How did Ranavalona I change Madagascar’s relationship with European powers?

Upon succeeding her husband, Radama I, in 1828, Ranavalona I fundamentally altered Madagascar’s relationship with European powers by reversing the previous policy of Europeanization.12

She actively sought to isolate the kingdom from foreign influence by expelling Christian missionaries and persecuting Malagasy converts. While she initially allowed a limited number of Europeans to remain for the purposes of external trade and local manufacture, she eventually expelled them as well. Her resistance to foreign encroachment was further demonstrated in 1845, when her forces successfully repulsed a joint British and French military expedition at Tamatave. By the time of her death in 1861, these policies had effectively isolated Madagascar from European influence.12
