Collective action in the context of "Activism"

Freedom of association encompasses both an individual's right to join or leave groups voluntarily, the right of the group to take collective action to pursue the interests of its members, and the right of an association to accept or decline membership based on certain criteria. It can be described as the right of a person coming together with other individuals to collectively express, promote, pursue and/or defend common interests.

Freedom of association is both an individual right and a collective right, guaranteed by all modern and democratic legal systems, including the United States Bill of Rights, article 11 of the European Convention on Human Rights, section 2 of the Canadian Charter of Rights and Freedoms, and international law, including articles 20 and 23 of the Universal Declaration of Human Rights and article 22 of International Covenant on Civil and Political Rights. The Declaration on Fundamental Principles and Rights at Work by the International Labour Organization also ensures these rights.

The use of force by states and inter-governmental organizations in international law is controlled by both customary international law and by treaty law. As a legal matter, the use of force may be justified only in self-defense or when authorized by the United Nations Security Council. The UN Charter reads in article 2(4):

This principle is now considered to be a part of customary international law, and has the effect of banning the use of armed force except for two situations authorized by the UN Charter. Firstly, the Security Council, under powers granted in articles 24 and 25, and Chapter VII of the Charter, may authorize collective action to maintain or enforce international peace and security. Secondly, Article 51 also states that: "Nothing in the present Charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a member of the United Nations." There are also more controversial claims by some states of a right of humanitarian intervention, reprisals and the protection of nationals abroad. Concomitant with Article 51’s right to self-defense it Article 2(4)’s prohibition against “the threat or use of force against the territorial integrity or political independence of any state."

Community-led total sanitation (CLTS) is a participatory approach used primarily in developing countries to improve sanitation and hygiene practices within communities. CLTS aims to achieve behavior change with a "trigger" that leads to spontaneous and long-term abandonment of open defecation practices, thereby improving community sanitation and overall health. The term "triggering" is central to the CLTS process. It refers to methods of igniting community interest in ending open defecation, usually by building simple toilets such as pit latrines. The effect of CLTS is two-fold: actions that increase self-respect and pride in one's community and actions that promote shame and disgust about one's open defecation behaviors. CLTS takes an approach to rural sanitation that works without hardware subsidies by facilitating communities to acknowledge the problem of open defecation, taking collective action to become "open defecation free," and improve sanitation.

The concept was developed around 2000 by Kamal Kar for rural areas in Bangladesh. CLTS became an established approach around 2011. Local governments may reward communities by certifying them with "open defecation free" (ODF) status. The original concept of CLTS purposefully did not include subsidies for toilet installations, as they might hinder the process.

Critical theory is a social, historical, and political school of thought and philosophical perspective which centers on analyzing and challenging systemic power relations in society, arguing that knowledge, truth, and social structures are fundamentally shaped by power dynamics between dominant and oppressed groups. Beyond just understanding and critiquing these dynamics, it explicitly aims to transform society through praxis and collective action with an explicit sociopolitical purpose.

Critical theory's main tenets center on analyzing systemic power relations in society, focusing on the dynamics between groups with different levels of social, economic, and institutional power. Unlike traditional social theories that aim primarily to describe and understand society, critical theory explicitly seeks to critique and transform it. Thus, it positions itself as both an analytical framework and a movement for social change. Critical theory examines how dominant groups and structures influence what society considers objective truth, challenging the very notion of pure objectivity and rationality by arguing that knowledge is shaped by power relations and social context. Key principles of critical theory include examining intersecting forms of oppression, emphasizing historical contexts in social analysis, and critiquing capitalist structures. The framework emphasizes praxis (combining theory with action) and highlights how lived experience, collective action, ideology, and educational systems play crucial roles in maintaining or challenging existing power structures.

Military sociology is a subfield within sociology. It corresponds closely to C. Wright Mills's summons to connect the individual world to broader social structures. Military sociology aims toward the systematic study of the military as a social group rather than as a military organization. This highly specialized sub-discipline examines issues related to service personnel as a distinct group with coerced collective action based on shared interests linked to survival in vocation and combat, with purposes and values that are more defined and narrow than within civil society. Military sociology also concerns civil-military relations and interactions between other groups or governmental agencies.

Self-categorization theory is a theory in social psychology that describes the circumstances under which a person will perceive collections of people (including themselves) as a group, as well as the consequences of perceiving people in group terms. Although the theory is often introduced as an explanation of psychological group formation (which was one of its early goals), it is more accurately thought of as general analysis of the functioning of categorization processes in social perception and interaction that speaks to issues of individual identity as much as group phenomena. It was developed by John Turner and colleagues, and along with social identity theory it is a constituent part of the social identity approach. It was in part developed to address questions that arose in response to social identity theory about the mechanistic underpinnings of social identification.

Self-categorization theory has been influential in the academic field of social psychology and beyond. It was first applied to the topics of social influence, group cohesion, group polarization, and collective action. In subsequent years the theory, often as part of the social identity approach, has been applied to further topics such as leadership, personality, outgroup homogeneity, and power. One tenet of the theory is that the self should not be considered as a foundational aspect of cognition, but rather the self should be seen as a product of the cognitive system at work.
