Laws of the Indies
The Laws of the Indies (Spanish: Leyes de Indias) are the entire body of laws issued by the Spanish Crown for its American and Philippine possessions of its empire. They regulated social, political and economic life in these areas. The laws are composed of myriad decrees issued over the centuries and the important laws of the 16th century, which attempted to regulate the interactions between the settlers and natives, such as the Laws of Burgos (1512) and the New Laws (1542). Throughout the 500 years of Spanish presence in these parts of the world, the laws were compiled several times, most notably in 1680 under Charles II in the Recopilación de las Leyes de los Reynos de Indias (Compilation of the Laws of the Kingdoms of the Indies), which became the classic collection of the laws, despite the fact that later laws superseded parts of it and other compilations were issued. The 1680 compilation set the template by which the laws were organized.
The Spanish colonies in the Americas sometimes generated conflicts between indigenous peoples ('Natives' or 'Indians') and the Spanish colonists, due to the Indian Reductions and other policies. At the same time conflicts on policy and implementation occurred between the colonists and the Crown.
Two of the main sets of laws issued in the 16th century regulated Spanish contact with the indigenous people, an issue about which the crown quickly became concerned soon after the voyages of Christopher Columbus and his governorship. The Laws of Burgos (1512), signed by King Ferdinand II of Aragon, focused upon the welfare of the conquered native Americans. The issue was revisited after Bartolomé de las Casas brought attention to abuses being carried out by encomenderos. The Laws of Burgos were revised by the New Laws of 1542 issued by Charles I and quickly revised again in 1552, after the laws met resistance from colonists. These were then followed by the Ordinances Concerning Discoveries in 1573, which forbade any unauthorized operations against independent native Americans.
To guide and regularize the establishment of presidios (military towns), missions, and pueblos (civilian towns), King Phillip II developed the first version of the Laws of the Indies, a comprehensive guide composed of 148 ordinances to aid colonists in locating, building, and populating settlements. They codified the city planning process and represented some of the first attempts at a general plan. Signed in 1573, the Laws of the Indies are seen as the first wide-ranging guidelines towards design and development of communities. These laws were heavily influenced by Vitruvius' Ten Books of Architecture and Alberti's treatises on the subject.
After some of the northern Spanish colonies became a part of the United States, the Laws of the Indies were influential in the creation of regulations that guided the development in the United States, particularly the Land Ordinance of 1785, which introduced townships and sections as organizing devices.
Examples: town planning 
In Book IV of the 1680 compilation of The Laws of the Indies, plans were set forth for settlers in high detail on every facet of creating a community, including town planning. Examples of the diverse range of rules include:
- Those [Colonists] who should want to make a commitment to building a new settlement in the form and manner already prescribed, be it of more or less than 30 vecinos (freemen), (know that) it should be of no less than twelve persons and be awarded the authorization and territory in accordance with the prescribed conditions.
- Having made the selection of the site where the town is to be built, it must, as already stated, be in an elevated and healthy location; [be] with means of fortification; [have] fertile soil and with plenty of land for farming and pasturage; have fuel, timber, and resources; [have] fresh water, a native population, ease of transport, access and exit; [and be] open to the north wind; and, if on the coast, due consideration should be paid to the quality of the harbor and that the sea does not lie to the south or west; and if possible not near lagoons or marshes in which poisonous animals and polluted air and water breed.
- They [Colonists] shall try as far as possible to have the buildings all of one type for the sake of the beauty of the town.
- Within the town, a commons shall be delimited, large enough that although the population may experience a rapid expansion, there will always be sufficient space where the people may go to for recreation and take their cattle to pasture without them making any damage.
- The site and building lots for slaughter houses, fisheries, tanneries, and other business which produce filth shall be so placed that the filth can easily be disposed of.
These rules are part of a body of 148 regulations configuring any settlement according to the rule of Spain and its colonies. This continued as a precedent in all towns under Spanish control until the relinquishing of the land to others, as in the case of the American colonies and their growth; however, the Laws of the Indies still serve as an example to design guidelines for communities today.
The Laws specify many details of towns. A plan is made centered on a Plaza Mayor (main square) of size within specified limits, from which twelve straight streets are built in a rectilinear grid. The directions of the streets are chosen according to the prevailing winds, to protect the Plaza Mayor. There is great detail, down to a hospital for non-contagious cases near the church, and one for contagious diseases further away.
Most townships founded in any part of the Spanish Empire in America before the various parts became independent countries would have been planned according to the Laws, including many townships with Spanish names in what is now the United States. The rectilinear grid of streets is very different from the haphazard layout of the many old townships in Europe which just grew.
