How many countries in the world have capitals named after US Presidents?

The country that first springs to mind as having a capital that takes its name from a US President is of course, the USA itself, whose capital, Washington DC, honours the country's first President, George Washington (1732-1799).

However, Monrovia, the capital of the West African country of Liberia, is called after the 5th US President, James Monroe (1758-1831). Monroe was a prominent supporter of the founding of a colony of former slaves in Africa - the country itself takes its name from the word for "Liberty". When it was founded in 1822 it was the second country after Sierra Leone to be a permanent African-American settlement.

As recorded in the 2008 census, the city has a population of just over a million, comprising almost a third of the country's entire population.

Recently Monrovia has faced some trouble times, including civil war and the 2014 outbreak of Ebola.
