Some of the most famous activists including Martin Luther King Jr., Rosa Parks, Nelson Mandela, Malala Yousafzai, and Greta Thunberg have worked to make people’s lives better throughout the world while celebrity advocates such as Angelina Jolie and Bono have used public platforms to support causes important to them. And while their contributions have all had a positive effect, they create positive impact in different ways including organizing to build collective movements,  using advocacy to represent affected communities and raises awareness and using philanthropy to provide financial resources to further their causes.

In this article we’ll dive into how each role works, show their real world organizations and their effects and look at the practical lessons anyone in the nonprofit sector can use to push their own mission forward.

1. Famous Activists and Advocates at a Glance 

Here’s a quick list of the activists and advocates we’ll be looking into today.

What is the Difference Between an Activist, Advocate and Philanthropist? 

Although all three of these roles are important when it comes to public movements, they are different in the ways they use to push forward positive change. 

• Activism involves organized effort primarily through community organizing and grassroots mobilization designed to challenge systemic barriers and achieve policy or structural change in a concrete way.
• Advocacy focuses on supporting a specific cause, policy or affected community by raising awareness, educating the public of the problems or speaking before decision making bodies that have the power to change policies and laws to benefit those negatively effected.
• Philanthropy provides the financial capital such as grants or direct resources to sustain charitable programs and public benefit organizations while they work to bring change.

So while it may seem that philanthropy is an important aspect of any cause, and it definitely has its place, accepting donations for a cause is not ‘activism’ in this context, it is simply funding the activists ability to effect change or greater awareness.

The 16 individuals featured in this guide below were selected based on public recognition and documented contributions across varied causes, methods, and eras in order to highlight how organizing, public representation and financial support operate in practice across historical and contemporary contexts so today’s nonprofits and NGOs can see the ways true activism can be used in their own mission or cause. 

2. Celebrity Activists and Famous Advocates 

1. Angelina Jolie — Refugee Advocacy

Angelina Jolie is an American actress and has been using her celebrity status in order to help displaced populations and highlight humanitarian crises since 2001 when she became a UNHCR Goodwill Ambassador. And continuing in that role until 2012 before being appointed Special Envoy, a role she held until concluding her formal tenure in December 2022. She conducted over 60 field missions to advocate for displaced populations and highlight humanitarian crises across the two decades of working with the UN. And even now Jolie continues to push for advocacy focused on international refugee rights, humanitarian aid and global conflict responses independently. See UNHCR’s account of Jolie’s service.

2. Bono — Global Health and Anti-Poverty Advocacy

As the frontman of U2, Bono has been showing how fame can be turned into real political leverage and has been doing so for over two decades all beginning when he co-founded a foundation DATA in 2002 that was later merged to form the ONE Campaign which is now seen as a global powerhouse fighting extreme poverty and preventable disease. Bono continued to push even harder when in 2006 he launched (RED) to rally giant corporate brands into funding global health crises and lobbying world leaders for structural debt relief and policy changes in order to bring about positive change. See ONE’s Bono profile.

3. Emma Watson — Gender-Equality Advocacy

Actress Emma Watson become a household name for her role in Harry Potter, and has since continued her career while also advocating for gender equality. In 2014 she was named a UN Women Goodwill Ambassador and has continued using her massive cultural reach to supercharge an existing UN effort ever since rather than going it alone. Her powerful UN speech launching the HeForShe campaign sparked worldwide conversation by inviting men and boys to actively stand up for gender equality as part of the intuitive and actively work together with women to push the movement along. See UN Women’s organizational history.

4. Leonardo DiCaprio — Environmental Advocacy and Philanthropy

Leonardo DiCaprio was putting his Hollywood star power behind the planet long before climate change dominated daily news, founding the Leonardo DiCaprio Foundation back in 1998 shortly after the movie Titanic came out. By 2014 he was appointed as a UN Messenger of Peace for Climate for his advocacy. Then in 2021 DiCaprio made the decision to merge his foundation and become a co-founder of Re:wild, a conservation group dedicated to protecting species and restoring wild ecosystems back to their original states. Today the actor is still hard at work and serves on Re:wild's founding board as he blends his own philanthropic funding with global storytelling to drive real dollars toward frontline conservationists. See Re:wild’s DiCaprio profile. 

