How did Gabriel Ramanantsoa's appointment end the First Republic?

The First Republic of Madagascar, led by President Philibert Tsiranana, faced significant instability following his reelection in January 1972. This period was marked by widespread political and labor unrest, which culminated in an uprising known as the May 1972 revolution.12

Faced with this social upheaval and his own declining health, Tsiranana appointed Maj. Gen. Gabriel Ramanantsoa as prime minister and granted him full powers of government. This appointment effectively signaled the end of the First Republic. Following this transition, a plebiscite held on October 8, 1972, confirmed Ramanantsoa as the head of government, and the office of the president was vacated when Tsiranana officially resigned on October 11, 1972.1234
