Clan Chief, the Earl of Rothes
From 1457 the Clan Chief of Clan Leslie also held the position of Earl of Rothes. The Chief is currently the Hon. Alexander Leslie, the brother of James Malcolm David Leslie, 22nd Earl of Rothes (born 1958).
The progenitor of the Clan Leslie is a man named Bartolf who was a nobleman from Hungary, who came to Scotland in 1067. Bartolf was in the retinue of Edgar the Ætheling, brother of Saint Margaret of Scotland, who was later the queen of Malcolm III of Scotland. Bartholf later married Malcolm III's sister, Princess Beatrix of Scotland.
Bartolf was said to be a man of intellect and bravery and as a result Malcolm III made him governor of the royal Edinburgh Castle and gave him estates in Fife, Angus, the Mearns and Aberdeenshire. It is said that Bartolf helped the queen across a dangerous river on a horse and that Bartolf told her to "grip fast", which is where the Leslie family motto originates.
Bartolf established himself in the Garioch district of Aberdeenshire, at a place then known as Lesselyn. At Lesselyn he built a castle and it is from there that the name evolved into Lesley, and the various spelling variations. Bartolf's son was named Malcolm and was made constable of the royal Inverury Castle, which he held for David II of Scotland. His great-grandson was Sir Norman Lesley who acquired the lands of Fythkill in Fife, which were later called Lesley, in about 1282.
14th to 15th centuries: Rothes and Balquhain
The family sided with Robert the Bruce against firstly The Comyn in the Buchan and secondly Edward I and as a result were awarded further tracts of Aberdeenshire. They fought at the Battle of Bannockburn. Sir Andrew de Lesly was one of the signatories of Declaration of Arbroath, was sent to the Pope in 1320 asserting Scotland's independence. His grandson, Walter died at the Battlew of Harlaw in 1411 together with six of his cousins from Balquhain.
The chiefly line of the Clan Leslie passed to a junior branch of the family, from whom the present Earl of Rothes descends. In 1391, Sir Norman Lesley believed that his only son, David, had been killed in the Crusades, and therefore passed over his estates to his cousin, Sir George Lesley. Then in 1398, after George Lesley had taken possession of the castle and lands, David returned from the Crusades and claimed possession of his estate. The family managed to resolve the matter peacefully and in 1445 Sir George Lesley's grandson, also called George, was created a Lord of Parliament as Lord Lesley of Leven, and all of his lands were united into the barony of Ballinbreich. At some point before 1458, he was then advanced to the title of Earl of Rothes.
During the Anglo-Scottish Wars, George de Lesly was the Leslys' first Earl. His son George Leslie, the 2nd Earl, and his grandson were killed at the Battle of Flodden in 1513.The third Earl, also George, carried out a private family vendetta on the life of David Beaton, cardinal Archbishop of St Andrews. At the trial he was acquitted.
George Leslie, 4th Earl of Rothes, was one of the Scottish commissioners at the marriage of Mary, Queen of Scots, as heir to the throne of France in 1558. George, along with the Earl of Cascillus and two others, died in mysterious circumstances, believed to be poisoning for refusing to allow the crown of Scotland to be settled on the Dauphin of France.
Fetternear which became the home of the Leslies of Balquhain, Wardes, and Warthill includes the remains of a 14th-century palace, home of Bishop Alexander Kininmund who, in 1320, drafted the Declaration of Arbroath, the letter sent to Pope John XXII in Avignon declaring that the Scots would never be subjected to English rule. It also incorporates the remains of even earlier palaces and sites of settlement dating back 4,000 years.
John Leslie, Bishop of Ross was born in 1526. He was the most loyal of Mary, Queen of Scots's supporters during the turbulent times of 1562. It was John Leslie who wrote for her the famous History of Scotland. He, the second baron of Wardes, was awarded extensive lands in the Garioch from James IV and was five times married. He is now represented in the Garioch by the Leslies of Warthill descended from his second son. 
During the 17th century, Lesleys fought in Germany, France, Sweden and in the Baltic as mercenaries. Alexander Leslie, 1st Earl of Leven, fought on the Continent and then returned to Scotland to command the Covenanter army. His seat was Balgonie Castle or the Tower of Balgonie, which he improved and extended. Alexander Leslie won a great victory over the English royalists at the Battle of Newburn in 1640.
Wars of the Three Kingdoms
With the Scots, Leven went into England in 1640 and defeated the King's soldiers at the Battle of Newburn. For this, he was created Earl of Lewis by King Charles I. General Alexander Leslie of Balgonie fought for Gustavus Adolphus, the King of Sweden. He achieved great fame across Europe for his skills in war and returned to Scotland a Field Marshal.
In 1642, Leven went to Ireland and held command alongside Robert Munro (d. 1680) of the Scottish Army. They were sent to put down a rebellion of Irishmen who had killed Scots in Ulster. In 1644, Leven commanded Scottish Covenanter forces to victory over English Royalists at the Battle of Marston Moor in 1644. This battle was the largest battle of the English and Scottish Civil War, and one of the most decisive. It resulted in a Parliamentarian victory, which meant that the north of England was effectively lost to King Charles for the rest of the war.
During the Civil War, General David Leslie, Lord Newark, was victorious commanding his Scottish Covenanters force against a Scottish Royalist force at the Battle of Philiphaugh in 1645. The Royalist army of James Graham, 1st Marquess of Montrose, was destroyed by the Covenanter army of Sir David Leslie, restoring the power of the Committee of Estates.
Dunaverty Castle was a MacDonald stronghold. During the Civil War, it was besieged in 1647 by Scottish supporters of Oliver Cromwell who were led by David Leslie, from Clan Leslie. The MacDonalds surrendered and then 300 of them were massacred. The castle is nothing more than a ruin now, known as Blood Rock.
During the Civil War, David Leslie laid siege to the Royalist garrison at Kincardine Castle. The Castle was being held by the Chief of Clan MacNab. MacNab found that it would not be possible to maintain defense. During the night, sword in hand, at the head of 300 men, they cut their way through the besieging force. All made it through apart from the MacNab chief himself and one other man who were captured and sent to Edinburgh as prisoners of war. The chief was sentenced to death but he escaped and rejoined King Charles and continued to fight. Leslie's Scottish Covenanter force was defeated by the Scottish Parliamentarian forces who were at this point in time loyal to the Parliament of England and Oliver Cromwell at the Battle of Dunbar (1650). Leslie successfully commanded the Scottish Argyll Government Royalist forces at the Battle of Carbisdale (1650) where he was victorious against Scottish Royalist forces commanded by James Graham, 1st Marquess of Montrose.
Leslie's Royalist Forces were defeated at the Battle of Worcester in 1651. Leslie, who was now commanding Royalist forces, had supported the plan of fighting in Scotland, where royal support was strongest. King Charles, however, insisted on making the war in England.
The career of Walter Leslie (1607–1667) was all in Europe, where in the Thirty Years War he rose to prominence after leading the assassination of the Imperial generalissimo Wallenstein and his coterie in 1634, becoming a field marshal and imperial count.
John Hamilton-Leslie, 9th Earl of Rothes, was Vice Admiral of Scotland and governor of the royal Stirling Castle. During the Jacobite rising of 1715, he supported the British government and commanded a regiment of cavalry at the Battle of Sheriffmuir. He sold much of the clan estates but Leslie House near Fife remained the seat of the chiefly Earls until 1926.
