Black History Matters: Reclaiming Our Legacy From Alkebulan to Black Excellence

My people. My brothers and sisters. Descendants of the transatlantic slave trade. This message is for you.

We are a people severed from our roots. A people whose ancestral knowledge was deliberately stolen, whose heritage was violently erased, whose history was rewritten by those who enslaved us. But we are still here. And it’s time we remember who we are.

We Come From Greatness

Before we were brought to these shores in chains, we came from Alkebulan—the ancient name for the African continent, meaning “mother of mankind” or “garden of Eden.” This was the land where civilization itself was born. Where humanity took its first breath.

Alkebulan: The Mother of Mankind

Our African heritage traces back to the cradle of civilization. Alkebulan was home to advanced societies long before European colonization renamed it “Africa.” This was the birthplace of humanity, science, mathematics, and spiritual wisdom.

Ancient African Civilizations and Advanced Knowledge

Our ancestors built the pyramids of Egypt—architectural marvels that modern engineers still struggle to replicate. They designed intricate water canal systems that irrigated vast empires. They studied the stars and followed the heavens, using astrology and astronomy to navigate, plant crops, and understand the universe. The Bible itself speaks of their wisdom, their knowledge, their connection to the divine order of creation.

We descended from advanced civilizations. From kings and queens. From scholars and builders. From astronomers and mathematicians. From healers and inventors.

This is our heritage. This is our bloodline.

What Was Stolen From Us

Then came the transatlantic slave trade—one of history’s greatest atrocities. Our people were ripped from their tribes, their families, their land. Indigenous Africans were captured, chained, and shipped across an ocean to a foreign land where everything they knew was stripped away.

Their names. Their languages. Their religions. Their customs. Their histories.

And most devastatingly—their ancestral knowledge.

The Breaking of the Ancestral Chain

In African culture, heritage is passed down orally from generation to generation. Elders teach the young about their lineage, their tribe’s history, their ancestors’ accomplishments. But when our people were enslaved, that chain was broken. Families were separated. Elders were silenced. Languages were forbidden. Cultural practices were beaten out of us.

How Oral Heritage Was Erased

The transatlantic slave trade didn’t just steal bodies—it stole stories, traditions, languages, and the sacred knowledge passed from elder to child. This deliberate erasure was designed to break our spirit and disconnect us from our power.

The knowledge stopped flowing.

We Are a People Without a Written Past

Today, many of us who are descendants of enslaved Africans cannot trace our family trees beyond a few generations. We hit a wall—a painful, empty space where our history should be.

Slave Records: Numbers Instead of Names

When we search for our roots, we find slave record books. Documents where our ancestors were listed as property. Counted as livestock. Owned by European slave holders who recorded them like cattle—by age, by physical condition, by monetary value.

That’s what they left us. Numbers on a page. Not names. Not stories. Not heritage.

The Gap in Our Family Trees

We are a people without a documented lineage. We don’t know which tribe we came from. We don’t know our ancestral homeland. We don’t know the names of our great-great-great-grandparents who survived the Middle Passage. We don’t know what languages they spoke, what songs they sang, or how they specifically worshipped.

We were robbed of our identity.

But We Are Still Here

Here’s what they didn’t count on: You cannot kill a people’s spirit.

Despite everything—despite slavery, despite Jim Crow, despite segregation, despite systemic racism, despite being told we were inferior, despite being denied education, despite being shut out of opportunities—we built anyway.

We created anyway. We invented anyway. We excelled anyway.

Because greatness is in our DNA.

Our Accomplishments Speak for Themselves

We may not have records of our African ancestors’ names, but we have something else: proof of our brilliance through our accomplishments.

From the moment we gained even the smallest measure of freedom, we began to create, innovate, and contribute to this nation and this world in extraordinary ways.

From Slavery to Innovation

Even during slavery, we invented. Benjamin Banneker built a wooden clock so precise it kept time for over 40 years. He helped design Washington, D.C. He published almanacs that rivaled Benjamin Franklin’s.

After emancipation, we continued. Garrett Morgan invented the traffic light and the gas mask. Madam C.J. Walker became America’s first female self-made millionaire. George Washington Carver revolutionized agriculture with over 300 uses for the peanut.

