Activism consists of intentional efforts to promote, impede or direct social, political, economic, or environmental change. Activism can take a wide range of forms from writing letters to newspapers or politicians, political campaigning, economic activism such as boycotts or preferentially patronizing businesses, rallies, street marches, strikes, sit-ins, and hunger strikes.

Activists can function in roles as public officials, as in judicial activism. Arthur Schlesinger Jr. introduced the term "judicial activism" in a January 1947 Fortune magazine article titled "The Supreme Court: 1947."

Some activists try to persuade people to change their behavior directly, rather than to persuade governments to change or not to change laws. The cooperative movement seeks to build new institutions which conform to cooperative principles, and generally does not lobby or protest politically, and clergymen often exhort their parishioners to follow a particular moral code or system.

As with those who engage other activities such as singing or running, the term may apply broadly to anyone who engages in it even briefly, or be more narrowly limited to those for whom it is a vocation, habit or characteristic practice. In the narrower sense environmental activists that align themselves with Earth First or Road Protestors would commonly be labelled activists, whilst a local community fighting to stop their park or green being sold off or built on would fit the broader application, due to their using similar means to similarly conservative ends. In short activism is not always an action by Activists.

Michelle LaVaughn Robinson Obama (born January 17, 1964) is the wife of the 44th and incumbent President of the United States, Barack Obama, and is the first African-American First Lady of the United States. Raised on the South Side of Chicago, Obama attended Princeton University and Harvard Law School before returning to Chicago and to work at the law firm Sidley Austin, where she met her future husband. Subsequently, she worked as part of the staff of Chicago mayor Richard M. Daley, and for the University of Chicago Medical Center.

Throughout 2007 and 2008, she helped campaign for her husband's presidential bid and delivered a keynote address at the 2008 Democratic National Convention. She is the mother of two daughters, Malia and Sasha, and is the sister of Craig Robinson, men's basketball coach at Oregon State University. As the wife of a Senator, and later the First Lady, she has become a fashion icon and role model for women, and an advocate for poverty awareness, nutrition and healthy eating.

Jody Williams (born 1950) is an American political activist known around the world for her work in banning antipersonnel landmines, her defense of human rights – and especially those of women, and her efforts to promote new understandings of security in today’s world.

She served as the founding coordinator of the International Campaign to Ban Landmines (ICBL) from early 1992 until February 1998. Prior to that work, she spent eleven years on various projects related to the wars in Nicaragua and El Salvador.

In an unprecedented cooperative effort with governments, UN bodies and the International Committee of the Red Cross, she served as a chief strategist and spokesperson for the ICBL, which she developed from two non-governmental organizations (NGOs) with a staff of one – herself – to an international powerhouse of 1,300 NGOs in ninety countries.

From its small beginning and official launch in 1992, Williams and the ICBL dramatically achieved the campaign’s goal of an international treaty banning antipersonnel landmines during a diplomatic conference held in Oslo in September 1997. Three weeks later, she and the ICBL were awarded the Nobel Peace Prize. At that time, she became the tenth woman – and third American woman – in its almost hundred-year history to receive the Prize.

Avram Noam Chomsky (/ˈnoʊm ˈtʃɒmski/; born December 7, 1928) is an American linguist, philosopher,cognitive scientist, historian, and activist. He is an Institute Professor and Professor (Emeritus) in the Department of Linguistics & Philosophy at MIT, where he has worked for over 50 years.

Ideologically identifying with anarcho-syndicalism and libertarian socialism, Chomsky is known for his critiques of U.S. foreign policy and contemporary capitalism, and he has been described as a prominent cultural figure. His media criticism has included Manufacturing Consent: The Political Economy of the Mass Media (1988), co-written with Edward S. Herman, an analysis articulating the propaganda model theory for examining the media.

According to the Arts and Humanities Citation Index in 1992, Chomsky was cited as a source more often than any other living scholar from 1980 to 1992, and was the eighth most cited source overall. Chomsky is the author of over 100 books. He is credited as the creator or co-creator of the Chomsky hierarchy, the universal grammar theory, and the Chomsky–Schützenberger theorem.

Miles was a captain in the King's New Brunswick Regiment from 1793 to 1802. He married Elizabeth Harding in 1800 after the death of his first wife. He was elected to the provincial assembly in 1802 after a number of voters who had voted for Samuel Denny Street were found to be ineligible by the sheriff. Miles was an unsuccessful candidate in 1809 but was elected in the three elections that followed. During his time in the assembly, Miles never opposed measures introduced by the government. He was a magistrate for Sunbury County and served as a justice for the Inferior Court of Common Pleas. Miles died in Maugerville at the age of 78.
