Rajavi has stated that her political activism started when she was twenty-two after her sister Narges was killed by SAVAK.
Then she became a member of the People's Mojahedin of Iran (PMOI/MEK), and began her political career.
Maryam Rajavi served as deputy commander and MEK Secretary General until 1993.
On 22 October 1993, the NCRI elected Maryam to be "Iran’s interim President" if the NCRI were to assume power in Iran.

Rajavi served as an organizer of the anti-Shah student movement in the 1970s.
In 1979, she became an official of the social section of the PMOI/MEK, where she served until 1981.
Rajavi was a parliamentary candidate in 1980.

In 1982, Rajavi was transferred to Auvers-sur-Oise, Île-de-France where the political headquarters of the Mojahedin was located.

In 1985, she became Joint-Leader of the PMOI and served as the Secretary General between 1989 and 1993.

In a statement that condemned the ISIS attacks against Iran's parliament and the tomb of the Islamic Republic's founder, Rajavi stated: "ISIS's conduct clearly benefits the Iranian regime's Supreme Leader Khamenei, who wholeheartedly welcomes it as an opportunity to overcome his regime's regional and international impasse and isolation.
The founder and the number one state sponsor of terror is thus trying to switch the place of murderer and the victim and portray the central banker of terrorism as a victim."

A 10-point manifesto published by Maryam Rajavi sets out a programme to transform Iran.
She states her commitment to the Universal Declaration of Human Rights and to other international instruments.
She calls for the abolition of the death penalty, the creation of a modern legal system and the independence of judges.
Rajavi would end Tehran’s funding of Hamas, Hezbollah and other militant groups and is committed to peaceful coexistence, relations with all countries and respect for the United Nations charter.
 The manifesto also contains the statement that 'We recognize private property, private investment and the market economy.'.
In June 2020, a majority of members of the House of Representatives backed a “bipartisan resolution” supporting Maryam Rajavi and the NCRI’s “call for a secular, democratic Iran” while “condemning Iranian state-sponsored terrorism”.
The resolution, backed by 221 lawmakers (including Louie Gohmert and Sheila Jackson Lee), gave support to the Rajavi’s 10-point plan for Iran’s future (which include “a universal right to vote, market economy, and a non-nuclear Iran”) while calling on the prevention of “malign activities of the Iranian regime’s diplomatic missions.”

Rajavi presented her plan at the Council of Europe in 2006, which supports complete gender equality in political and social rights and, specifically, a commitment to equal participation of women in political leadership.
Her 10-point plan for the future of Iran stipulates that any form of discrimination against women would be abolished and that women would enjoy the right to choose their clothing freely.
It also includes the ending of cruel and degrading punishments.

In October 2011, Theresa May banned Maryam Rajavi from coming to Britain in a trip where she was to "explain how women are mistreated in Iran".
The high court then sued Theresa May, with Lord Carlile of Berriew (the Government's former independent reviewer of counter-terrorism laws) saying that May's decision "could be viewed as appeasing the Mullahs".
In 2014, the Supreme Court of the United Kingdom dismissed an appeal from Lord Carlile of Berriew QC and others and upheld it to maintain the ban, which had originally being implemented in 1997.
Members of the UK House of Lords argued that the Home Secretary was "violating Article 10 (freedom of expression) of the European Convention of Human Rights (the Convention)", saying that "Home Secretary’s reasons were legally irrelevant, because they depended on the potential reaction of a foreign state which did not share the values embodied in the Convention."
