(CNN) — Dina Boluarte took office as the new President of Peru on Wednesday, after Congress ousted former president Pedro Castillo.

In this turbulent context, Boluarte, who until a few hours ago was the country's Vice President, took over as Castillo's successor after being sworn in before the plenary session of Congress on Wednesday afternoon.

She is the first female president in Peru's history, and the sixth Peruvian president in less than five years.

Peru has a female president for the first time, after ex-president Pedro Castillo was impeached - hours after he tried to dissolve parliament.

Dina Boluarte - previously the vice-president - was sworn in after a dramatic day in Lima on Wednesday.

Earlier in the day, Mr Castillo had said he was replacing Congress with an "exceptional emergency government".

The former culture minister replaces Aníbal Torres, who resigned after losing the confidence of the Andean parliament.

Peruvian President Pedro Castillo accepted the resignation of his prime minister Wednesday and replaced him with a female environmental activist.

Under Peruvian law, the prime minister's resignation automatically triggered that of the entire cabinet.
