian kingdoms in Iberia and creating the foundation for a consolidated Spanish state capable of conquering Granada.
Granada War begins
The decade-long conflict begins, driven by internal divisions within the Nasrid dynasty. Boabdil and his father Abu al-Hasan compete for control of the emirate while Ferdinand and Isabella exploit the discord.
Siege of Málaga
One of the war's bloodiest episodes; the Christian forces under Ferdinand and Isabella besiege the coastal city for four months. After Málaga falls, most defenders are enslaved or executed, shocking the remaining Muslim cities into recognizing Granada's isolation.
Siege of Granada begins
Ferdinand positions forces around Granada city itself, establishing a blockade that cuts supply lines and forces negotiations. The siege lasts until Boabdil's surrender.
Treaty of Granada signed
Boabdil and Ferdinand sign preliminary peace terms guaranteeing Muslims the right to remain, practice Islam, and keep their property. The treaty formalizes the end of hostilities but leaves details of transition unresolved.
Boabdil surrenders Granada
The last emir of Granada formally hands over the Alhambra and the city to Ferdinand and Isabella. Spanish forces enter Granada; the Reconquista is officially complete.
Alhambra Decree issued
Isabella and Ferdinand issue an edict expelling all Jews from Spain within four months. The decree applies to those who refuse conversion to Christianity, mirroring the pressure already placed on Muslim populations.
Columbus reaches the Caribbean
Columbus, sailing under the flag and patronage of Ferdinand and Isabella, reaches the Caribbean. The expedition departs just months after Granada's fall, launching Spain's age of Atlantic exploration.
Muslim conversion crisis escalates
Forced conversions intensify in Granada. Archbishop Talavera's early promises of tolerance collapse as Isabella pushes for rapid Christianization, provoking resistance and an uprising in the Alpujarra mountains.
Conversion deadline moved forward
The expulsion deadline for non-converted Muslims is accelerated from 1500 to 1502. Those refusing conversion face exile; most are expelled to North Africa.

Gregorian chant and liturgical music - Cathedral choirs of Spain
Religious music dominated courtly and ecclesiastical life; the victory was celebrated through sacred compositions commemorating Christian triumph.
Same week, elsewhere
In 1492, Granada's fall was celebrated across Christian Europe as a triumphant recovery of lost Christian lands. The victory reinforced the ideology of religious holy war (crusade) that had defined the Reconquista, while simultaneously unsettling the delicate coexistence of Muslims, Christians, and Jews that had characterized medieval Iberia. The conquest coincided with the age of European exploration and the dawn of the Atlantic world.

Istanbul's Conquest by Ottomans
Both Granada (1492) and Constantinople (1453) represent the final expulsion of non-Muslim powers from territories they had held for centuries; Granada's fall completed the Christian Reconquista of Iberia while Constantinople's fall secured Ottoman Islamic hegemony over the eastern Mediterranean-mirror processes in the same geopolitical era.
Unification of Italy
Both Granada's completion of the Reconquista and Italian unification represent the 15th–19th century trend of religious and territorial consolidation that reshaped European nation-states.
