The 19th century in Spain brought a bewildering period of instability, liberal revolutions, and conflict. During the early years of the 20th century, Spain was politically unstable, which resulted in a horrible civil war in 1936. These spectacular colorized photochroms show cities, streets, towns, landmarks, and everyday life of Spain in the late 19th century. These photos were colorized using the photochrom process. This process was invented in the 1880s by a Swiss printer. This technique was widely used to produce some of the earliest colorized pictures.
