The first evidence of human occupation in Lloseta, as in the other municipalities of the island, dates from the pre-Talaiotic and Talaiotic periods. The excavation campaigns conducted in the 1960s have helped us gain a more precise knowledge about our ancestors. Lloseta has five archaeological sites, comprising four burial caves and a fortified area.
There is very little proof of the presence of the Roman civilization in Lloseta. Apart from the possible Roman etymological origin of the name “Lloseta”, which is supported by several historians, only a few casual findings have documented the presence of Roman settlements in the area.
If the historic evidence of the Roman period is limited, evidence of the period stretching from the 5th to the 10th century is non-existent or at least unknown. Nothing is known about the presence of the Vandals and Byzantines, which confirms the expression “dark centuries”, which has been applied so often to the history of Mallorca, for this period.
There is also very little proof of the Muslim period, which lasted two centuries. The only evidence is the inclusion of Lloseta in the administrative district of Canarossa, which also included the municipalities of Binissalem, Sencelles, Costitx, Alaró, Santa Eugenia, Consell and Santa Maria, and the conservation of several place names such as es Morull or sa Cova des Moros, which reminds us of the presence of Muslim communities.
The light of history returned to Lloseta with the Catalan Conquest led by King Jaume I. The land was divided between the conquerors and the Muslim area of Canarossa was awarded to Guillem de Montcada, the Viscount of Bearn, who apportioned the land between his knights. It is extremely difficult to estimate the population of Lloseta during this period, since there was no register of population. Population estimates can be established based on tax sources. A further problem is that during this period the towns of Lloseta and Aiamans were part of Binissalem.
From a socioeconomic point of view, the 16th century was marked by the introduction of land registry, which helps researchers have a better understanding of the socioeconomic reality of the Mallorcan towns. Based on the land registry of 1578, researchers concluded that in Lloseta and Aiamans there were three estates -Lloseta, Son Pelai i s'Estorell-, a knightly estate owned by Lluís Togores and 80 properties consisiting of house and land. The Baile, Martí, Prats, Miquel and Ramon de Son Ramon were the most powerful families.
In the 17th century the population showed a slight increase according to the study of the three land registries of 1688 and 1697 conducted by Jaume Capó. The first registry records a population of 240 inhabitants. 20 years later the population totalled 305 and 300 inhabitants at the end of the 17th century.
Lloseta and the Kingdom of Mallorca as a whole played an important role in the Spanish War of Succession. On the one hand, Miquel Joan Ballester, Count of Aiamans, played an active part on the Bourbon side. He took part in the conspiracy in favour of King Felipe V in 1711, as did the Sales family, owners of Son Pelai. On the other hand, 20 men of Lloseta, together with men from Binissalem, took part in the defence of the coast of sa Porrassa and Santa Ponça, in anticipation of the disembarkment of the troops of King Felipe V. With the establishment of the Bourbon administration, the Counts of Aiamans held a significant position as councillors of the Palma Town Hall, which was created in 1718.
In the 19th century Lloseta achieved municipal autonomy. It split from Binissalem between 1812 and 1814. Llorenç Català was the first constitutional mayor of Lloseta.
As an autonomous municipality, Lloseta experienced the rise of the workers’ movement. During the 2nd Spanish Republic the rightwing parties dominated the elections, even though the Town Council elected in 1931 was abolished by the civil government by request of a group of people of Lloseta.
Nine “Llosetins” died in the Spanish Civil War. Militias were organized in Lloseta and they decided to appoint Abdon Homar secretary of the Town Hall. Furthermore, a new governing commission led by the Falangist Joan Mut Jaume was appointed.
The municipality underwent a profound transformation in the last decades of the 20th century. In the field of demography, migration has caused a constant growth in population to 4,500 inhabitants. The demographic growth brought with it urban development which has changed the appearance of the former lands of Son Togores, ses Flexes, etc. Blocks of flats have replaced the fields of almond and fig trees and have given the municipality of Lloseta its present modern appearance.
