Rainivoninahitriniony's involvement in the
regicide plot had made him deeply unpopular among the people, and his excesses turned the opinion of many nobles against him. His fate was sealed during a visit to
Ambohimanga when, upon receiving the names of individuals accused of intentionally setting a series of house fires that had ravaged
Antananarivo, he sought to ensure the rapid arrest and execution of the accused conspirators.
Rasoherina opposed these executions, however, sparking Rainivoninahitriniony's anger and prompting him to declare violent threats to her sovereignty. Immediately afterward, Rasoherina set about to remove Rainivoninahitriniony from power with the support of Rainivoninahitriniony's younger brother
Rainilaiarivony, Commander-in-Chief of the army and influential leader among the
andriana. The queen addressed the public at Andohalo, first releasing
zebu into the crowd for public consumption in a bid to ensure popular approval of the transition, then announcing the deposition of Rainivoninahitriniony in favor of
Rainilaiarivony, relieving the Prime Minister of his post and stripping him of his ranks on July 14, 1864. In the final months of his life, Rainivoninahitriniony is believed to have participated in an attempted coup against the administration of his brother and the queen. On Friday, March 27, 1868, at two in the afternoon, a massive crowd armed with guns and swords attempted to storm the seat of government at the
Rova of Antananarivo in the interest of exerting control over the succession of the queen, who had been growing ever weaker from dysentery since October 1867. The leaders of the group successfully captured a number of key figures, including the head of the Queen's Guard. A group of guards, however, managed to escape and raced to notify Prime Minister
Rainilaiarivony, who was visiting the countryside estate where Queen
Rasoherina was convalescing. The Prime Minister gave the order to arrest the conspirators, several of whom were promptly captured upon the soldiers' return to the city. At five in the evening,
Rasoherina delivered a public address, asking those favorable to her rule to walk with her through the capital; a massive crowd paraded with her through the city, demonstrating their support for her continued authority. The queen then delivered a speech at Andohalo ordering the public to turn in any known conspirators to bring them to justice, before re-entering her residence at the
Rova to reassure the public with her presence. However, the windows along the route to the Rova were reportedly all ordered shut, whether to protect the Queen from projectiles or to keep the nobles of the upper town from viewing the advanced state of her infirmity. The physical and emotional exertion further weakened the queen, who died four days later, on April 1, 1868. Two main theories about the role of Rainivoninahitriniony in the coup against
Rasoherina were proposed although the truth was never confirmed. One theory offered that Rainivoninahitriniony had intended to establish a republic in Madagascar with himself as its president. An alternate and more probable theory maintained that Rainivoninahitriniony had formed an alliance with Protestant leaders who wished to see a male prince named Rasata placed on the throne. This prince would have been a puppet to Prime Minister Rainivoninahitriniony, who was committed to serving the interests of his Protestant allies. Rainivoninahitriniony died in exile in Ambohimandroso on 5 May 1868. ==References==
