Intentional community in the context of "Kibbutz"

The Spanish Revolution was a social revolution that began at the outbreak of the Spanish Civil War in 1936, following the attempted coup to overthrow the Second Spanish Republic and arming of the worker movements and formation of militias to fight the Nationalists. It featured takeover of power at local levels by the Spanish workers' organizations and social movements, seizure and reorganization of economic facilities directed by trade union groups and local committees, and widespread implementation of socialist, more narrowly, libertarian socialist and anarchist organizational principles throughout various portions of the Republican zone, primarily Catalonia, Aragon, Andalusia, and parts of the Valencian Community.

Much of the economy of Spain was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%. Factories were run through worker committees, and agrarian areas became collectivized and run as libertarian socialist communes. Many small businesses, such as hotels, barber shops, and restaurants, were also collectivized and managed by their former employees. The revolutionary principles implemented with the revolution continued to evolve as much as the Republican zone existed, until the end of the civil war with the victory of the Nationalists.

Multifamily residential, also known as multidwelling unit (MDU), is a classification of housing where multiple separate housing units for residential inhabitants are contained within one building or several buildings within one complex. Units can be next to each other (side-by-side units), or stacked on top of each other (top and bottom units). Common forms include apartment building and condominium, where typically the units are owned individually rather than leased from a single building owner. Many intentional communities incorporate multifamily residences, such as in cohousing projects.

Housing units in multifamily housing have greater per capita value than single family homes. Multifamily housing has beneficial fiscal externalities, as their presence reduces property tax rates in the community. Contrary to some popular discourse, in particular from NIMBYs, multifamily housing are a lower fire hazard.

An ecovillage is a traditional or intentional community that aims to become more socially, culturally, economically and/or environmentally sustainable. An ecovillage strives to have the least possible negative impact on the natural environment through the intentional physical design and behavioural choices of its inhabitants. It is consciously designed through locally owned, participatory processes to regenerate and restore its social and natural environments. Most range from a population of 50 to 250 individuals, although some are smaller, and traditional ecovillages are often much larger. Larger ecovillages often exist as networks of smaller sub-communities. Some ecovillages have grown through like-minded individuals, families, or other small groups—who are not members, at least at the outset—settling on the ecovillage's periphery and participating de facto in the community. There are currently more than 10,000 ecovillages around the world.

Ecovillagers are united by shared ecological, social-economic and cultural-spiritual values. Concretely, ecovillagers seek alternatives to ecologically destructive electrical, water, transportation, and waste-treatment systems, as well as the larger social systems that mirror and support them. Many see the breakdown of traditional forms of community, wasteful consumerist lifestyles, the destruction of natural habitat, urban sprawl, factory farming, and over-reliance on fossil fuels as trends that must be changed to avert ecological disaster and create richer and more fulfilling ways of life.

The United Society of Believers in Christ's Second Appearing, more commonly known as the Shakers, are a millenarian restorationist Christian sect founded c. 1747 in England and then organized in the United States in the 1780s. They were initially known as "Shaking Quakers" because of their ecstatic behavior during worship services.

Espousing egalitarian ideals, the Shakers practice a celibate and communal utopian lifestyle, pacifism, uniform charismatic worship, and their model of equality of the sexes, which they institutionalized in their society in the 1780s. They are also known for their simple living, architecture, technological innovation, music, and furniture. Women took on spiritual leadership roles alongside men, including founding leaders such as Jane Wardley, Ann Lee, and Lucy Wright. The Shakers emigrated from England and settled in British North America, with an initial settlement at Watervliet, New York (present-day Colonie), in 1774.

A social experiment is a method of psychological or sociological research that observes people's reactions to certain situations or events. The experiment depends on a particular social approach where the main source of information is the participants' point of view and knowledge. To carry out a social experiment, specialists usually split participants into two groups — active participants (people who take action in particular events) and respondents (people who react to the action). Throughout the experiment, specialists monitor participants to identify the effects and differences resulting from the experiment. A conclusion is then created based on the results. Intentional communities are generally considered social experiments as each is a practical application of a theory.

Social psychology offers insight into how individuals act in groups and how behavior is affected by social burdens and pressures. In most social experiments, the subjects are unaware that they are partaking in an experiment as to prevent bias; however, this may bring ethical issues (see ethics section). Several "actors" or "plants" are used to study social behaviors. Companies have also used social experiments to collect consumer data and their opinions about a product or a particular topic.

