Ramon Castilla

Castilla fought as a junior officer in the decisive Battle of Ayacucho, which ended Spanish rule in Peru. This victory secured Peruvian independence and marked the end of the Spanish Empire in South America, shaping Castilla's nationalist views.

Castilla was elected President of Peru in 1845, serving until 1851. His first term focused on economic development, including the guano boom, and infrastructure projects such as railroads and ports, modernizing the Peruvian state.

During his second presidency, Castilla issued a decree abolishing slavery in Peru on December 3, 1854. This reform freed approximately 25,000 slaves and was part of a broader liberal agenda, though it faced opposition from slave-owning elites.

Castilla also abolished the indigenous tribute tax in 1854, which had been a burden on native communities since colonial times. This measure aimed to integrate indigenous peoples into the Peruvian state as equal citizens, though its implementation was uneven.

Castilla served a second term from 1855 to 1862, during the peak of the guano export boom. He used guano revenues to fund public works, pay off foreign debt, and modernize the military, but also faced criticism for corruption and over-reliance on a single resource.

Castilla oversaw the adoption of a new constitution in 1860, which established a centralized republic with a strong executive. The constitution remained in effect until 1920 and shaped Peru's political structure, though it limited regional autonomy.
