Empire of Brazil

The Empire of Brazil was the constitutional monarchy that governed Brazil for most of the nineteenth century, the only enduring monarchy to emerge in the Americas after the wave of independence movements.

It was established in 1822 when Pedro, the son of the Portuguese king and regent of Brazil, declared the country's independence from Portugal and was acclaimed Emperor Pedro I. Unlike the Spanish American colonies, which fragmented into numerous republics often amid prolonged warfare, Brazil achieved independence with relative continuity and remained territorially united under a single monarch. Pedro I granted a constitution in 1824 that created a centralised parliamentary monarchy with a distinctive 'moderating power' vested in the emperor. After a turbulent reign, Pedro I abdicated in 1831 in favour of his young son, leading to a difficult regency period marked by regional revolts. The empire reached stability and prominence under Pedro II, who ruled for nearly half a century and presided over a long era of relative political stability, economic growth driven especially by coffee exports, the expansion of railways and infrastructure, and a flourishing of the arts and sciences. Brazil under Pedro II also emerged as a leading South American power, notably through its decisive role in the Paraguayan War (1864–1870). The empire's economy and society, however, remained deeply dependent on slavery, and the long struggle over abolition was central to its later politics. The gradual end of slavery, culminating in complete abolition in 1888, alienated the powerful landowning elite, while the military and republican movements grew increasingly assertive. In November 1889 a military coup, supported by republican and positivist groups, overthrew Pedro II and proclaimed a republic, ending the Brazilian monarchy and inaugurating the First Brazilian Republic.
