Premise: Central America . After New Spain achieved independence from Spain in 1821 , some of its provinces were annexed to the First Mexican Empire , but soon seceded from Mexico to form the Federal Republic of Central America , which lasted from 1823 to 1838 . The seven states finally became independent autonomous states : beginning with Nicaragua , Honduras , Costa Rica , and Guatemala ( 1838 ) ; followed by El Salvador ( 1841 ) ; then Panama ( 1903 ) ; and finally Belize ( 1981 ) .
Hypothesis: Central America only contains non-sovereign states.
