The history of Asunción is a vibrant chronicle of how a small fort established on a riverbank transformed into the "Mother of Cities" of South America and became the cradle of the distinct Paraguayan nation. Its past is inextricably linked to the Age of Discovery, colonial establishment, and the unique fusion of two cultures.
The city was founded by the Spanish conquistador Juan de Salazar y Espinoza on 15 August 1537. The date was not chosen by chance — on this day, Catholics celebrate the Feast of the Assumption of the Blessed Virgin Mary, known in Spanish as Asunción de María. Thus appeared the full name of the future city: Nuestra Señora Santa María de la Asunción, which over time was shortened to the concise "Asunción". Initially, it was merely a small military fort that Salazar founded after securing the support of the friendly local Guarani indigenous people. This alliance laid the foundation for the country's future cultural phenomenon.
Asunción owes its rapid rise to its strategically advantageous position on the banks of the deep Paraguay River, which served as the main transport artery on the route to the riches of Peru. When the first settlement of Buenos Aires was temporarily abandoned by colonists, many relocated to Asunción, which strengthened its status. The city quickly became the main administrative and political centre of a vast Spanish province. It was from here that expeditions were dispatched to found many other cities in Argentina, Bolivia, and Brazil, for which Asunción earned its honorary nickname, "The Mother of Cities".
From the very first days, the history of Asunción was shaped by the influence of two cultures — the European (Spanish) and the local (Guarani). Close interaction and intermarriages between colonists and indigenous people created the unique cultural code of modern Paraguay. This is directly reflected in bilingualism: both the Spanish language and the Guarani language still hold official status in the country. During the colonial period, the city's economy was focused on its administrative functions and servicing trade routes. Significant influence on the development of the city and the entire colony up until the 18th century was also exerted by the Jesuit order, whose missions became important cultural and economic centres of the region.