Black Inventors Who Changed the World

In the 20th century, we built the foundation of modern technology: - Mark Dean created the personal computer (holds 3 of IBM’s original 9 PC patents) - Dr. Shirley Ann Jackson’s research gave us fiber optic cables, caller ID, and call waiting - Katherine Johnson’s calculations put men on the moon - Lewis Latimermade the light bulb practical and affordable - Philip Emeagwali pioneered internet infrastructure through parallel computing

Today, we’re leading in artificial intelligence, biotechnology, space exploration, and every field imaginable.

This Is How We Reclaim Our Heritage

Since we cannot trace our lineage through genealogy records, we build our heritage through knowledge and accomplishment.

We teach our children about George Washington Carver and his 300 uses for the peanut.

We tell them about Lewis Latimer, who made the light bulb practical and affordable.

We show them Katherine Johnson, whose mathematical genius was essential to NASA’s success.

We celebrate Mark Dean, who holds three of IBM’s original nine PC patents.

We honor Dr. Patricia Bath, who invented laser cataract surgery and restored sight to millions.

We build our ancestral pride not through bloodline records, but through the undeniable proof of Black excellence across generations.

When our children see what we’ve accomplished—despite every obstacle, despite every barrier, despite being denied education and resources—they understand something profound:

Greatness runs through their veins.

Education Is Our Inheritance

This is why knowing Black history isn’t optional. It’s survival.

When you don’t know where you came from, you don’t know where you’re going. When you don’t see yourself reflected in history, you don’t believe you can make history.

But when you learn that every technology you use daily was touched by Black hands—the computer, the internet, the cell phone, the traffic light, the refrigerator, the light bulb—you realize something powerful:

We are not just survivors. We are builders. We are creators. We are innovators.

This knowledge becomes our inheritance. It replaces the genealogy records we don’t have. It fills the void left by the stolen ancestral knowledge.

We may not know our great-great-grandfather’s name, but we know what our people have accomplished. And that knowledge is power.

When You See Where You Came From, You Become Inspired to Do Greatness

There’s a reason they tried to hide our history. There’s a reason they didn’t teach us about Black inventors in school. There’s a reason our contributions were erased from textbooks.

Because they knew: if we understood our power, we would be unstoppable.

When a young Black child learns that their ancestors built pyramids, they stand taller.

When they learn that enslaved Africans were master craftsmen, engineers, and healers, they see themselves differently.

When they learn that Black inventors created the technology that runs the modern world, they believe they can do anything.

This is why we must teach our history. This is why we must celebrate our accomplishments. This is why we must never stop learning and sharing our stories.

Great Minds and Spirits Think Alike

Now, I want you to see something powerful. I want you to understand the magnitude of what we’ve accomplished right here in America—a land where we were brought as slaves, where we were told we were inferior, where we were denied basic human rights.

Despite all of that, look at what we built. Look at what we created. Look at what we contributed.

The comprehensive list that follows isn’t just a list of inventors. It’s proof of our genius. It’s evidence of our resilience. It’s a testament to the fact that you cannot suppress greatness.

As you read through the names and inventions of Black people in computing, software, cell phones, internet, and algorithms, remember this:

These are your people. This is your legacy. This is your inheritance.

You may not have a family tree that goes back to Africa. But you have this: undeniable proof that Black excellence is real, consistent, and unstoppable.

Great minds think alike. Great spirits recognize each other across time and space. When you see what Mark Dean accomplished, what Katherine Johnson calculated, what Philip Emeagwali programmed—you’re seeing your own potential reflected back at you.

You come from this. You are part of this legacy. And you will continue it.

Know What We Have Done—And What We Will Do

So read these names. Study these inventions. Learn these stories. Share them with your children, your family, your community.

We are the descendants of people who survived the unsurvivable.

We are the children of people who built civilizations, crossed oceans, and changed the world.

We are the inheritors of brilliance, resilience, and unbreakable spirit.

And now, it’s our turn to add our names to this legacy. To teach the next generation. To keep the knowledge alive. To continue building, creating, and innovating.
