Brief History of Clan Gregor

Clan Gregor, or Clan MacGregor, is one of the oldest Highland Scottish clans, with origins tracing back to the early 800s.
Among its most famous members is the legendary Rob Roy MacGregor of the late 17th and early 18th centuries.
The clan is also recognized as one of the earliest in Scotland to adopt the bagpipes in the early 17th century.

Origins of the Clan

At its height, Clan Gregor held extensive lands in Glen Orchy, Glenlochy, Glengyle, Glenlyon, and Glenstrae.
According to historian Iain Moncreiffe, the MacGregors descended from an ancient Celtic royal line through the Abbots of Glendochart.
This tradition is reflected in the clan motto: “Royal is my race.”

Connections to other clans of the Siol Alpin further support this claim of royal lineage. Another long-standing tradition holds that Gregor was a son of Kenneth MacAlpin,
although historians note that firm evidence is limited. It is also possible that Gregor descended from Griogair, son of Dungal, a co-ruler of Alba.

Most modern historians identify Gregor of the Golden Bridles as the first chief of Clan Gregor.
His son, Iain Camm (“One-Eye”), succeeded him as second chief before 1390.

Following the Wars of Scottish Independence, the barony of Loch Awe—covering much of MacGregor land—was granted to the Campbells by Robert the Bruce.
Despite the MacGregors’ service at battles such as Bannockburn, the Campbells consolidated control of the region, centered at Kilchurn Castle.
Over time, the MacGregors were pushed back into Glenstrae, marking the beginning of long-standing conflict.

16th Century – Conflict and Displacement

The death of Iain of Glenstrae in 1519 without direct heirs led to instability within the clan.
Leadership passed through contested claims, often influenced by the Campbells.

In 1547, Alistair MacGregor fought at the Battle of Pinkie Cleugh but died shortly thereafter.
Tensions escalated when Colin Campbell refused to recognize Gregor Roy MacGregor’s rightful claim to clan lands.

For ten years, Gregor Roy waged a campaign against the Campbells, operating as an outlaw in the Highland glens.
He was ultimately captured and executed in 1570. His son, Alistair, succeeded him but was unable to halt the continued persecution of the clan.

During this period, the MacGregors became known as the “Children of the Mist,” reflecting both their hardship and resilience.

Further tensions arose when John Drummond, the king’s forester, executed MacGregors for poaching.
His murder—claimed by the MacGregor chief—was condemned by the Privy Council.

17th Century – Proscription and Survival

In 1603, after the execution of two MacGregors, Alasdair MacGregor led over 400 men into Colquhoun territory,
resulting in the Battle of Glen Fruin. The MacGregors defeated a larger force, inflicting heavy losses.

In response, King James VI issued an edict abolishing the name MacGregor.
Anyone bearing the name was required to renounce it under penalty of death.
In 1604, the chief and eleven leaders were executed at Edinburgh’s Mercat Cross.

“The name of MacGregor shall be abolished… and any who assume it shall suffer death.”

Clan Gregor was scattered, with many forced to adopt other surnames such as Murray or Grant.
They were hunted relentlessly, yet continued to endure.

Despite persecution, the MacGregors remained loyal to the Crown.
During the Scottish Civil War, 200 clansmen fought for the Earl of Glencairn.
In recognition of their service, Charles II lifted the proscription—though it was later reinstated under William of Orange.

18th Century – Jacobite Risings and Legacy

Rob Roy MacGregor, born in 1671, became the clan’s most famous figure.
Though forced to use the surname Campbell, his exploits were later immortalized by Sir Walter Scott.

A staunch Jacobite, Rob Roy supported the 1715 uprising and later fought at Glen Shiel in 1719.
He died in 1734 and is buried in Balquhidder churchyard.

During the 1745 Jacobite rising, members of Clan Gregor fought at Prestonpans and were involved in actions that preceded Culloden.
In its aftermath, MacGregors openly defied restrictions, returning home armed and unchallenged through Campbell-held territory.

It was not until 1774 that the laws against Clan Gregor were finally repealed,
bringing an official end to generations of persecution.
