The inauguration of the Malolos Constitution and the establishment of the First Philippine Republic represented a pivotal moment in the history of the Philippines. After centuries of Spanish colonial rule, the Filipino revolutionaries sought independence and self-determination. The Malolos Constitution, drafted by a revolutionary assembly, provided a framework for governance that drew inspiration from democratic principles. On this day, Emilio Aguinaldo, a prominent figure in the revolutionary movement, took the oath of office to become the republic's first president. The ceremony took place in the Barasoain Church in Malolos, symbolizing both the fervor of the revolutionary spirit and the establishment of a government formed by Filipinos for Filipinos. The constitution was notable for its affirmation of civil liberties, separation of powers, and the promise of accountability in governance.

During the ceremony, Aguinaldo emphasized the importance of unity and the collective effort required to safeguard the gains of the revolution. He called for cooperation among Filipinos to build a nation that would honor the sacrifices of those who fought for independence. The constitution marked a significant progress toward political self-assertiveness, providing the foundations for a legal and political framework that would guide the nation. However, the republic would face immediate challenges, including the transition from revolutionary government to a functioning state and the impending conflict with American forces, which would erupt later that year into the Philippine-American War.
