In a country where the vast majority of citizens consider themselves Christian, said Mr. Corrales, the analyst, Ms. Añez has turned to Bolivia’s conservative religious groups for support to mask her lack of a popular mandate.

Ms. Añez’s close ally, Luis Fernando Camacho, on Wednesday held a political rally at which another speaker shouted disparaging references to the Indigenous culture that Mr. Morales championed: “We have tied all the demons of the witchery and thrust them into the abyss. Satans, get out of Bolivia now.”

Ms. Añez’s revival of Catholic rituals in public events has caused more than a little discomfort because the Constitution defines Bolivia as a secular state. Her religious zeal has also caused concern among some Indigenous groups who associate Catholicism in politics with the former conservative governments that had long treated them as second-class citizens.

In a further shift from Mr. Morales’s focus on Indigenous rights, Ms. Añez has filled her cabinet with politicians from the country’s eastern lowlands, which are dominated by Bolivians of mixed or European descent. Many of her ministers have been staunch opponents of Mr. Morales’s socialist policies or have served in previous conservative administrations.

The most radical changes have come from the Foreign Ministry. In just a few days, Ms. Añez, has cut Mr. Morales’s alliances with leftist governments in the region. She broke off relations with President Nicolas Maduro of Venezuela and kicked out hundreds of Cuban doctors working in the country.
