On March 22, 1387, Jogaila, Grand Duke of Lithuania and King of Poland, granted a city charter to Vilnius, the capital of Lithuania, allowing it to be self-governing and establishing its status as a major urban center in Eastern Europe. The charter was part of Jogaila's broader efforts to consolidate his authority and promote the Christianization of Lithuania. The granting of the charter marked a significant step in the development of Vilnius as a political, cultural, and economic hub.

The granting of the city charter to Vilnius was commemorated in Lithuanian chronicles and poetry, which celebrated the city's new status as a center of culture and commerce. The event also contributed to the development of Lithuanian literature, as the city became a hub for the production of religious and secular texts in both Latin and the vernacular. The city's status as a center of learning and culture would later be celebrated by Polish-Lithuanian poets, including Adam Mickiewicz, who wrote extensively about Vilnius in his works.
