Valanchery, which was a part of the erstwhile princely state of the Valluvanad in the early medieval period, had been under the direct control of the Zamorin of Calicut following the Tirunavaya war of 14th century CE.

Valanchery was originally part of the Valluvanad Swaroopam dynasty in the early medieval period (12th century CE).

[5] On the west, it was bounded by the Arabian Sea at Ponnani and on the east by the Attappadi Hills during their zenith in the early Middle Ages.

[5] According to local legends, the last Cheraman Perumal ruler gave a vast extension of land in South Malabar during his journey to Mecca to one of their governors, Valluvakonathiri, and left for pilgrimage.

Assisted by the warriors of their subordinate chiefs (Chaliyam, Beypore, Tanur and Kodungallur) and the Muslim naval fleet under the Koya of Kozhikode, the Samoothiri's fighters advanced by both land and sea.

The Kizhakke Kovilakam Munalappadu, who took a leading part in this campaign, received half of the newly captured province from Samoothiri as a gift.

Under the British Raj, Valanchery was an Amsom included in Cheranad which was scattered in the Taluks of Eranad and Ponnani in the erstwhile Malabar District.

[7] The pottery industry and the blacksmith community, which has adopted it as a traditional caste occupation, were a part of Valanchery's identity.

In 1932, as a part of the freedom struggle, a favorable environment was created for the seeds of a national political outlook to germinate in Valanchery.

[8] After the Guruvayur Temple Satyagraha and Kelappan's fast, a referendum was held to get the views of the upper caste Hindus of Ponnani taluk.

[8] It was on this occasion that prominent national leaders including Kasturba Gandhi, C. R. Das's sister Urmila Devi, Sadashiva Rao, C. Rajagopalachari, and U. Gopala Menon, visited Valanchery.

[8] As a result of the efforts of Mazhuvanchery Damodaran Namboothiri and others, a united currency group (Aikya Nanaya Sangham) had functioned in Valanchery.