The American Left refers to the groups or ideas on the left of the political spectrum in the United States. It is occasionally used as a shorthand for groups aligned with the Democratic Party. At other times, it refers to groups that have sought egalitarian changes in the economic, political, and cultural institutions of the United States. Various subgroups with a national scope are active. Liberals and progressives believe that equality can be accommodated into existing capitalist structures, but they differ in their criticism of capitalism and on the extent of reform and the welfare state. Anarchists, communists, and socialists with international imperatives are also present within this macro-movement. Many communes and egalitarian communities have existed in the United States as a sub-category of the broader intentional community movement, some of which were based on utopian socialist ideals. The left has been involved in both the Democratic and Republican parties at different times, having originated in the Democratic-Republican Party as opposed to the Federalist Party.

Although left-wing politics came to the United States in the 19th century, there are currently no major left-wing political parties in the country. Despite existing left-wing factions within the Democratic Party, as well as minor third parties such as the Green Party, Communist Party USA, Party for Socialism and Liberation, American Communist Party, Workers World Party, Socialist Party, and American Solidarity Party (a Christian democratic party leaning left on economics), there have been few representatives of left-leaning third parties in Congress. Academic scholars have long studied the reasons why no viable socialist parties have emerged in the United States. Some writers ascribe this to the failures of socialist organization and leadership, some to the incompatibility of socialism with American values, and others to the limitations imposed by the United States Constitution. Vladimir Lenin and Leon Trotsky were particularly concerned because it challenged orthodox Marxist beliefs that the most advanced industrial country would provide a model for the future of less developed nations. If socialism represented the future, then it should be strongest in the United States. While branches of the Working Men's Party were founded in the 1820s and 1830s in the United States, they advocated land reform, universal education and improved working conditions in the form of labor rights, not collective ownership, disappearing after their goals were taken up by Jacksonian democracy. Samuel Gompers, the leader of the American Federation of Labor, thought that workers must rely on themselves because any rights provided by government could be revoked.

A gated community (or walled community) is a form of residential community or housing estate containing strictly controlled entrances for pedestrians, bicycles, and automobiles, and often characterized by a closed perimeter of walls and fences. Gated communities usually consist of small residential streets and include various shared amenities. For smaller communities, these amenities may include only a park or other common area. For larger communities, it may be possible for residents to stay within the community for most daily activities. Gated communities are a type of common interest development, but are distinct from intentional communities.

For socio-historical reasons, in the developed world they exist primarily in the United States.

Cohousing is an intentional, self-governing, cooperative community where residents live in private homes often clustered around shared space. The term originated in Denmark in the late 1960s. Families live in attached or single-family homes with traditional amenities, usually including a private kitchenette. As part of the communal orientation, shared spaces typically feature a common house, which may include a large kitchen and dining area, laundry, and recreational spaces. Walkways, open space, parking, playgrounds and gardens are common examples of shared outdoor spaces designed to promote social interactions. Neighbors also often share resources like tools, babysitting and creative skills.

Neighbors collaboratively plan and manage community activities and shared spaces while maintaining their own income and private lives. The legal structure is typically a homeowner association or housing cooperative, and some use community land trusts. To promote the common good, cohousing members regularly share meals, attend meetings, and participate in community work days. As part of cohousing's social nature, neighbors gather for parties, games, gardening, musical performances, movies, sports, and celebrations. Living in cohousing makes it easy for residents to form clubs, organize child and elder care, share information, free cycle and carpool.

Permaculture is an approach to land management and settlement design that adopts arrangements observed in flourishing natural ecosystems. It includes a set of design principles derived using whole-systems thinking. It applies these principles in fields such as regenerative agriculture, town planning, rewilding, and community resilience. The term was coined in 1978 by Bill Mollison and David Holmgren, who formulated the concept in opposition to modern industrialized methods, instead adopting a more traditional or "natural" approach to agriculture.

Multiple thinkers in the early and mid-20th century explored no-dig gardening, no-till farming, and the concept of "permanent agriculture", which were early inspirations for the field of permaculture. Mollison and Holmgren's work from the 1970s and 1980s led to several books, starting with Permaculture One in 1978, and to the development of the "Permaculture Design Course" which has been one of the main methods of diffusion of permacultural ideas. Starting from a focus on land usage in Southern Australia, permaculture has since spread in scope to include other regions and other topics, such as appropriate technology and intentional community design.
