Alguacil (in Spanish), Aguazil or Guazil (in Portuguese) is a title often to be encountered in stories and plays, derived from the Arabic "وزير (wazir)", meaning "minister", preceded by the article "al".
The Alguacil among the early Spaniards was a judge, and sometimes the governor of a town or fortress, or the master at arms on a vessel. In later times the office was gradually lowered to the rank of an officer of the court, who is trusted with the service of writs and certain police duties, but he is still of higher rank than the mere Corchete or arresting officer. The title has also been given to inspectors of weights and measures in marketplaces, and similar officials.
In modern Spanish usage it can also mean Sheriff Law enforcement officer, especially in United States. Also colloquially called Jerife, Cherif, and Sherif.
There were two types of Aguacils: The Aguaciles Mayores (Chief Justice) and Aguaciles Menores (Justice).
The Aguacils of higher importance were the Aguaciles Mayores. These positions were held by the most prominent families, so they approximated the office of Regidores. (At first they were also in charge of the local prison (jail), but this function was passed very soon to the responsibility of the Alcaide or warden.) Their function was to arrest people provided by the Inquisidor or investigators and the seizure of their property. To do this one had to be accompanied by the recipient, their family members and the Secretary (minister) of Arrests (sheriff). He could seek the support of civil authorities. It also ensured the safety of the detainees (defendants), because they had no communications with others except, of course, those authorized by the investigators. Among the junior officers, the Alguacil Mayor held the largest category with the Secret Notaries. The others functions of an Aguacil Mayor were:
A haunting feeling comes throughout a darkened room
The air turns thick at this ritual of doom
Candles start to flicker as the image now appears
Alla Xul's presence, the master of all fears
Enlightened by its sight, I now feel hypnotized
Within a realm of darkness, I see two glowing eyes
Bowing down before it to feel its might stare
Manifested power given by the necro-prayer
It speaks the ancient tongues
Embraced by power
Spawn of the abyss
Invoked this night
Sumerian evil god
