Elizabeth II was the British sovereign who ruled longer than any other monarch in British history, making more than 80 state visits since 1952. Here are some of her most memorable encounters with Latin America:

1. A first visit to South America in Brazil

On Nov. 1, 1968, Queen Elizabeth II arrived in Recife, Brazil, on her first state visit to Latin America after being crowned in 1953.

The monarch landed accompanied by her husband, the Duke of Edinburgh, with whom she visited Salvador, Brasilia, São Paulo and Campinas before arriving in Rio de Janeiro.

In Brasilia, she was received by the then president, Marshal Artur da Costa e Silva. 

2. A trip to Panama 

After being crowned queen in 1953, the queen visited Panama for the first and only time on Nov. 29, 1953. 

Her passage through this country was part of her first international trip as monarch, since she had been crowned only six months earlier. 

3. Her visit to Mexico 

The first time Queen Elizabeth II came to Mexico was in 1975 to celebrate Flag Day in the capital's Zócalo.

The sovereign was the guest of honor of the then-president Luis Echeverría, who received her with mariachis during the gala dinner at the National Palace.

4. The Queen meets Juan Manuel Santos

Santos' visit to the U.K. was the only by a Colombian president, and came after he was awarded a Nobel Peace Prize for the treaty he struck with FARC, ending one of the world's longest armed conflicts.

Santos, president of Colombia from 2010 to 2018, was the first Colombian president to be invited with honors to U.K. by the Queen. 

He arrived at Buckingham Palace with First Lady Maria Clemencia Rodriguez de Santos. 

During his visit with the Queen, the former president highlighted the Queen's support for the Peace Process and all the contributions offered to establish the dialogues with former FARC guerrillas.
