The Democratic Progressive Party (Partido Demócrata Progresista, PDP) was founded at a meeting in the luxurious Hotel Savoy in Buenos Aires, led by Lisandro de la Torre, a prominent political figure and reformist. The establishment of the PDP came in response to the political climate of early 20th-century Argentina, characterized by a rising demand for progressive reforms amid increasing social inequality and political corruption. At this historic gathering, de la Torre and fellow reformists sought to create a political platform that would prioritize social welfare, democratic governance, and transparency in politics, appealing particularly to the burgeoning middle class and intellectual circles disillusioned with the existing systems.

The party's founding represented a significant shift in Argentine politics, as it aimed to break away from the entrenched political systems dominated by oligarchic interests. The founders believed that by advocating for social reform and engaging actively with citizens, the PDP could inspire a movement towards a more equitable and just society. The discussions held in the Hotel Savoy included strategies to address pressing national issues, which were increasingly giving rise to public discontent. Themes of accountability, civil rights, and economic cooperation were central to their platform, reflecting broader international trends of the time, as many nations faced similar challenges of modernization and social change.

The PDP would go on to play a crucial role in Argentine politics in the coming decades, influencing legacies and shifting political alignments. As the party positioned itself as a modern alternative to traditional political organizations, it attracted a significant following among the youth and intellectuals who were eager for change. The founding meeting marked not only the beginning of the PDP but also illustrated the desires of a segment of society for progressive political representation, thus suggesting a new era in Argentine political discourse and activism.