5. Beyoncé — Philanthropy and Community Support

During her 2013 Mrs. Carter Show World Tour, Beyoncé launched BeyGOOD, a philanthropic platform built to bring direct relief to local communities through a host of initiatives created to specifically address social inequalities though educational scholarships, entrepreneurial grants and community response efforts. Since its inception the platform has grown to include global campaigns and has expended to proving job training grants, housing aid and emergency disaster relief throughout the world. It’s a textbook example of how an artist can channel their notoriety and touring momentum into long term community giving. See BeyGOOD’s history.

6. John Legend — Criminal Justice Advocacy

Grammy winning musician John Legend turned his attention to systemic reform in 2014 when he decided to take on America’s justice system and it’s increasing numbers of people incarcerated or being held in jail simply because they couldn’t afford bail. So in 2014 launched FREEAMERICA which states as its mission, ‘We are working to end mass incarceration by using the power of storytelling, education, and advocacy to uplift the voices of those impacted by the criminal justice system.’ He does this through using the voices of formerly incarcerated individuals, hosting panel discussions with policymakers and backing local grassroots organizers fighting for policy change. See FREEAMERICA’s official platform at FREEAMERICA.

7. Shakira — Children’s Education Advocacy

Shakira’s (Shakira Isabel Mebarak Ripoll) work to change the lives of children all throughout Columbia by physically building brick and mortar state of the art schools across the country started when she was just 18 years old! The global pop star founded Pies Descalzos Foundation in 1997 as a way to give the children of Columbia a step up through education and nutritional assistance. Her hands on work in South America led to her appointment as a UNICEF Goodwill Ambassador in 2003, where she continues to advocate worldwide for early childhood education through an approach that pairs long term brick-and-mortar school building with global diplomatic advocacy. See UNICEF’s Shakira profile.

8. Selena Gomez — Youth Mental Health Support

In 2020, multihyphenate star Selena Gomez launched the Rare Impact Fund with an ambitious goal, raise $100 million to expand mental health services specifically for young people. To initially fund operations she pledged that 1% of all sales from her beauty brand would go to the fund, making it a sustainable funding model that directly grants money to youth mental health organizations and educational resources.

The foundation focuses on youth mental wellness, funding community programs, conducting research on young people's well-being and providing mental health first aid training for those also trying to help. And rather than offering clinical treatment, the organization focuses on peer support, kindness and mental health resources to help those in need. See the Born This Way Foundation.

10. Millie Bobby Brown — Children’s Rights Advocacy

In November 2018, Stranger Things star Millie Bobby Brown made history when she was named UNICEF’s youngest ever Goodwill Ambassador at just 14 years old.

See UNICEF’s appointment announcement.

3. Historical and Contemporary Activists Known for Their Advocacy

11. Martin Luther King Jr. — Civil Rights Organizing

Dr. Martin Luther King Jr. was a master strategist whose leadership transformed the American Civil Rights Movement. As president of the Southern Christian Leadership Conference (SCLC), he helped organize landmark nonviolent protests, including the 1955–1956 Montgomery bus boycott which is still a major event taught in schools across America. Beyond dismantling legal segregation, King spent his final years uniting working class and poor people of all racial backgrounds, black, white and Indigenous alike through the Poor People’s Campaign to demand economic justice and fair wages. See the National Park Service on the Montgomery bus boycott.

12. Rosa Parks — Sustained Civil-Rights Activism

Long before her famous arrest on a Montgomery bus in December 1955, Rosa Parks was a dedicated activist working as secretary and youth leader for the local NAACP. And while many believe Rosa’s decision not to give her seat up that day was she was too tired to stand, the truth is it was a calculated, courageous act grounded in over a decade of civil rights organizing. And from that day forward until the day she dies, Parks spent her life advocating for racial justice and fair housing in her hometown of Detroit. See the National Park Service’s Rosa Parks biography.

