The first vestiges of near human accessions in Ondara are located in the caves of the Pigeon and of the Raven (average Paleolithic), cave oscuraoscura and in Segària's saw an Iberian settlement.
On the different theories that would explain the toponym Ondara, it seems to be that that of the teacher Manuel Sanchis Guarner is the most rigorous. According to him, he would proceed of "Undulating", Iberian word that means sandbank.
Special interest, they have for its proximity to the urban hull current and tied to the arrival of Roman colonists in Dénia, the appearance of several villas, necropolis and Roman ceramics in the items of the Plan of the Source, Raises and Vinyals, where numerous vestiges have recovered, the majority of they exposed in Dénia's Archaeological Museum, as well as several inscriptions honorific and undertaker's establishments recovered to the old town.
But, it will be under the Moslem domination when Ondara will have a great relevancy. With the protection of a small elevation and the water resource of the ravine of the Pond, there will be constructed a castle that will last for centuries, occupying the high part of the village, of which exponent stays the Tower of the Clock at the maximum. With the independence of the Caliphate of Cordova, 1012 Dénia's gang begins to form a part of the Kingdom.
There exists documentary verification of which Leader Warrior occupied temporarily the castle during the winter from 1090 to 1091, periode in that the castle would be re-strengthened, and from where it was required taxes from the king of Dénia. The Arabic domination in Ondara brought the expansion of the systems of irrigation, which still today last, an agrarian development and a growth of the important population.
Days after the conquest, the king Jaume I was in Ondara on June 6, 1244. It the first settlers met, though it was a opposite and unstable territory, a population for the most part Islamic. During this time, the people concerned so much to the kings as gentlemen individuals as Berenguer de Palau. In the year 1323 one gave for the king Jaume II, population and term, his son Pere, child of Aragon.
In 1472 they had news of an important activity in the cultivation of dry grape, realized by the Moriscos. At this moment, the population christens round 20 % of the total population, about 500 inhabitant. One of the most important surnames of the Catalan nobility, the Cardona, they will take charge of Ondara's dominion, where there will reside some of them as Antoni Cardona and Borja, Marquess of Guadalest, at the end of the 17th century.
At the begin of the 16th century, Ondara will be a stage of some warlike moments of the war of the slangs (1520-1523). There were Vicent Peris, leader of the movement of slangs, and the Marcas of Sup on You, I relate of Diego Hurtado of Mendoza, viceroy of Valencia, for another decree. Ondara was named in the 1544 Vicarious Perpetúa of Dénia's Marquisate and, the year 1574, the king Philip II gets from the Pope Gregori XIII the ascent of the vicarious one to Parish. Vila's title was granted in this time.
In 1609 it will suffer a big demographic bleeding with the expulsion of the Moriscos, approximately 895, which will make Ondara, in Escolano's words, firm and helpless. The repopulation began in 1611, with the arrival of Christian settlers from other villages of the region and of the Balearic Islands. With these there was implanted the Order of Paula's Sant Francesc, under the protection of You Mark of Guadalest, master of the village.
The 17th century will be a period of slow demographic and economic recovery, with some outbreaks of bubonic pest, up to assembling to the succession war, where the participation activates of Ondara in favour of the Archduke Carlos of Austria he supposed, after the defeat, a revenge for the Bourbon troops. Ondara was a burn and plundered. An illustrious ondarense, Joan Gil, was one of the popular figures of the popular movement austracista and antilordly.
During the war of the Frenchman (1808-1814), another son of Ondara, Diego Grustan, will be meant as Head of the guerrilla warfare opposite to the Napoleonic troops. The second half of the 19th century and with the cultivation of dry grape, Ondara will acquire a great relevancy in the region. The population grows, new streets are opened and numerous houses are built sumptuosas. This brilliance will finish with the epidemic, at the beginning of the 20th century, which will ruin the local economy and will push to hundreds of ondarenses to the emigration, (especially to Argentina and Algiers). Significant it is in this epoch, the presence of the Catalan doctor Jaume Ferran and Clua, inventor of the bovine antirage, which he applied in Ondara with notable success, whereas in other villages of the region, more sceptics, not to allow him to apply it, it cost them a considerable loss of human lives.
