Archaeology evolved from antiquarianism to a scientific discipline, influenced by the Enlightenment and scientific revolution. This shift brought systematic approaches to studying the past, with methods like stratigraphy and typology shaping archaeological interpretations. Key figures like Thomas Jefferson and Augustus Pitt Rivers pioneered excavation techniques, while others developed chronological systems. Theoretical frameworks emerged, from cultural-historical to processual and post-processual approaches, each shaping how archaeologists interpret the past.
