History of Masai Mara: How Kenya's Most Famous Reserve Came to Be
Research draws on Kenya Wildlife Service records, Mara Conservancy historical documentation, and oral histories from Maasai elders. Dates vary between sources — I’ve noted discrepancies where they exist. Some claims here I can’t fully verify; they come from conversations with older guides whose fathers worked in the reserve when it was first established.
“Mara” means “spotted” in the Maa language.
That’s the standard explanation. The land looks mottled from above — acacia trees, forest patches, dark shapes of animals scattered across golden grass. The Maasai named it for how it appears, not what it contains.
The Maasai didn’t call this a “reserve.” It was grazing land. Home. They’d been here for centuries before any European arrived.
Now the reserve welcomes over 400,000 visitors annually. (The exact number varies depending on who’s counting and whether they include the conservancies.) How did that happen? Flies, catastrophe, legal battles, and one game warden with a reputation for burning down poachers’ camps.
Why Didn’t Colonial Farmers Take the Mara?
They tried. Failed.
The British seized Kenya’s fertile highlands in the 1890s — the so-called “White Highlands” around Nairobi and the Rift Valley. Perfect farming country. Coffee. Tea. Wheat.
The Mara lowlands? Different story.
The British called it “Fly Country.” Tsetse flies carrying sleeping sickness. Horse sickness that killed pack animals. One account I’ve read describes a settler who lost his entire cavalry detachment to disease in 1907, though I haven’t been able to confirm which settler or where exactly.
The disease burden made farming impossible. Settlers who attempted to establish ranches gave up.
So the flies — not any conservation ethic — preserved the Mara’s wildness. Biology did what law couldn’t have done.
What Was the Emutai?
Between 1883 and 1902, something terrible happened to the Maasai. They call it the Emutai — “the wiping out.”
Rinderpest arrived first. A cattle plague introduced through colonial trade routes. Some estimates say it killed 90% of Maasai cattle. (That figure gets repeated often. Whether it’s precisely accurate, I don’t know. What’s certain is that it was catastrophic.)
Then smallpox. Then drought.
The Maasai population collapsed. Entire clans disappeared. Survivors scattered across a landscape suddenly emptied of cattle and people.
When British administrators surveyed the Mara in the early 1900s, they recorded it as “uninhabited.” Ripe for conservation.
They weren’t wrong that it was empty. They just didn’t ask why it was empty. The “wilderness” they claimed to preserve had been created by mass death barely a decade earlier.
How Did the 1904 Treaties Affect the Maasai?
The British didn’t simply take land. They negotiated. If you can call it negotiating when one side has rifles and administration and the other has just survived a catastrophe.
Between 1904 and 1911, colonial administrators pushed Maasai leaders to sign treaties giving up their most fertile northern grazing lands. The Maasai were relocated to reserves in the south — including the area that would become the Masai Mara.
They didn’t accept this quietly.
In 1913, Maasai leaders sued the British Crown in the High Court of Mombasa. One of the earliest examples of indigenous people using colonial courts to challenge land theft. They lost on a technicality — the court ruled they were “subjects of a foreign state” and couldn’t sue.
The legal argument was absurd. The case was dismissed. But if you ask guides whose families were affected, they know the story. It’s a point of pride. The Maasai fought back with the colonisers’ own tools.
Who Was Major Temple-Boreham?
Historical Milestone | Year Gazetted | Legal Status & Territorial Scope |
Wildlife Sanctuary | 1948 | Initial protection footprint limited to the western triangle (~520 km²). |
Game Reserve Upgrade | 1961 | Eastward expansion under the management of the Narok County Council. |
National Reserve Status | 1974 | Final designation; subsequent adjustments stabilized the park at 1,510 km². |
The Mara didn’t become a reserve automatically. It needed someone to push.
Local guides credit Major Temple-Boreham — Senior Game Warden in the 1950s.
Temple-Boreham was strict. Stories about him vary depending on who’s telling them, but the general picture: he burned poachers’ camps, tracked illegal hunters personally, and understood that the Mara Triangle was the ecological heart of the whole system.
His advocacy produced results:
1948: First protected area gazetted as Mara Wildlife Sanctuary. Small. Hunting still allowed under license.
1961: Expanded and upgraded to Masai Mara Game Reserve. Two years before Kenyan independence.
1974: Legal Notice 271 established current boundaries. 1,510 square kilometres.
I should note: the 1961 timing interests historians. Colonial administrators were rushing to establish protected areas before African governments took over. Whether that was conservation foresight or a final land grab depends on your interpretation.
A Note from David
I’ve stood at the Sand River dozens of times. Shallow, sandy crossing at the Kenya-Tanzania border. Most tourists don’t know the first safari camps in the whole Mara were pitched there in the 1920s.
Before lodges. Before vehicles. Wealthy hunters came by foot and horseback and camped along that river. When I take guests there and it’s quiet — no other vehicles, just wildebeest drinking — I tell them: you’re standing where the safari industry began.
The spectacle hasn’t changed. The vehicles have.

Places That Don’t Appear on Tourist Maps
Spend time with Mara guides and you’ll hear names.