13. Nelson Mandela — Anti-Apartheid Activism

Nelson Mandela dedicated his life to overthrowing South Africa’s brutal system of racial apartheid spending 27 years of his life in a political jail cell and calling for non-violent confrontations. It wasn’t until after he was released that he successfully led complex negotiations to end apartheid peacefully and was elected South Africa’s first Black president in 1994. Today, Mandella’s life is seen as an enduring symbol of resistance, reconciliation and democratic leadership. See the Nelson Mandela Foundation biography.

14. Malala Yousafzai — Girls’ Education Advocacy

After surviving an assassination attempt by the Taliban in 2012 for simply going to school in Pakistan, Malala Yousafzai refused to be silenced and in 2013 she co-founded the Malala Fund to fight for every girl's right to 12 years of free, safe, quality education. As the ultimate show of respect, she was awarded the Nobel Peace Prize at age 17 and became the youngest person ever to receive the prize. Today her organization still works to fund local education leaders around the world. See Malala Fund’s account of her work.

15. Greta Thunberg — Climate Activism

In August 2018, 15-year-old Greta Thunberg skipped school to sit alone outside the Swedish Parliament with a handmade sign that demanded lawmakers take action to save the climate. That quiet action sparked Fridays for Future, a youth movement that brought millions of students into the streets worldwide. Thunberg’s straightforward, science-backed speeches have called out world leaders and forced environmental policy to the top of the global agenda in cuntries around the world and shows that people of any age can have a major powerful impact. See Fridays for Future’s history.

16. Amal Clooney — Human Rights Advocacy

Amal Clooney is a world renowned international human rights barrister who represents political prisoners, persecuted journalists and victims of war crimes in international courts. In 2016, she and her husband co-founded the Clooney Foundation for Justice to hold human rights abusers accountable and provide free legal aid to vulnerable communities and persons being persecuted. Her work uses the power of international law to fight for justice on the ground and she is still fighting for human rights to this day. See the Clooney Foundation for Justice’s professional profile.

4. Young Celebrity Activists and Advocates Who Started Early

Age is never a barrier when it comes to making the world a better place. Just look at a few of the people below who started having a positive impact as young as 11 years old! 

Here are the two main ways young people step onto the world stage:

• Institutional Appointments: Actress Millie Bobby Brown made history in 2018 when she was named UNICEF’s youngest ever Goodwill Ambassador at just 14! She achieved this by leveraging her massive Hollywood fanbase to speak out on children’s rights and anti-bullying before these topics ever started to trend on social sites.
• Grassroots Movement Builders: Other youth leaders built their platforms from the ground up through pure persistence and believing what they had to say was worth saying. Malala Yousafzai was just 11 years old when she began blogging about girls' education under the Taliban’s rule in Pakistan, a truly dangerous thing to do at the time. Then there’s Greta Thunberg who started her solo school strike outside Swedish Parliament at age 15 which in turn sparked the worldwide Fridays for Future movement that is still making a positive impact to this day.

Whether stepping into an established ambassador role or standing on a sidewalk with a handmade sign, these young leaders prove that age is no barrier to driving real world change when you have something important to say.

5. Black Celebrity Activists and Advocates

There have been many powerful black voices across the world over the years, from civil rights to fighting powerful governments on racial injustice, their voices and paths of advocacy are just as varied as the causes they stood for as our list shows: 

• Movement Organizing & Structural Resistance: Historical titans like Dr. Martin Luther King Jr. and Rosa Parks worked to bring civil rights to all Americans while others like Nelson Mandela spent decades resisting South Africa's brutal apartheid system through non-violent means.
• Policy & Systemic Reform: Right now figures like musician John Legend are using their platforms to tackle systemic issues head-on while launching initiatives like FREEAMERICA to push for sweeping U.S. criminal justice reform.
• Direct Community Philanthropy: Cultural icons like Beyoncé focus heavily on direct mutual aid and financial support. Through BeyGOOD, she channels funding directly into disaster relief, small business grants and college scholarships in order to bring positive change to communities.

