After a disputed election last month, the police and the armed forces eventually broke with the president and sided with protesters in demanding his resignation. Mr. Morales has insisted he is the victim of a coup.

Background: Mr. Morales, who came to power in 2006, stayed in the presidency longer than any other current head of state in Latin America. After leading Bolivia through an era of economic growth and shrinking inequality, he had pushed to change the law to run for a fourth term.

What’s next: An opposition lawmaker, Jeanine Añez, said that she would assume the interim presidency. But she would need a congressional quorum to approve a transfer of power, and Mr. Morales’s party, the Movement for Socialism, controls both houses of Congress.
