Radama was assassinated on 12 May 1863. The new government under Queen Rasoherina and Prime Minister Rainivoninahitriniony sought to renegotiate the charter, leading to considerable friction between the "Companie de Madagascar" and the French government versus the Merina. It would still take three decades and several French interventions to make Madagascar a French colony. Breaking of the Lambert Charter was one of the pretenses for later French military involvement in the Franco-Hova war that led to the French conquest of the island.
