"Our lives begin to end the day we become silent about things that matter." These famous words have once again echoed loudly as the world marked Martin Luther King Jr. Day.
The commemoration comes at a critical moment when the world is grappling with geopolitical instability, rising authoritarianism, breaches of the United Nations Charter, and widespread civil unrest, from Venezuela, Greenland, the Democratic Republic of Congo, Ukraine, Gaza, Sudan and Iran to Uganda, all of which threaten global peace.
Just days before launching the so-called Board of Peace during the World Economic Forum, former United States president Donald Trump issued a proclamation on January 19, attributing the initiative to the legacy of the 1964 Nobel Peace Prize laureate, Martin Luther King Jr, an enduring icon of civil rights, peace and inclusivity.
The proclamation followed a long-standing tradition dating back to President Ronald Reagan, who designated every third Monday of January as Martin Luther King Jr. Day to honour a man who never bowed to racial injustice, systemic exclusion and inequality.

Trump's proclamation came amid a powerful tribute from former president Barack Obama, whose message resonated deeply with millions who continue to cherish King's legacy.
"Dr Martin Luther King Jr dedicated his life fighting for equity and justice. He taught us that even in the face of intimidation and discrimination, we must never stop working towards a better future, a lesson that feels especially relevant today," Obama wrote.
He added, "Change has never been easy. It takes persistence and determination and requires all of us to speak out and stand up for what we believe in. As we honour Dr King today, let's draw strength from his example and do our part to build on his legacy."
Obama's words serve as a timely reminder to this generation to reflect deeply on Martin Luther King Jr's legacy, particularly in moments of uncertainty and crisis.
King will forever be remembered for his leadership in the Southern Christian Leadership Conference, his organisation of mass civil rights movements, his unwavering voice for the voiceless, and his steadfast commitment to nonviolent activism in the pursuit of equality, justice and human dignity.
His advocacy culminated in transformative milestones, including the Civil Rights Act of 1964, the Voting Rights Act of 1965, the awarding of the Nobel Peace Prize in 1964, and significant pressure that contributed to the eventual end of the Vietnam War. These achievements reshaped the social, political and economic fabric of the United States.
One of the most enduring lessons from King's work was his insistence on nonviolence as a tool for change. Through peaceful means, he advanced the right to vote, fair trials, access to public education, government services and shared public spaces for all Americans.
That philosophy transcended borders. King's nonviolent strategies inspired liberation and reform movements across the world, from the anti-apartheid struggle in South Africa to the 1986 People Power Revolution in the Philippines, the Baltic independence movements in Latvia, Estonia and Lithuania, and, more recently, global climate justice campaigns.
In contrast, some freedom struggles elsewhere have turned to armed rebellion, violent protests and chaos. Yet King's legacy reminds us that sustainable change is more often achieved through moral authority than brute force.
Even the growing cancer of authoritarianism, kleptocracy and totalitarianism that continues to erode democratic spaces worldwide can be confronted through nonviolent resistance.
Emulating King's legacy is not an abstract ideal. It involves peaceful demonstrations, civil disobedience, protest art and music, economic boycotts, consciousness-raising and information activism, all of which remain powerful tools in the fight for justice and democracy.
King delivered more than 2,500 speeches during his lifetime. Many of his words remain sources of hope, courage, perseverance and resilience for activists, scholars, journalists and civil society actors across generations.

One of his most quoted reflections remains deeply relevant: "The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy." Silence in the face of injustice, King warned, is complicity.
That message must resonate with millennials, Generation Z and future generations: speaking truth to power, even amid intimidation and repression, is not optional, it is a moral duty.
Regardless of race, gender, faith, social status or ideology, we are all called to uphold King's legacy by shaping human rights-based policies that protect human dignity for all.
In a world increasingly defined by injustice, extremism, inequality, geopolitical tension and civil unrest, Martin Luther King Jr's legacy is no longer just history. It is now our shared responsibility.
