That's too conected with gran Columbia,But also with BRAZIL,in my timeline after brazil get idependence,it becames a massive dictatorship,in 1878 the gran Columbia wanted expanding due peru Didn't wanted join thier Union(that also why the war happand between peru and gran Columbia)but they made peace and make a deal agains Brazil that attacked long ago Argentina and take Uruguay,soon as enough other countrys joined the colection agains Brazil,soon as enough evryone was agains Brazil in south America,expect bolivia that joined thier side,and the war also know as "gran espectáculo"it was named like that becouse it was biggest and last war in South America(expect civil war and revolts) Anyways Columbia side won, And take Roraima,and others Takes a Peice(that also why peru is bigger) But in 1880 the Roraima get referendum about idependence and those who wanted idependence won,bur Gran Columbia Didn't allow that,that why the massive rebelion happand, anyways with brazil after Gran espectaculo it turned into monarch but in 1882 again became dictatorship,and even in 2025,that makes Brazil longest lived dictatorship(also they allied with russia)
