Archaeological remains from the Bronze Age have been found , while important Roman artefacts have been emerging in the country estates in Ponce, Las Lumbreras and La Ballestera. Periods later, Montellano acquired great strategic importance with Cote Castle. This important building was on the first defensive line on the Christian-Nazarite border and formed a powerful triangle that defended access across the Guadalete River.
After the War of Granada and during the 16th and 17th centuries, a few small settlements sprang up around Cote Castle, dependent on the Duke of Osuna and under the jurisdiction of Morón de la Frontera. Carlos III awarded it villa status in 1788.
During the War of Independence, the town was burned down by French troops.
