In 1822, Brazil was on the cusp of transformation as tensions with Portugal escalated. The Portuguese Crown's attempts to reassert control over Brazil led to widespread discontent among the Brazilian elite and populace. On September 7, 1822, Pedro I, the Prince Regent of Brazil, famously declared 'Independência ou Morte!' ('Independence or Death!'), marking a decisive break from Portuguese rule. This declaration not only affirmed Brazil's autonomy but also set in motion a series of political developments that shaped its future governance.

Following independence, efforts to establish a new political order were underway. Pedro I's leadership was sought to stabilize the nation and build a unified government. The pro-independence leaders recognized Pedro as a strong figure capable of uniting the diverse factions within Brazilian society. On October 12, 1822, a formal ceremony was held in Rio de Janeiro in which Pedro was proclaimed the Emperor of Brazil, thus establishing a constitutional monarchy. His ascension to the throne was met with jubilation from supporters, who viewed him as a symbol of national unity.

This proclamation not only formalized Pedro's leadership but also established the framework for Brazil's governance under a constitutional monarchy. Within weeks, Pedro I would implement policies intended to promote Brazilian nationalism and autonomy, laying the groundwork for future developments in Latin America's history. This new structure would serve to balance traditional monarchy with emerging democratic ideals, a tension that would resonate throughout Brazil's later political landscape.
