Political map of North America & the Caribbean 14 April 1907 (Nicaragua-Honduras War): Central American instability came to a head in 1907, when Nicaragua invaded and occupied Honduras (Honduran Civil War (1906–1907)). Fed up with the endless conflict in the region, the US stepped in, pushing the five independent Central American states to agree to a peace conference (Central American Peace Conference of 1907) and establish a Court of Justice to resolve future disputes (Central American Court of Justice).