Organizing a political movement, lobbying for legal reform and funding community relief all have their place when it comes to creating real change. Knowing the difference can help you decide how you want to move forward, and what can be done when you are passionate about a cause.

6. What Celebrity Activism Can and Cannot Do

Teaming up with a prominent advocate can offer a ton of benefits for any charity. From boosting awareness, amplifying institutional campaign messaging, gaining media interest and opening doors to broader donor networks, these benefits aren’t always a guarantee that systemic change or guaranteed fundraising success will actually occur. This comes down to the fact that high profile endorsements cannot replace actual grassroots community leadership, hands on operational program execution or long term institutional funding.

So if you’re planning on seeking out these types of relationships, be sure that the spokesperson’s public record and values directly reflect your organization’s core mission and confirm the representative understands the specific issues facing your affected community rather than just offering generalized commentary. You should also make sure that the person’s celebrity doesn’t drown out your own messaging and define specific expectations, timelines and measurable outcomes for all the campaign activities they’ll be connected with.

7. Practical Lessons for Five Types of Nonprofits

Schools and PTOs — Combine Education with Student Voices

• Lesson: Ground every campaign in concrete educational needs while letting students speak for themselves.
• Event Application: Have students present the exact classroom project or equipment the event is funding when holding a fundraising event or gala.
• Key Metric: Track how many students actually participate and how well the funding was used for the need. Simply relying on ticket sales numbers is not enough.
• Accountability Rule: If using students as promotional props, get signed waivers from their parents to make sure there are no legal problems when it comes to sharing their stories or photos.

Faith Based Organizations — Organize Around Community Service

• Lesson: Build your campaigns around collaborative service that directly addresses your local community needs.
• Event Application: Host a community dinner where local partner charities present the specific programs your funds will support.
• Key Metric: Measure total service hours funded and track the final impact report delivered to donors.
• Accountability Rule: Keep all of your financial disbursements transparent and never claim a guest speaker endorses your specific religious doctrines.

Healthcare Foundations — Pair Awareness with Qualified Information

• Lesson: Pair real patient stories with verified medical expertise to ‘prove’ your message is both credible and your mission can create positive impact. 
• Event Application: Use real people such as a patient willing to share their story alongside a doctor explaining how the target program works.
• Key Metric: Track the exact percentage of raised funds delivered to stated patient programs.
• Accountability Rule: Protect patient privacy, avoid medical efficacy promises and never pressure individuals to share sensitive experiences if they’re not comfortable doing so.

Arts Organizations — Make Participation Part of the Appeal

• Lesson: Show your donors the real impact of the arts by using the art right at your event so they can see for themselves how your organization works. 
• Event Application: When you have an event try to have artists who have benefited from your work to share their stories on how they were able to create due to your charity’s generosity. 
• Key Metric: Use real metrics like funded student slots or program expansion rather than the audience’s applause.
• Accountability Rule: Secure proper permissions for all featured artwork and ensure participating artists receive fair, agreed upon compensation.

Community Nonprofits — Let Local Leaders Shape the Story

• Lesson: Let the people in your neighborhood speak out on the local priorities and speak about why your initiatives are so important.
• Event Application: Structure your annual gala around a panel of local residents that can articulate the project’s goals in a way that will resonate with the community. 
• Key Metric: Evaluate your success by measuring exactly what was accomplished against the goals set by the community.
• Accountability Rule: Always allow your local leaders to have decision making authority and allow them to receive credit for successes rather than an outside influencer.

What is the difference between activism and philanthropy?

Activism focuses on bringing awareness to a cause thorough grassroots organizing, campaign mobilization and movement building to change policies or systemic structures whereas philanthropy involves donating financial capital or resources to support charitable programs and nonprofit operations. While you can do both, giving a donation in itself is not activism. 

9. Wrapping up

Building momentum for a cause doesn’t require a celebrity endorsement to move the needle, plenty of nonprofits create momentum using clear messaging, authentic community leader’s voices, being transparent with their financials and showing their supporters the actual real world results of their generosity. The lesson here is to connect public awareness to clear fundraising goals as a way to keep your mission moving forward.
