The Spanish Liberal Revolution refers to a series of political and social changes in Spain during the early 19th century, primarily between 1808 and 1874. It aimed to establish a constitutional government and limit the power of the monarchy. Key events included the adoption of the Cadiz Constitution in 1812, which promoted individual rights and representative government. The revolution was marked by conflicts between liberals, who sought reforms, and absolutists, who wanted to maintain traditional monarchy. This struggle led to various uprisings and changes in leadership, ultimately shaping modern Spanish politics and society.
