Archaeological remains have been found from the Bronze Age, while important Roman artefacts have emerged in the country estates in Ponce, Las Lumbreras and La Ballestera. In later periods, Montellano acquired great strategic importance through Cote Castle. This important location 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, dependents 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.
Holy Week (Easter). Highlights are:
- La Borriquita, Palm Sunday.
- El Cristo del Gran Poder (Virgen de los Dolores), Holy Wednesday.
- El Cristo de los Remedios (Virgen de la Amargura), Good Friday.
- Los Jubileos. Local festivity celebrated for four days in honour of Nuestra Señora de los Ángeles. It takes place on the dates next to the 2 August.
- Romería de San Isidro Labrador. Held on the first Sunday after 15 May, the Patron Saint Festival is without doubt the most popular and well-known celebration in Montellano. This romería (procession) is one of the most traditional and prestigious events of the many celebrated in Andalusia. It has been declared an Andalusian Fiesta of National Tourist Interest. Its merry character and the local hospitality have most certainly contributed greatly to this.
- Feria Agroturística y Ganadera (Agro-tourism and Livestock Fair). Held in early May, this event tries to recapture the essence of old livestock fairs.
- Flamenco Festival of un-established artists. This is organised by the flamenco group El Madroñero de Montellano. It is held on the Saturday before Los Jubileos
