Thousand Days' War
Between 1819 and 1849, there were no fundamental structural changes from the colonial period. By the mid-19th century, a series of fundamental reforms were enacted, some of the most important being slavery abolition and religious, teaching, print and speech industry and trade freedom, among others. During the decade of the 70s, radicalism accelerated reforms and state and social institutions were substantially modified. However, during the second half of the century, the country faced permanent pronouncements, declarations of rebellions between states, and factions which resulted in civil wars: the last and bloodiest was the Thousand Days' War from 1899 to 1902.
