Under the leadership of Gjergj Kastrioti, widely known as Skanderbeg, the Albanian forces launched a strategic assault on Kruja, a key fortification that held strategic value against the advancing Ottoman Empire. Skanderbeg, who had previously been a knight in the service of the Ottoman Sultan, turned against his former masters and forged an alliance of local lords and soldiers. This coalition was critical in the effort to reclaim territory occupied by the Ottomans. As the forces breached the defensive walls of Kruja, they encountered fierce resistance but ultimately prevailed, leading to the liberation of the city. The raising of the Albanian flag was not just a symbolic act; it represented a unifying moment for the Albanian people and a clear declaration of their intent to resist foreign domination.

Following the liberation, Skanderbeg established a defensive stronghold in Kruja, which became the center of Albanian resistance against Ottoman rule for over two decades. The town was strategically chosen, given its mountainous terrain, which provided natural defenses. Skanderbeg’s successful liberation of Kruja attracted attention across Europe, inspiring other Balkan leaders to consider resistance against Ottoman advances, thereby increasing the momentum for a broader Balkan uprising. His guerilla tactics, combined with his deep understanding of local politics, allowed him to sustain resistance despite being vastly outnumbered.

The political atmosphere in the region was shifting as Skanderbeg sought to create a unified Albanian state, garnering support from various feudal chiefs. His charisma and leadership ability were instrumental in rallying not just warriors but also civilians who saw in him a champion of their cause. The event served as a catalyst for other uprisings in Albania and the surrounding regions, marking the beginning of a prolonged struggle that would last for years to come, making Skanderbeg a lasting symbol of Albanian identity.
