The íciadeSegurançaPúPolícia de Segurança Pública MHTE (PSP; Public Security Police) is the national civil police force of Portugal. Part of the Portuguese security forces, the mission of the PSP is to defend Republican democracy, safeguarding internal security and the rights of its citizens. Despite many other functions, the force is generally known for policing urban areas with uniformed police officers, while rural areas are normally policed by National Republican Guard (GNR), the country's national gendarmerie force. PSP is focused in preventive policing, only investigating minor crimes. Investigation of serious crimes falls under the Judicial Police responsibility, which is a separate agency.
Since October 2023, the PSP is now in charge of controlling the Portuguese borders (alongside the GNR), with the dissolution of the SEF force.
History
Like most of Europe, until the Middle Ages the defence of public order was the responsibility of local communities, under the authority of feudal lords and courts.
In Portugal, there are few references to the administration of justice until the second half of the 15th century. With the reign of King Afonso V (under the regency of Infante Pedro) came the first ordinances and penal codes, known as the Ordenações Afonsinas. These ordinances were reissued during the reign of King John I in 1514, after various changes under Manuel I. Some of the early judicial measures came from the early nobles. Afonso Henriques ordered the incarceration of women who lived with elements of the clergy, while in the era of Afonso II, under the influence of Visigothic codes and Roman law resulted in the appearance of the first general laws. Similarly, Afonso III punished anyone who assaulted and robbed the home of another. King Pedro I, the Just, decreed that anyone who falsified coins, gold or silver objects would have their hands and feet amputated.
However, criminals were provided shelters by which to flee justice: the churches, monasteries and "privileged" lands. These privileged lands became areas of thieves and criminals, which resulted in King John extinguishing these areas. This was also something that King Fernando did with bairros, and only churches and convents became sanctuaries.
The first corps of police agents, the Quadrilheiros, was created by Fernando I, on 12 September 1383, consisting of 20 members, who were recruited by force from the strongest physical men, to serve Lisbon. These men were subject to the town council for three years, and required to swear fealty and carry a weapon (a staff), which they would display at their homes, representing a symbol of their authority to arrest and direct criminals to the Corregedores (magistrates). Since these men never received payment for their services, and since these activities were dangerous, most chose to escape the responsibility. For most, these services were intolerable, with little prestige, at various times resulting in bruises and wounds in the execution of their tasks. Owing to this, by 1418, these constables were not required to circle the town. Later, Afonso V provided the Quadrilheiros, on 10 June 1460, with several social and economic privileges. However, these would disappear over time.
Even as Afonso V put into action other laws, regulations, advisories and ordinances, many were ineffective. King Sebastian promulgated laws on 31 January 1559, 17 January 1570, 12 July and 13 August 1571, to reinforce the laws of Fernando I, Edward and Afonso V. To compensate the diminishing benefits of their service, the Quadrilheiros were exempt from paying taxes or military service. Sebastian also ordered that Lisbon be divided into barrios, and that each should be administered by an official of justice, with discretionary powers. On 12 March 1603, King Philip II ordered new regulations for the Quadrilheiros to reinforce their authority. The Lisbon Council, on 30 January 1617, determined that Quadrilheiros should have a label over their doors to identify them, and that the King should confer on them special privileges, such as sitting at the council table. King John IV of Portugal provided a new charter, and a decree on 29 November 1644, forced them (under terrible sanctions) to serve the public, working in the day and evenings. By the first half of the 18th century, little had improved. There continued to be a lack of policing, resulting in leis in 1701, 1702 and 1714. As new circuits were created to blanket the city, many of the criminals were aware that the laws transformed the situation into forgettable enclaves. The Quadrilheiros continued to be a poor class, due to their limitations, resulting in poor public order.
