The golden age of the Merina civilization gave way, inevitably, to an era of challenge and upheaval. The latter half of the nineteenth century saw the kingdom beset by a convergence of internal discord and external threats, each compounding the other and eroding the foundations so carefully laid by generations past.

Within the royal court, succession crises and factional intrigue became endemic. The death of Radama II in 1863, under circumstances that contemporary accounts describe as both sudden and suspicious, triggered a period of political instability. Competing factions vied for influence over the monarch, and the authority of the sovereign was increasingly contested by powerful ministers and military leaders. Inscriptions and chronicles from this era grow terse and ambiguous, hinting at the violence and uncertainty that stalked the palace halls. Archaeological research into the remains of the Rova of Antananarivo reveals hurried modifications to defensive structures and changes in palace layout, suggesting heightened anxieties and the need for greater internal security. Evidence of burned timber and hastily repaired stonework points to episodes of violence and unrest that periodically erupted within the royal precincts.

Religious tensions flared as the Christian faith, introduced decades earlier, gained new adherents among both commoners and the elite. The monarchy’s oscillation between persecution and tolerance left communities divided, and reports indicate that covert worship, denunciations, and purges became part of the social fabric. The old rituals persisted, but now in the shadow of new churches and the ominous presence of foreign missionaries. Descriptions from European missionaries and Malagasy chroniclers alike record the competing rhythms of cathedral bells and ancestral drumbeats echoing through the capital. Archaeological surveys of Antananarivo and its surrounding villages have uncovered the foundations of early stone churches positioned close to traditional wooden zoma market squares, providing tangible evidence of the uneasy coexistence and, at times, confrontation between imported and indigenous faiths.

Economically, the Merina kingdom faced mounting difficulties. Prolonged periods of drought and locust infestations, documented in both oral histories and colonial records, decimated rice harvests and strained the kingdom’s ability to feed its population. Terraced paddies, once green and abundant on the highland slopes, fell fallow or yielded only meager returns. Contemporary accounts describe how granaries, typically overflowing after the harvest season, stood half-empty. Tax burdens grew heavier as the state struggled to maintain its armies and bureaucracy, with evidence from surviving tax records indicating an expansion in both the range and severity of levies imposed on villages and urban districts. The expansion of the global economy and the arrival of European traders and colonial agents further disrupted traditional markets, introducing new goods—textiles, firearms, and imported alcohol—but also new dependencies that undermined established craft industries and barter networks. Archaeological finds of imported ceramics and European glassware, mixed among local pottery shards, speak to the complex entanglement of foreign and Malagasy material culture during this era.

The external pressures facing the Merina were no less formidable. French and British ambitions in the Indian Ocean intensified, with both powers seeking to extend their influence over Madagascar. Treaties, often signed under duress or in conditions of ambiguity, ceded economic and diplomatic privileges to the Europeans. The pattern that emerges is one of incremental encroachment: first advisors, then soldiers, then outright demands for territorial control. Surviving treaty documents, many now preserved in European archives, bear witness to the gradual erosion of Merina sovereignty, with concessions extracted over customs, trade, and even the conduct of justice in the capital.

Military resistance proved costly. The Merina army, once the terror of the highlands, struggled to match the firepower and discipline of European forces. The Franco-Hova Wars of the 1880s and 1890s, vividly documented in French military archives, saw the kingdom’s defenses breached, its fortresses bombarded, and its soldiers overwhelmed. Archaeological surveys of former battlefield sites around Antananarivo and in the central highlands have uncovered spent bullets, fragments of artillery shells, and the shattered remains of defensive earthworks, testifying to the intensity of the conflict. The capital itself became a city under siege, its inhabitants enduring bombardment, disease, and privation. Contemporary reports describe neighborhoods reduced to rubble, the air thick with woodsmoke, and streams of refugees seeking shelter within the palace enclosure or fleeing into the hills.

Social unrest simmered as the burdens of war and occupation grew. Accounts from the period describe villages emptied by conscription, fields left untended, and a pervasive sense of uncertainty. The traditional hierarchies that had defined Merina society for centuries began to fray, with local leaders asserting autonomy and the authority of the monarchy waning. Archaeological evidence from rural sites documents a decline in the construction of monumental tombs and communal granaries during this period, indicating both demographic stress and the weakening of collective social structures. Oral traditions record memories of displacement and dislocation, as families were uprooted and communities fragmented.

The final blow came in 1897, when the French formally abolished the Merina monarchy and exiled Queen Ranavalona III to Algeria. The royal palaces were looted, sacred tombs desecrated, and the kingdom’s administrative structures dismantled. The sounds of Antananarivo changed—from the chants of royal ceremonies to the barked orders of colonial officials. Surviving architectural surveys reveal how European-style buildings and military installations supplanted traditional wooden structures, while the grand processional avenues of the capital were repurposed for colonial administration. The Merina civilization, as it had existed for centuries, was brought to an abrupt and painful end. Yet, even in defeat, echoes of its greatness lingered in the hills, the language, and the memories of its people. The legacy of the Merina would not vanish, but would instead find new forms in the era that followed.
