The events of recent days in Malaysia have been dizzying.
A former prime minister, Mahathir Mohamad, 92, returned to power last week after a stunning upset vote, defeating not just his former protégé, but the very party he helped create.

Here is our guide to the people and events that led to Mr. Mahathir’s return to power and Mr. Najib’s fall from grace.
