Melilla Day is observed in the autonomous city of Melilla, Spain, every September 17. This regional holiday commemorates the anniversary of the Spanish conquest of Melilla in 1497, which occurred shortly after the Reconquista, a period marked by the Christian kingdoms reclaiming territories from Muslim rule. The city was captured with little resistance under the leadership of Pedro Estopiñán, following an agreement with Portugal that allowed the Spanish to seize the area. While Melilla Day is an official public holiday celebrated with various festive events and activities, it is important to note that some residents protest the holiday, advocating for Melilla's independence from Spain and its integration into Morocco. The holiday reflects the complex historical and cultural dynamics of the region.
