The letter of Foundation of Segura, signed by Alfonso X, was also an act of repopulation: all the inhabitants were legally free.
Advantages of being a village: commercial privilege, lack of tolls and taxes.
The letter of Foundation of King Alfonso X granted certain privileges to the Villa of Segura: all the inhabitants were legally free. In addition to being assured of defense and justice, each citizen had freedom of purchase and sale (freedom of trade), and this meant that each citizen could freely dispose their goods, in addition to not having to pay taxes and tributes.
Those who participated in the Fueros of Vitoria (was the case of Segura) did not have to pay taxes in all Kingdom of Castile.
Local residents also had other rights, such as;
-Immunity for the judget in exchange for a deposit.
-Right to elect the Mayor.
-Right to not do the military service.
The composition of the society:
In terms of the composition of society, social groups of the city were divided as follows:
1. Lords, knights and squires. This was the group of people that were free of taxes. They were people with privileges and they often took different positions in the local government.
2. The farmers: this was the largest group and and they were forced to pay taxes.
Later, as the village was developing, other type of groups began to appear such as merchants, artisans, and lawyers.
The smallest group of inhabitants was composed of clergy.
These groups were associations of people that worked in the same sector and were founded to defend the rights of the workers.
Similar to guilds of trade, fraternities were associations of people who were involved in the religion. They usually had the name of a saint and organized acts and processions in his honor.