The Lone Tree. A specific Balanites tree. Radio landmark for decades. When guides call a sighting there, local etiquette says leave a corridor for the animal to move toward Talek River. Self-drive tourists don’t know this rule. They park wherever.
Olpunyaia Swamp. Tourists call the area near Lookout Hill “the swamp.” Maasai guides call it Olpunyaia. Historical salt lick. The soil’s mineral content keeps elephant bulls here year-round, even when the migration is in Tanzania.
Paradise Plain. Not just pretty grassland. Known locally as the premier cheetah nursery. Migrating zebras keep grass short. Mother cheetahs teach cubs to hunt here because they can see danger coming. Generations have used this patch.
Old Boma Sites. You’ll see patches of neon-green grass that look out of place. Old cattle enclosure sites. Maasai move their bomas every few months. The concentrated manure creates nutrient hotspots that attract grazers for years. Finding an old boma is a guide’s trick for finding lions.
The “Radio Silence” Signal. If you see four or five vehicles pointing the same direction but guides aren’t talking on their radios, they’ve found something rare. Leopard usually. Maybe rhino. Radio silence means they’re protecting the sighting from the crowd.
Why Is the Mara Split Into Two Sections?
Ecosystem Sector | Primary Governing Body | Core Operating Rules & Reality |
Main National Reserve | Narok County Council | Standard daytime game drives; high seasonal vehicle density at river crossings. |
The Mara Triangle | Mara Conservancy (Since 2001) | Non-profit framework; stricter vehicle tracking and strict anti-poaching. |
Surrounding Conservancies | Private Maasai Leases | Controlled low-density tourism; unlocks walking safaris and night tracking. |
This confuses visitors.
The main reserve — roughly two-thirds of the total area — falls under Narok County Council. The western section, the Mara Triangle, is managed separately by Mara Conservancy.
The split happened because of problems. Through the 1980s and 1990s, the main reserve suffered. Poor infrastructure. Corruption allegations. Poaching increased. Roads deteriorated.
Management split in 1994. Mara Conservancy formed in 2000, began operations in 2001. By most accounts, the Triangle improved: better roads, stricter vehicle limits, more effective anti-poaching.
Whether the main reserve has caught up is debatable. I’ve heard different opinions from different guides.
What Are the Conservancies?
Starting in the 1990s, a different model emerged around the reserve’s edges.
Maasai landowners lease their land to tourism operators instead of grazing cattle. In exchange: regular payments, employment, community development funds.
Mara North Conservancy was established in 2009. Olare Motorogi, Naboisho, Ol Kinyei followed.
Conservancies offer what the main reserve can’t. Vehicle limits. Off-road driving for photography. Night drives. Walking safaris.
Today the conservancies surrounding the reserve cover more land than the reserve itself. They’ve become essential wildlife corridors — particularly for the great migration, that 1.5 million-strong movement of wildebeest and zebra between Serengeti and Mara.
Historical Traces You Can Still See
Keekorok Lodge. First permanent lodge. Built 1962. There’s a walkway to a bar overlooking a hippo pool — locals call it the Hippo Bar. Look at the guest book and historical photos near reception. Jomo Kenyatta visited. Prince Charles too. It’s the only place in the Mara where you can feel 1960s safari architecture.
The “Thunder Light.” Photographers prefer November and December — short rains. The sky turns dark purple while sun hits golden grass. Locals call it Thunder Light. More dramatic than the dusty haze of August peak season. (Though you risk mud and cancelled game drives.)
Gate History. Sekenani is the historical main entrance. Also the most congested. Local advice: enter via Talek or Oloololo if you want the “old” feeling of entering vast wilderness rather than a tourist attraction.
What Threatens the Mara Today?
Human-wildlife conflict. Communities around the reserve keep cattle. Lions kill livestock. Retaliatory killings happen. Compensation schemes help but don’t eliminate the problem.
Land conversion. Outside conservancies, some landowners subdivide and sell for wheat farming. Once fenced, wildlife habitat is gone.
Water. The Mara River depends on the Mau Forest catchment. Deforestation upstream reduces flow. This affects river crossings and hippo populations.
Tourism pressure. Some crossing points get absurdly crowded during peak season. Conservancies address this with vehicle limits. The main reserve still struggles.
Questions People Ask
When was the Masai Mara established? Current boundaries: Legal Notice 271 in 1974. A smaller wildlife sanctuary existed from 1948. The 1961 expansion created the “Game Reserve” designation.
What does “Mara” mean? “Spotted” or “mottled” in Maa language. Describes how the landscape looks from above.
Is it “Masai” or “Maasai”? Both used. “Maasai” is closer to indigenous spelling. Official gazettement uses “Masai Mara.”
Why is the Masai Mara famous? Big cat density. Annual wildebeest migration. Decades of BBC documentaries. Easy access from Nairobi.
How big is the Masai Mara? National reserve: 1,510 square kilometres. Including conservancies, protected ecosystem is roughly three times larger.
Plan Your Visit
Understanding history changes how you see the place.
This isn’t pristine wilderness that was always preserved. It’s land shaped by Maasai pastoralism, colonial policy, biological accident, and modern tourism. The wildlife adapted alongside all of it.
